2.2 Installation

Considerations

Section 2: Installation and Setup

Proper installation of your projector will ensure the quality of your display. Whether you are installing a projector temporarily or permanently you should take the following into account to ensure your projector performs optimally.

Installation t

e '

Choose the installation type that best suits your needs: front or rear screen, floor mount or inverted mount.

Front Screen, Floor Mount Installation

ADVANTAGES CONSIDERATIONS

• Easy to set up

• Can be moved or changed quickly

• Easy to access

• Shares floor space with audience

Front Screen, Inverted Mount (ceiling) Installation

ADVANTAGES CONSIDERATIONS

• Does not take up audience space

• Projector is unobtrusive

• Projector cannot be accidentally moved

• Installation is more permanent

• It is more difficult to access the projector

Rear Screen, Floor Mount Installation

ADVANTAGES CONSIDERATIONS

• Projector is completely hidden

• Projector is easily accessed

• Usually good ambient light rejection

• Requires separate room

• Installation cost is usually higher

Screen Type

Rear Screen, Inverted Mount (ceiling) Installation

ADVANTAGES CONSIDERATIONS

• Projector is completely hidden

• Usually good ambient light rejection

• Requires separate room

• Installation cost is usually higher

Rear Screen, Floor Mount with Mirror

ADVANTAGES CONSIDERATIONS

• Projector is completely hidden

• Usually good ambient light rejection

• Requires less space behind screen than

other rear screen installations

• Requires separate room

• Installation cost is usually higher

Front Screen Installations

In front screen installations the projector and audience are positioned in front of the screen, which can be flat or curved.

Flat screens are most recommended with this projector. They offer a gain of about 1 with a viewing angle just less than 180°. This type of screen reflects incident light equally in all directions so the audience can see the display from various angles.

User’s Manual 2-3.

Section 2: Installation and Setup

Curved screens have a gain greater than 1 with a viewing angle much less than 180°. This type of screen does not reflect incident light equally in all directions instead it is concentrated in a viewing cone. The audience sitting within the viewing cone area will see a brighter image than those sitting just outside this area.

Rear screen installations

There are two basic types of rear screens: diffused and optical.

A diffused screen has a surface, which spreads the light striking it. Purely diffused screens have a gain of less than 1. The main advantage of the diffused screen is its wide viewing angle, similar to that of a flat screen for front screen projection. This type of screen is suitable when a wide viewing angle is required but there is low ambient room lighting.

Optical screens take light from the projector and redirect it to increase the light intensity at the front of the screen. This reduces it in other areas. A viewing cone, similar to that of a curved front screen installation is created. This type of screen is better suited for brightly lit rooms where the audience is situated within the viewing cone.

Screen size

Choose a screen size, which is appropriate for your lens and application. Keep in mind that if the projector will be used to display text information, the image size must allow the audience to recognize all text clearly. The eye usually sees a letter clearly if eyeto-text distance is less than 150 times the height of the letter. Small text located too far from the eye will likely be illegible at a distance no matter how sharply and clearly it is displayed.

2-4 User’s Manual

Section 2: Installation and Setup

To fill a screen with an image, the aspect ratio of the screen should be equal to the aspect ratio of the image (expressed as the ratio of its width to its height). Standard video from a VCR has a 4:3 or 1.33:1 aspect ratio. For example, to display a VCR output with a 4:3 aspect ratio onto a 10-foot (3m) high screen, the width of the screen must be at least 13.3feet (4m).

Ambient Li

htin

Other Considerations '

Projector Position and '

Mount

The high brightness of this projector is well suited for locations where ambient lighting might be considered less than ideal for projection. A typical room with ceiling lights and windows rarely requires special attention. Contrast ratio in your images will be noticeably reduced only if light directly strikes the screen, such as when a shaft of light from a window or floodlight falls on the image. Images may then appear washed out and less vibrant.

In general, avoid or eliminate light sources directed at the screen.

Other considerations and tips that can help improve your installation:

• Keep the ambient temperature constant and below 35°C (95°F). Keep the projector away from heating and/or air conditioning vents. Changes in temperature may cause drifts in the projector circuitry, which may affect performance.

• Keep the projector away from devices, which radiate electromagnetic energy such as motors and transformers. Common sources of these include slide projectors, speakers, power amplifiers, elevators, etc.

Choose the best screen size for the application. Since more magnification reduces brightness, use a screen size appropriate for the venue but not larger than required. Installing a large screen in a small room is similar to watching television at a close range; too large a screen can overpower a room and interfere with the overall effect. A good rule of thumb is to be no closer than 1.5 times the width of the screen.

Throw distance

Throw distance is the distance measured from your projector’s front feet to the screen. This is an important calculation in any projector installation as it determines whether or not you have enough room to install your projector with a desired screen size and if your image will be of the right size for your screen.

You can quickly estimate the throw distance by taking the horizontal width of the screen and multiplying it by the lens throw ratio. The result of this calculation tells you roughly how far back the projector should be positioned from the screen in order to project a focused image large enough to fill the screen. For example, using a 0.73:1 lens, throw distance would roughly be 0.73 x screen width.

IMPORTANT: Once you determine the type of lens and screen size you’re going to use, calculate the precise throw distance using the formula or graphs located in Appendix D. Due to lens manufacturing tolerances for lens focal length, actual throw distance can vary

5% between lenses described as having the same throw

ratio.

User’s Manual 2-5.

Section 2: Installation and Setup

Vertical and horizontal position

The correct vertical and horizontal position of the projector in relation to the screen depends on the lens type and the screen size. Ideally, the projector should be positioned perpendicular to the screen. This way, the image will appear rectangular instead of keystoned (trapezoidal).

The vertical position of the image can be offset – that is moved above or below the optical axis (lens center) by adjusting the fully motorized lens mount with the keypad. The amount of vertical offset available depends directly on the lens installed in the projector and can be slightly limited if horizontal offset has been applied. Vertical offset can also be expressed as the percent of half the image height OR the number of pixels of shift from lens center. Refer to Figure 2.1 for some illustrated examples of vertical offset.

Table 2.1 along with Figure 2.2 show the maximum vertical offset of a lens or alternatively, how much of your projected image will appear above or below lens center if the maximum vertical offset is applied using that lens.

The horizontal position of the image can be offset – that is moved to the left or right of lens center, by adjusting the fully motorized lens mount through software. The amount of horizontal offset available depends on the lens installed and if the image has already been vertically offset. Horizontal offset can also be expressed as the percent of half the image width – the number of pixels of shift to one side of lens center. Refer to Figure 2.3 for some illustrated examples of horizontal offset.

Mounting

There are several methods for mounting the projector. Depending on your chosen installation, one method may be more suitable than another. In typical front and rear screen installations the projector can be mounted to a secure and level surface, such as a table or cart. Carts are useful when the projector has to be moved during a presentation or from site to site. It is recommended you lock the wheels on a cart, when it’s in position, to prevent someone from accidentally moving it during a presentation.

CEILING MOUNT - The projector can also be inverted and suspended from the ceiling

using a specially designed ceiling mount fixture. This type of mounting is recommended for fixed installations and for those that want the projector out of plain view or have a limited amount of space for projector and audience. For more information, contact your dealer.

Use only the CHRISTIE approved ceiling mount kit designed for

your projector. Refer to the installation instructions and safety guidelines provided in the kit.

SPECIAL MOUNTING – The projector can be rotated (front-to-back) up to 360 degrees

and mounted without it affecting performance. However, the side-to-side tilt limit of the projector must not exceed ±15 degrees. This tilt limit is required to ensure optimal performance of the projector.

Adjusting projector height

You can modify the height of the projector to remedy a slightly uneven mounting surface by adjusting the two feet threaded into the bottom chassis. Turn each foot clock-wise or counter-clockwise until the project is level on all sides.

Folded Optics

In rear screen applications where space behind the projector is limited, a mirror may be used to fold the optical path. See Figure 2.5. The position of the projector and mirror must be accurately set – if considering this type of installation call your dealer for assistance.

2.4 Connecting

Communications

Section 2: Installation and Setup

As an alternative to the projector’s keypad or remote, you may wish to communicate with the projector using a PC or other controller. Such a device sends commands and receives feedback via serial links (RS232 and RS422), Ethernet or GPIO communications to the projector, all described below.

Remote Ke

ads '

Serial Port Connections '

As desired, direct the projector’s IR remote keypad towards the display screen or the projector’s IR sensors. Alternatively, connect a wired (tethered) version of the remote to the 3.5mm RCA jack labeled as

REMOTE on the projector’s input panel. Note that

response to a wired keypad must also be enabled in the Communications menu—see

3.6, Adjusting System Parameters and Advanced Controls for more information.

There are two types of serial ports available on the projector: RS232 and RS422. You can connect a device with a serial interface, such as a computer to either of these connectors (not both) and control the projector remotely by entering specific serial communication commands.

Connecting RS-232

The two 9-pin DIN connectors labeled RS232 IN and RS232 OUT on the input panel are dedicated to serial communication (see Figure 2.10). Using the appropriate serial communication cables (see Appendix C) connect the controlling source, such as a personal computer to the RS232 IN connector. Then set the baud rate to match that of the computer. Refer to Section 3 for details on changing the projector’s baud rate.

Figure 2.10. Connecting RS232

Connecting RS-422

If you wish to control the projector with a computer and or other controlling device with RS-422 capability, connect a RS-422 serial communication cable between the computer and the RS-422 port on the projector (see Figure 2.11). RS-422 is better suited for serial communication over long distances then is RS-232 communication.

Use the RS-422 port only if your device had RS-422 capability – always consult the literature provided with your equipment before connecting. Connecting to the RS422 port with incompatible equipment could damage your projector.

User’s Manual 2-15.

Section 2: Installation and Setup

Ethernet Communications

Figure 2.11. Connecting RS422

Ethernet Communications

To add the projector to an existing Ethernet network with other equipment such as controllers and other projectors, connect standard CAT5 Ethernet cable between your Ethernet controller (or hub) and the Ethernet port on the side of the projector.

Connecting Multiple '

Projectors

Upon connection to an Ethernet network, the projector’s factory default IP address of

0.0.0.0.0 will automatically enable the DHCP function (if available on the network) to assign a new IP address that is valid and unique for that network. Or, if there is no DHCP function available on the network (or if a specific static IP address for the projector is preferred or required), you can set the address in the Ethernet Settings menu or via an ASCII serial command.

Regardless of how it is assigned, once a projector has a valid and unique address it will respond to commands sent to this address. To determine the projector’s current IP address, consult the Status or Communications menus.

Refer to Section 3 for further information about setting up and using a projector connected via Ethernet.

Log on to www.christiedigital.com for detailed information on ChristieNET.

RS-232 NETWORK: If you want to connect multiple projectors in a network with serial

communication, connect the controlling source to the RS232 IN connector of the first projector in the network. Then take another serial communication cable and connect one end to the RS232 OUT connector and the other end to the RS232 IN connector of the next projector. Continue this pattern of connection with all projectors in the network. The last projector in the network will only have a connection to the RS232 IN connector. See Figure 2.12.

2-16 User’s Manual

Section 2: Installation and Setup

Figure 2.12.

MIXED NETWORK: To control multiple projectors with a computer/controller having an

RS422 interface, first set them all to the same baud rate as your RS422 controller.

NOTE: You must enable this combination of RS422 and RS232 in the Communications menu. Set the “Network Routing” option to “RS232 and RS422 Joined”. See Section 3 for details.

Then chain the projectors together by connecting an (already connected to the computer/controller through the

RS232 port of the first projector

RS422 port) to an RS232

port on the next projector in the chain. Continue connecting projectors in this manner until you’ve reached the last projector in the chain, so that only the last projector has one unused

RS232 port. See Figure 2.13.

Figure 2.13.

Note that communication parameters such as baud rate must be set to match the particular controlling device before connecting as a network—refer to the documentation that came with your controlling device in order to determine the proper baud rate. See 3.6, Adjusting System Parameters and Advanced Controls if you need help changing the projector baud rate. In addition, set the Network Routing to “RS232 and RS422 Joined” if you want to reach all projectors.

NOTES: 1) To avoid damage, connect only properly wired serial communication cables. See Appendix C for details. 2) It is recommended that each RS232 communication cable be no more than 25 feet in length. Use high quality cables.

User’s Manual 2-17.

Section 2: Installation and Setup

ETHERNET NETWORK SETUP: To add one or more projectors to an Ethernet network,

use standard CAT5 cable to connect each projector’s Ethernet port to a hub belonging to the network. A controller or PC must also be connected to the hub. See Figure 2.14.

Figure 2.14.

SETTING THE PROJECTOR’S IP ADDRESS: Upon connection to most Ethernet

networks, each projector’s factory default IP address of 0.0.0.0 triggers the network’s DHCP (Dynamic Host Configuration Protocol) server function to automatically assign an IP address that is valid and unique for use on that network. Depending on the network, this DHCP-assigned IP address usually remains stable for a single session, but may change with subsequent power-ups and logins. On some networks, the address will remain stable from session to session. In all cases, the projector’s IP address and port appear in the Status menu as well as the Ethernet Settings submenu. See Figure 2.15.

2-18 User’s Manual

Figure 2.15. Setting the Projector’s IP Address

Note that if a projector’s IP address is anything other than 0.0.0.0 (shown as

000.000.000.000 in the Ethernet Settings menu) upon connection to an Ethernet network, or if DHCP is not available on the network, the automatic DHCP server function for supplying a valid and unique IP address to the projector is disabled. Instead, a specific and static IP address must be defined in projector memory—enter the new address in the Ethernet Settings submenu, or send to the projector via a serial command. The IP address will be in effect until it is changed again, or until the DHCP checkbox is re-enabled for use with a DHCP server on the network.

CHANGING THE PORT#: On some Ethernet networks, firewall restrictions may require

that the port number of the projector be changed from its default of 3002. If so, enter a new port number in the Ethernet Settings menu or include the new port# in an XIP serial command sent to the projector. It is highly recommended not to use a port# below 1000, as these ports are typically reserved for and used by common IP applications.

Section 2: Installation and Setup

SUBNET MASK AND DEFAULT GATEWAY: The Subnet Mask and Default Gateway are

automatically assigned when DHCP is enabled. If a static IP is being used, it must be assigned before the subnet mask. The Default Gateway is an optional router device used to send and receive data outside the subnet.

Networks '

By default, communications originating from one type of serial controller—RS232 vs. RS422 vs. Ethernet—stay on the corresponding network path. A “Separate” setting indicates this separation for “Network Routing” in the Communications menu. If you are using an RS422 controller, for example, it will communicate only with the projector to which it is connected unless you change this setting to either “RS232 and RS422 Joined” or “All Joined”.

Communicating to '

All Ports

To relay all messages to all ports—RS232, RS422, and Ethernet—set the “Network Routing” option in the Communications menu for each projector to “All Joined”. This configuration is useful if you are using a non-RS232 controller with the RS232 linking available between these projectors. For example, you may want to use both an RS422compatible controller and an Ethernet-connected PC for working with a network of projectors linked via their RS232 in/out ports.

Figure 2.16.

To isolate just RS422 communications, select “RS232 and Ethernet Joined”. In Figure

2.16, only projector #3 will respond to the RS422 controller. To isolate just Ethernet communications, select “RS232 and RS422 Joined”—only projector #1 will respond via Ethernet.

Section 2: Installation and Setup

2.6 Power Connection

The North American rated line cord is provided with each projector. Ensure

that you are using a line cord that meets the appropriate rating standards (CCC for use in China, PSE for use in Japan).

Plug the line cord to the AC receptacle located at the back of the projector, below the input panel, and the 3-pronged end into a grounded AC outlet. Make sure the socket outlet is installed near the equipment and is easily accessible. The input voltage to the projector must be capable of 100 – 240 VAC in 500W and 1000W models and 200240VAC in 1200W models. (See also Section 6 – Specifications for complete details on all power requirements.)

Use the approved North American-rated line cord supplied with the projector. If you are connecting to an area outside of North America make sure you are using an appropriately rated line cord.

Always power down the projector before unplugging the AC line cord. Wait 5-10 minutes for the main exhaust fan to turn off and for the lamp to cool sufficiently before unplugging the projector.

WARNINGS

Do not attempt operation if the AC supply and cord are

not within the specified voltage and power range.

Wait for the cooling fans to turn off before unplugging the

projector.

Lens Mount & Pro

ection Lenses '

The projector is built with a motorized lens mount that allows for easy lens control and adjustment. This includes such functions as adjusting vertical and horizontal offsets, zoom and focus. The lens mount can be fitted with any one of the available optional lenses – see Section 6 - Specifications.

• Zoom and Focus – There are two internal lens motors that allow for quick motorized adjustment of zoom and focus. Adjust zoom to fit the displayed image on the screen and adjust focus to improve the clarity of the image.

NOTE: You can manually override zoom and focus adjustments set with the remote. Turn the outer ring on the projection lens to adjust focus and the inner ring to adjust zoom.

• Lens Offset – Vertical and horizontal offset is performed on the lens mount through the use of DC motors.

• Shutter – Standard on all models the shutter allows you to turn the screen absolutely black when in the “on” state.

• Optical Aperture – Enables adjustment of light output and contrast ratio.

NOTES: 1) The projection lens is shipped separately from the projector. 2) Use the lens cap when transporting the projector to avoid scratching and damaging the lens, which could affect your displayed image.

There is no status display on the input panel. The only status display is part of the built-in keypad located at the rear of the projector.

There are numerous air vents located around the projector. It is important these vents remain unobstructed. Adequate airflow through the projector will prevent it from overheating.

The two IR sensors located on the projector receive transmissions from the IR remote from up to 100 feet away. It is important to keep the transmission path to these sensors unobstructed for uninterrupted communications with the projector. The front IR sensor is located next to the projector’s nameplate and the rear IR sensor is located at the back of the projector just above the status LED display.

The lamp door is located at the back of the projector, which provides easy access to the lamp module for replacement. See Section 4 for lamp replacement procedures.

Section 3: Operation

3.2 Using the Remote or Built-In Keypad

Built-in '

ad Commands '

Laser radiation is emitted from the laser diode in the remote. Do not look

directly into the beam of the remote.

The projector is typically controlled using one of the following keypads:

• Built-in Keypad located at the back of the projector

• Remote Keypad for tethered or tetherless control up to 100 feet away

(includes cable for use as a wired remote)

While each of the keypads provides complete control of the projector, they differ slightly in their arrangement of keys and in what functions can be accessed directly with a key press rather than requiring use of the menu system. You may find one keypad more convenient than another for your specific installation and application.

NOTE: The remote keypad has a single IR protocol and can be converted to a wired remote by connecting the cable provided with the projector to the RCA jack labeled as

REMOTE on the input panel.

To control the projector when signals from a remote keypad cannot reach the projector, use the projector’s built-in keypad (Figure 3.1). The nearby LED display provides feedback indicating current status and activities of the projector. Because the built-in keypad has fewer keys than the remote keypad, certain projector functions are accessible only

Figure 3.1. Built-in Keypad

through the menu system rather than via a direct key.

IR Remote '

NOTE: The built-in keypad cannot be disabled.

Refer to the key descriptions provided for the IR remote – see Figure 3.2.

The IR remote keypad controls the projector by way of wireless communications from a battery-powered infrared (IR) transmitter. Use the IR remote keypad the same way you would use a remote keypad supplied with a TV or VCR. When making key presses, direct the keypad either toward the screen or toward the front or rear of the projector. One of the two IR sensors on the projector will detect the signals and relay the commands for internal processing.

Contrast

Press

to change the amount of white in your images. Use keys until you reach the desired level of contrast—for best results, start low and increase so that whites remain bright but are not distorted or tinted and that light areas do not become white (i.e., “crushed”). Conversely, low contrast causes dim images. See 3.5, Adjusting the Image (Image Settings subsection).

Bright

Brightness

Press

Bright

to increase or decrease the amount of black in the image. Use keys until you reach the desired level of contrast—for best results, start high and decrease so that dark areas do not become black (i.e., “crushed”). Conversely, overly high brightness changes black to dark gray, causing washed-out images. See 3.5, Adjusting the Image (Image Settings subsection).

Gamma

“Gamma” determines how gray shades are displayed between minimum input (black) and maximum input (white) for a given amount of signal. The proper setting helps maintain optimized blacks and whites while ensuring a smooth transition for the “inbetween” values utilized in grays. Unlike brightness and contrast controls, the overall tone of an image can be lightened or darkened without changing the two extremes and your images will be more vibrant yet with good detail in dark areas when using the Gamma control.

The normal gamma setting of 2.2 is correct for most signals and conditions. If excess ambient light washes out the image and it becomes difficult or impossible to see details in dark areas, lower the gamma setting to compensate. This will improve contrast ratio while maintaining good details for blacks and whites

Input 3, Input 4, Input 5

image will be displayed according to the following:

If it is the first time you have used the source/input (or if you used the input but did not define a channel by adjusting anything), the projector will recognize the new input signal based on its frequencies and polarities, and will automatically display an image according to default settings for such a signal. In general, the image from the new source will be as large as possible without losing its aspect ratio. This and other default image settings depend on the incoming source.

If you used the source once before and changed a display parameter such as contrast, V-Position, etc., then a channel was automatically created and still exists

in projector memory (see below). Using one of the

Input

keys will automatically recall this channel—and all its setup parameters—and update the display accordingly.

If more than one channel exists for the input, the image will be displayed according to the setup parameters for the first channel with matching characteristics.

NOTE: Inputs 7 and 8 require the Dual SD/HD-SDI module in either of the projector’s option slots. For their selection, see also 3.2 Using the Remote or Built- In Keypad.

CHANNEL - A channel is a collection of measurements, locations and settings that

tailor the display of a signal to your specific needs. Since source types and applications can vary greatly, you will likely want to adjust and define a wide variety of parameters, such as brightness, contrast, size, etc., in order to customize and optimize the display from or for a particular source. For example, the display settings you choose for a VCR source may be very different from those you choose for a high-

In order to access channels by using the keypad, you must first create the channels. See below.

Creating a Ne Channel

– AUTOMATIC –

To use a new source with the projector, a new

channel must be added to projector memory so that the projector will respond properly to an input signal from that source in the future. A new channel can be created automatically, as described here, or it can be copied from an existing channel and then edited as necessary (see Copying or Deleting Channels later in this section).

When you select a direct input ( channels in the projector are searched for matching input and signal parameters – this only occurs if Auto Source is enabled on these channels. If no match to the incoming input signal is found in currently defined channels, a new channel is temporarily created based on factory-defined defaults for this type of signal. The channel number assigned is the lowest available number from 01-50.

NOTES: 1) An automatic channel will be discarded unless one or more of its parameters are changed and will not appear in the channel list (see below). 2) If two channels have the same distinguishing source characteristics except for the reversal of sync connectors (i.e., H-sync and V-sync, are switched), they are still defined as distinct channels. 3) You cannot define a new channel without an incoming signal.

If the incoming signal does match an existing channel, the image will be set up and displayed as usual according to the parameters currently defined for that channel.

USING A CHANNEL: You can normally select a channel at any time by pressing

Resize Presets

NOTE: The same resize presets are available to all HD2 widescreen models. Please note however, the graphics used to describe each preset in this section are of the SXGA+ models only.

Select a Resize Presets option to quickly display an image in its native resolution or to automatically resize an image to closely fill the projector’s native resolution or to optimize the width or height of your display. Size, Position and Blanking parameters will automatically adjust accordingly or, if Blanking is set first, which defines an Active Input Area, Resize Preset scaling will occur in this region of interest only. Resizing options are explained in detail below.

WHAT IS THE RESIZING DEFAULT? By default when displaying a new source, your

image will utilize as much of the projector’s display area as possible for the type of incoming source data, but with minimal or no changes to aspect ratio. See Select “Default” below.

3-20 User’s Manual

Section 3: Operation

WHEN “CUSTOM” APPEARS: The “Custom” re-size descriptor automatically appears in

the Size and Position menu when any of the values for Size, Vertical Stretch, H- Position, V-Position or Blanking do not correspond to those for a preset. This option is not offered in the Resize Presets pull-down list.

• Select

“DEFAULT” for most sources (factory default). The image will be centered

and displayed as large as possible depending on the type of source.

• Select

“NO RESIZING” to display the image in its native resolution, which may or

may not match the projector’s resolution. For example, for a source with a native resolution of 800 x 600, “No Resizing” in an SXGA+ projector will use the central 800 x 600 pixels and have a black border—the black border areas are unused areas. See below.

• Select “FULL SIZE” to use all pixels

for displaying the image, regardless of source or original aspect ratio. Incoming source material having a different aspect ratio than the projector will be stretched for display.

• Select

“FULL WIDTH” to fill the

projector’s display from left-to-right without changing the original aspect ratio of the image. Depending on the source, data at the top and bottom may be discarded (cropped), or the display may have black borders at the top and bottom (called “letterboxed”).

User’s Manual 3-21.

Section 3: Operation

• Select “FULL HEIGHT” to fill the display from top-to-bottom. Depending on the

source, this may create borders.

• Select “ANAMORPHIC” to display an anamorphic image

in its native 16:9 aspect ratio. The image will fill the screen from side-to-side and be centered between black bars at top and bottom.

Size

“Size” controls both the image width and height in tandem, maintaining the current aspect ratio (proportion) of the displayed signal data.

Vertical Stretch

“Vertical Stretch” adjusts the height of the image while keeping the width constant. Use “Vertical Stretch” to change the aspect ratio of the display.

Pixel Track

Steady flickering or several soft vertical stripes or bands across the entire image indicates poor pixel tracking. Proper pixel tracking helps ensure that the image quality is consistent across the screen, the aspect ratio is maintained, and that the pixel phase can be optimized (described below). Tracking determines the frequency of the pixelsampling clock, indicated by the number of incoming pixels per line, so that all pixels generated by a particular source are sampled.

NOTE: By default, the projector samples at the correct frequency for most sources.

For best results, use a good test pattern such as a smooth gray consisting of a clear pattern of black and white pixels, or a similar “half on, half off” graphic image, such as the Windows shutdown screen. Adjust the slide bar until the vertical stripes broaden to the point where one large stripe fills the image. If the image still exhibits some shimmer or noise, adjust Pixel Phase (below).

3-22 User’s Manual

Pixel Phase

NOTE: Adjust “Pixel Phase” after “Pixel Tracking”.

Adjust pixel phase when the image (usually from an RGB source) still shows shimmer or “noise” after pixel tracking is optimized. Pixel phase adjusts the phase of the pixelsampling clock relative to the incoming signal.

Section 3: Operation

For best results, use a good test pattern such as a smooth gray consisting of a clear pattern of black and white pixels, or a similar “half on, half off” graphic image, such as the Windows 2000 shutdown screen. Adjust the slide bar until the image stabilizes and each pixel is clearly defined. You may notice that you can stabilize the image at more than one point—i.e., you may find that the image appearance at “11” is identical to the image appearance at “38”, thus you can use either setting.

If some shimmer from a video or HDTV source persists, use the “Filter” control to remove high-frequency noise from the signal.

H-Position

This option moves the image right or left within the area of available pixels.

NOTE: The value shown represents where the approximate center of the image lies in relation to the total number of pixels available horizontally. This varies widely according to the signal—watch the image while adjusting.

V-Position

This option moves the image up or down within the area of available pixels.

NOTE: The value shown represents where the approximate center of the image lies in relation to the total number of pixels available vertically. This varies widely according to the signal—watch the image while adjusting.

ACTIVE INPUT WINDOW: This read-

only value indicates the current size (i.e., area) of your displayed data or “region of interest” as defined by the blanking controls. By default, the projector automatically determines what portion of its full resolution to use, and pixels in the surrounding borders are turned off. You can also specify a specific active input window size by adjusting one or more “Blank” settings. For example, if you have blanked (cropped) 100 pixels from both the left and right edges of an incoming source of 1400 x 1050, the remaining active input window will be reduced to 1200 x 1050. When using SD or HD or a decoded video source at

INPUT 3 or INPUT 4, the default blanking of “0” defines an active input

window of 720 x 483.

Contrast

SHORT CUT: Press

(

Contrast

and adjust the slide bar.)

“Contrast” increases or decreases the perceived difference between light and dark areas of your image (0-100). For best results, keep close to 50. If contrast is set too high, the light parts of the image lose detail and clarity. If the contrast is set too low, the light areas will not be as bright as they could be and the overall image will be dim. For best results, start with a low value and increase so that whites remain bright but are not distorted or tinted, and that light areas do not become white (i.e., are “crushed”).

NOTE: If the environment lighting changes, an adjustment of Gamma is recommended (see below).

Brightness

(

SHORT CUT: Press

Bright

and adjust the slide bar.)

“Brightness” increases or decreases the amount of black in the image (0-100). For best results, keep close to 50. Start with a high value and decrease so that dark areas do not become black (i.e., are “crushed”). Conversely, high brightness changes black to dark gray, causing washed-out images.

Gamma

SHORT CUT: Press

(

Gamma

and adjust the slide bar.)

“Gamma” is a global setting that determines what gray shades are displayed between minimum input (black) and maximum input (white) for all signals. A good gamma setting helps to optimize blacks and whites while ensuring smooth transitions for the “in-between” values utilized in other colors. Thus, unlike “Brightness” and “Contrast” controls, the overall tone of your images can be lightened or darkened without changing the extremes, and all images will be more vibrant while still showing good detail in dark areas.

User’s Manual 3-25.

Section 3: Operation

Gamma is used to fine-tune the gamma table currently in use, ranging from 1 – 3 (2.2 = default). If excess ambient light washes out the image and it becomes difficult or impossible to see details in dark areas, lower the gamma setting to compensate. This will improve contrast while maintaining good details for blacks. Conversely, if the image is washed out and unnatural, with excessive detail in black areas, increase the setting. In high ambient light conditions, lower gamma may produce better results than higher gamma. Gamma of 2.2 (default) indicates the gamma table has not been adjusted. For more information, refer to Advanced Image Settings submenu, Gamma Table. Again, good gamma improves contrast while maintaining good details for blacks.

Filter

The proper filter setting is automatically set for virtually all signals, and rarely needs to be changed. It applies a low pass filter for noise reduction in the incoming input signal, particularly for HDTV or SDTV. Applied in the analog domain before sampling, this filtering removes high frequencies and thus reduces pixel phase noise (note this also reduces signal bandwidth). Override only if standard pixel tracking and phase adjustments do not adequately clear up a “noisy” video signal, or if a graphics signal appears overly “soft”. Both instances indicate that “Filter” may be set to the wrong option.

Detail

“Detail” adjusts the sharpness of a video image so that edges remain clearly defined. It can be particularly useful if a significant “Noise Reduction” adjustment has caused the image to appear too soft. Adjust until the display is as sharp as desired, keeping in mind that because “Detail” adds some high frequencies back into the image, it can also re-introduce a certain degree of noise.

Noise Reduction

“Noise Reduction” is similar to the “Filter” control, but operates in the post-sampling digital domain with a more subtle effect. Higher settings are most useful for clearing up noisy RGB images such as those from a PC. Adjust as desired, keeping in mind that reducing noise (which reduces high frequencies) may also soften the image.

Color Space

“Color Space” determines how the color components of an analog input signal are decoded for accurate color in the display. Selecting a color space option is useful only for analog signals and certain digital sources connected to or

INPUT 6. Although color space for these analog signals is

INPUT 1, INPUT 2, INPUT 5

automatically determined by the projector, in some circumstances you may wish to override this and manually set a specific color space.

NOTE: For many digital signals or for signals connected to

• Scan-quadrupled sync-on-green.

For these signals, change the Color Space to RGB, and then define a new channel for future use.

Gain Control (AGC) affects decoded video images only. Enter a checkmark (default) in most instances—this activates the decoder’s AGC circuit to ensure properly bright images. Delete the checkmark if a decoded video image exhibits strange color artifacts such as stripes in highly saturated colors, indicating an incompatibility between this source and the AGC.

VIDEO STANDARD: For all but the more unusual video

standards available in the world, the projector automatically detects the incoming horizontal and vertical frequencies and sets the projector’s processing of this signal to the corresponding standard. The current video standard name appears in the Video Options submenu, and includes an “A” if it has been auto-detected. Press

to view or select a different video standard from those available to the projector—any that are disabled have frequency characteristics that differ from those of the incoming signal. Selecting a specific standard forces the projector to process the signal according to this standard.

NOTE: Best results are obtained with defined channels. Otherwise, switching from one video source to another can sometimes cause slight disturbances in the display, indicating that the Auto function is struggling. Recover by briefly selecting a different video standard, then going back.

Section 3: Operation

NOTE: Generally, use “Auto” for all instances EXCEPT: 1) a poor quality input signal or 2) a black-and-white video signal. In order to detect and display such signals, select the relevant standard from the list.

INPUT VIDEO BLACK: This control

compensates for incoming elevated black levels present in certain video signals, and ensures that blacks in the display are neither crushed (i.e., where dark grays appear black) nor excessively elevated (i.e., where blacks appear dark gray). By default, the projector automatically determines the best setting according to the type of incoming video signal:

•

0 IRE – Used for DVD output with “enhanced black”, SECAM, most PAL

standards, and Japanese NTSC.

•

7.5 IRE – Used for most NTSC video signals.

For some types of video, you can override the setting. The control is disabled for other types of video (and all graphics sources). Generally, if black appears crushed when brightness = 50, choose “0 IRE”. If black appears excessively elevated, use “7.5 IRE”.

COLOR: This slide bar adjusts the color saturation level, i.e., the amount of color in a

video image. Lower settings produce less saturated colors — for example a setting of “0” produces a black and white image. If the color level is too high, colors will be overpowering and unrealistic.

TINT: This slide bar adjusts the red/green color hue for true color reproduction of

video and HDTV signals connected to Input 3 or 4. For best results, adjust tint while displaying an external test pattern—otherwise, it is recommended that tint remain at its default setting.

DECODER LUMA DELAY: This control affects any incoming composite or S-video

signal, delaying the luma signal (intensity) in relation to the chroma (color). In the image, increasing the luma delay will move luma (seen as a shadow where colors overlap) to the right slightly, with colors remaining in place. Decreasing this delay will move the shadow slightly to the left. If necessary for your current source, adjust so that no shadows occur with adjacent colors.

Input Levels

— SUBMENU

NOTES: 1) Because the projector automatically optimizes input levels for all but the most unusual of sources, it is recommended that only experienced users use the Input Levels submenu. 2) Before beginning, check that overall contrast and brightness settings are near 50 and that color temperature is properly set up on an internal grayscale test pattern. 3) There must be at least 2 consecutive white pixels present in the image for proper “Auto Input Level” function. Leave this control off after use.

3-28 User’s Manual

Section 3: Operation

Good RGB or input levels— that is, the drives and black levels for each of the three colors, red, green and blue— ensure that images from analog sources other than decoded video have maximum contrast without crushing black or white. By default (and in an “Auto Setup”), the projector automatically determines the best input levels by monitoring image content and adjusting the controls appropriately—further adjustment is typically not required to obtain proper blacks or whites.

NOTE: This automatic adjustment requires at least 6-12 consecutive white pixels in the image. Without these pixels, input levels may produce skewed colors, particularly in non-video images.

However, for a very unusual source exhibiting one or more overly high black levels (typically caused by a noisy source causing black level spikes), an experienced user may prefer to use the Input Levels menu (shown above). These adjustments, which together serve as a calibration process compensating for differences in sources and cabling, enable an experienced user to perfect the source image input levels and eliminate the “overshoot” and “undershoot”. Note that Input Levels are of limited use with digital signals, but do offer some ability to tweak poorly mastered source materials.

NOTES: 1) Input levels apply for the current source only, but for any color temperature used. 2) Assuming that color temperature has been set up based on the internal test patterns, you can then set up input levels for a given source so that it matches the color temperature of the internal test patterns.

AUTO INPUT LEVEL – Temporarily enter a checkmark only if you are an experienced

user and you have an unusual source that you feel needs further color temperature and/or input level adjustment. This compensates for incoming out-of-range drives (white) and black levels (black) that would cause “crushing” of light and dark colors in the image. After entering a checkmark, wait for the six slide bar values to stabilize, then delete the checkmark and exit. The Auto Input Level is automatically turned off upon exit from the Input levels Menu.

BLACK LEVELS AND DRIVES - To check your image levels and adjust these controls:

1. Make sure overall “Contrast” and “Brightness” settings are both set to near 50.

NOTE: Not required for “Auto” adjustment.

Contrast

•

= 50 (approx.)

Bright

= 50 (approx.)

2. Check the color temperature setup using an internal grayscale test pattern, making

sure to obtain a neutral grayscale. NOTE: Not required for “Auto” adjustment.

User’s Manual 3-29.

Section 3: Operation

3. Confirm that you are using an analog source not connected to INPUT 3 or INPUT

4, as Input Levels are not applicable for digital sources or sources going through the decoder. A grayscale is recommended.

4. If the blacks and/or whites appear OK, input levels do not need adjustment. If

black levels are too high (and/or whites are too low, which is rare), you likely have a noisy source that is producing skewed input levels. Continue with Step 5.

5. Temporarily enable “Auto” in the Input Levels submenu. Wait for all 6 values to

stabilize. Alternatively, do not use “Auto”—reduce black levels manually instead. Judge by eye and change one or more of the six levels as necessary to obtain proper blacks and whites. You may want to see only a certain color while adjusting—use the “Color Enable” option (described below).

6. Delete the “Auto” checkmark and leave the Input Levels menu.

IMPORTANT: Do not use Input Levels to adjust color temperature. This will distort Contrast and Brightness functions as well as color temperature.

AUTO COLOR ENABLE – When a checkmark is present, selecting a specific black level

or drive to adjust will automatically enable the corresponding color in the display. Delete the checkmark to see all colors, or to enable a different specific color through the Color Enable Control.

CLAMP LOCATION – This option (formerly known as sync tip

clamping) can brighten the image produced from certain high-

resolution high-frequency graphic sources. The projector automatically selects the best clamp location for almost all sources. Use the normal Back Porch location if the image is either sufficiently bright or overly bright. Select Sync Tip if the image appears unusually dim, if there are horizontal streaks across the image, or if there is significant color drift. This moves the clamping pulse from the normal back porch location (which is likely too short) to the tip of the horizontal sync pulse. Tri Level is typically needed for an HDTV source.

COLOR ENABLE –Select which color or colors you want to see in the display, useful

while working with color temperature white levels or input levels.

PEAK DETECTOR – The Peak Detector is a tool to assist with defining individual input

levels, enabling you to accurately set the Input Levels for any particular source with the appropriate image. Enabling the Peak Detector activates a special operating mode for detecting only pixels that are considered black or white—all other levels are displayed as a mid-level gray. When used with a smooth grayscale pattern in which black and white are known to be at opposite edges of the image, you can watch these isolated areas while adjusting individual black levels and input drives until both black and white edges are just visible and distinguished from neighboring pixels. Images from this source will then display correct blacks and whites without crushing.

3-30 User’s Manual

See Figure 3.7. Adjusting Input Levels Using the Peak Detector

Section 3: Operation

1. Display a 16 level grayscale test pattern from the desired external source, and enter a checkmark in the Peak Detector checkbox.

NOTE: The “Peak Detector” will initially render the grayscale as a uniform gray field before adjustment or extreme crushing.

2. Display one primary color.

NOTE: Selecting Auto Color Enable ensures the correct color is displayed for each setting.

3. For the current color, adjust its corresponding “Black level” slide bar just until a single band of black appears at one edge of the screen. This band represents the first band of the grayscale pattern, which should be 100% black. Do not adjust too far.

4. With the same color still active, adjust its corresponding “Input Drive” slide bar just until a single band of color appears at the opposite edge of the screen. This band represents the last band of the grayscale pattern, which should be 100% white (or the current color, if a certain color is enabled). Do not adjust too far.

5. It may be advantageous to go back and check the black band—adjust the black level slide bar if necessary.

NOTE: Readjusting the black levels affects the gain at this point; only readjust when absolutely necessary.

6. Repeat Steps 3-5 with the other two remaining primary colors. When each primary color shows one optimized black band and white (or colored) band, the input levels for this source are correctly set. Upon exiting the Input Levels menu, the Peak Detector checkbox will clear.

Section 3: Operation

Advanced Image Settings — SUBMENU

Use the Advanced Image Settings submenu to make the adjustments necessary for lesserused but more specialized applications on your projector.

GAMMA TABLE: This control

applies a default video, graphics or simple gamma table or “curve” to your images, controlling the intensity of midlevel colors and producing maximum contrast, brightness and color performance. As shown at right, the graphics curve is a simple power curve while the video curve has a linear segment near black to compensate for increased black levels typical of video signals. A simple gamma curve is a value of 2.2 and is correct for most signal conditions. Although the projector automatically applies either the graphics or video curve according to what type of incoming signal is detected, in some cases you may wish to override this default and use graphics gamma for a video source or video gamma for a graphics source. Alternatively, if neither default is ideal, you may prefer to apply the simple (non-optimized) gamma curve or a user-defined custom gamma curve that has been created externally, named, and downloaded to the projector (requires separate PC-based Arbitrary Gamma

and KoRE Librarian software applications). If any of these special user curves have been installed, their names will appear in the Gamma Table pull-down list.

Keep in mind that any Gamma Table choice sets the related Gamma value (shown in the Image Settings menu) to a 2.2 default, where it can be fine-tuned as desired. Different values (1-3) here indicate that the original gamma table has been adjusted with either the Gamma slide bar or direct key.

3-32 User’s Manual

SELECT COLOR ADJUSTMENT: In “Select Color Adjustment”,

choose an overall color palette for all images. The “Max Drives” factory default simply drives all 3 colors at their maximum level so that they are fully on and cannot be changed. The two other pre-defined color adjustment choices—SD Video and HD Video—apply a color gamut optimized for video sources (standard or high-definition). Alternatively, you can specify a color temperature. This enables the adjacent Color Temperature slide bar and applies its current setting (default = 6500K). If none of the pre-defined “Select Color Adjustment” options or color temperatures suit your application, select one of four color gamuts previously defined by a user (User 1, 2, 3, 4). A “User” option applies a customized color performance in which the user has precisely set the hue and intensity of each color component in the Color Adjustment by X/Y or Color Saturation submenus. It is most often needed with multiple-projector applications. Select the

color adjustment producing the best color accuracy for your application and installation.

To configure a “User” color adjustment (gamut), use either the Color Adjustment by X/Y or Color Saturation submenu.

NOTES: 1) “Color Temperature” defaults to 6500K until changed. All four “User” options default to SD Video unless the user has redefined them. 2) Factory-defined color primaries, which ensure consistent color gamut from projector-to-projector, can be calibrated in the Service menu only. If you suspect alteration, the factory settings can be recovered with selection of “Reset to Factory Defaults?” in the Color Primary Settings submenu within the Service menu (password-protected).

COLOR TEMPERATURE — Adjust to apply a specific and accurate color temperature to

all displays. Color temperatures are expressed in degrees Kelvin (3200-9300K), and utilize different combinations of the projector’s original native color primaries to produce a “coloration” or cast (reddish or bluish) in images—the lower the temperature, the more reddish the cast; the higher the temperature, the more bluish the cast. Note that the slide bar is enabled only if you have a source connected and have selected “Color Temperature” in the adjacent “Select Color Adjustment” pull-down list in the Advanced Image Settings menu.

OPTICAL APERTURE - The optical aperture inside the projector controls the diameter

of the light beam passing through the system. With a fully open aperture (slide bar default of “0”), the maximum amount of light passes through for maximum brightness in your images. Increase the slide bar setting to reduce the aperture diameter and maximize contrast ratio instead. Performance of aperture depends on the lens in use.

NOTE: Optical Aperture also appears in the lamp menu.

FRAME DELAY MONITOR — This slide bar monitors the latency between input and

manual

output. For best results, the bar width and value should remain fairly constant, indicating that timing of input and output frames is locked; the Frame Delay Monitor value should stay within 5-10 lines or so of the Frame Delay setting. If a frame is lost or “dropped”, the bar will move suddenly and the values will change, indicating that the frame input is no longer equal to the output.

NOTE: See separate Using 3D in Mirage manual provided for more information.

User’s Manual 3-33.

Section 3: Operation

FRAME DELAY — Set the number of lines delayed between the input signal and its

appearance on screen, keeping in mind that projector processing always adds one frame of delay to the frame delay setting. For applications such as simulation, where

the feeling of “real time” image response is a priority, a minimum setting is usually preferable. For projectors capable of 3D (stereographic) applications where alternating left-right frames must be synchronized with the corresponding L/R shutters in 3D glasses, a total frame delay setting of two (or multiple of two) may be more useful. If set too high or low, frame locking will not be possible—most sources require approximately 50 lines of delay to ensure frame locking.

time between displayed frames for stereographic 3D images. Higher settings provide more time for shutters in 3D glasses to open/close, ensuring that each eye sees the full display intended for it. Symptoms of cross talk and/or color artifacts can indicate need for adjustment. The Dark Interval range of adjustment depends on the vertical frequency of your source—the higher the frequency, the smaller the range.

stereographic 3D signal locks to the vertical sync output so that signals are synchronized, and 2) whether or not the 3D frames must be inverted, i.e. swapped leftwith-right. The correct setting ensures that the projector’s 3D display of left/right frames is synchronized with the rest of the 3D system components so that the intended eye sees the left/right image data. Select the option corresponding to your 3D source connections and timing, and use only if the Mirage 3D Stereo Sync Cable is connected between the projector’s GPIO port and a server. Keep this adjustment OFF (default) when you are not using the Mirage 3D Stereo Sync Cable.

3D STEREO SYNC DELAY — Set when the L/R frames begin, defining the best

reference point for synchronizing the display with your glasses. Proper adjustment of this delay should eliminate cross-talk and odd colors caused by timing differences between the glasses and the projected display. Use this slide bar only if the Mirage 3D Stereo Sync Cable is connected between the projector’s GPIO port and a server. Slide bar values indicate the number of lines that are delayed.

FRAME LOCK ENABLE — This option allows the projector to control the output frame

timing based on the input signal. The locked option forces (if possible) the output image to be phase locked to the input frames. Rate Matched means that the output runs at close to the input frequency but isn’t locked to it so the output will drift in phase relative to the output. Free Run forces the output to run at a 60Hz frame rate.

MOTION FILTER —

This control is most useful for smoothing out moving images from

interlaced sources. In most cases the proper Motion Filter setting is automatically determined according to the type of incoming source signal. However, if your source is jittery and/or tearing you may wish to “force” a setting to ensure stable processing for this source—if desired, override the default “Auto” setting by selecting the appropriate motion filter:

AUTO: The projector will automatically use the correct motion filter according

to the incoming signal.

STILL: For static images with no motion, such as graphics from a CD.

MOTION: For video images that did not originate from film, or for moving

computer-generated images.

FILM: For video images that originated from film. This will optimize image

quality and stability.

FILM MODE THRESHOLD — This setting determines how sensitively the projector can

detect if an incoming video signal originated from film or not. It should not require adjustment.

DETAIL THRESHOLD — Use “Detail Threshold” to define at what frequency level the

“Detail” control will begin to magnify high frequencies, which adds details back into the image. Raise the threshold to ignore more of these high frequencies, and lower the threshold to magnify more of these frequencies. A setting of “0”, for example, means no noise will be ignored and all will be magnified. An ideal detail threshold is one in which high frequencies that are causing objectionable noise are not magnified when using “Detail”, but frequencies which can help sharpen an overly-soft image are magnified.

For most applications, one of these gamuts will produce accurate and realistic colors from a variety of sources. They can be applied at any time in the Advanced Image Settings menu (“Select Color Adjustment”), and are not adjustable.

User’s Manual 3-43.

Section 3: Operation

DEFINING “USER” COLOR GAMUTS: In some cases, you may find that none of the pre-

defined “Select Color Adjustment” options exactly suit your needs. For example, you may require a unique color gamut (range) for a single projector or application, or you may need to precisely match colors across multiple adjacent displays. In such cases, use the Color Adjustments by X,Y or Color Saturation submenu to define the precise hue of each primary color component (red, green, blue, and white) used to generate the millions of colors produced in displays. You can create up to four custom color gamuts (User 1, 2, 3, or 4) with these adjustments.

Note that the two menus differ only in their user interface, so use whichever menu best suits your needs and application. A color meter can help with adjustments.

• Color Adjustments by X,Y

— Enter known x/y coordinates from the

chromaticity graph.

• Color Saturation

— Adjust color slide bars and judge image color by eye or

meter.

A user-defined color “adjustment” can be applied by selecting it in the Advanced Image Settings menu (“Select Color Adjustment”).

COLOR ADJUSTMENT BY X,Y: Use

this submenu if you want to create, alter or copy a color gamut (i.e., “color adjustment”). Controls in this menu define the precise hue of each primary color component (red, green, blue, and white) used to generate the millions of colors produced in displays. The x/y coordinates for each color define its location on the standard CIE chromaticity graph (see Figure

3.9)—changing either or both of these numbers will change the hue of the color, and relocate the “triangle” for possible colors. For example, changing the x/y coordinates for red may move the

Figure 3.9. Customize Color

color closer to orange or closer to violet, which will in turn affect all displayed colors having a red component. Adjust the slide bars or enter new specific coordinates as desired to define or change up to four “User” color gamuts needed for your environment and applications. Apply at any time in the Advanced Image Settings menu.

PROCEDURE FOR X,Y ADJUSTMENTS: See 3.10, Using Multiple Projectors.

COLOR SATURATION: Use this

submenu if you do not have specific color coordinates in mind and will simply judge color performance by eye or meter. Like the Color Adjustment by X,Y submenu, each color control actually defines new x/y coordinates for that color and changes its hue—it is just a different interface.

Adjust the hue of each primary color (red, green, blue, and white) by using more or less of it in relation to the other colors.

NOTE: A Color Saturation adjustment defines the corresponding x/y coordinates shown in the Color Adjustment by X,Y submenu. These x/y coordinates will remain stable for this User gamut until they are changed again via either menu. Values displayed in the Color Saturation menu, however, will likely fluctuate as you use the projector, and will be different when you return to this menu at some point in the future.

Black Level Blending — SUBMENU

Black Level Blending is a feature that eliminates the differences between black levels when edge blending multiple projectors. The Black Level Blending submenu provides many controls to allow the edges of adjacent images to be smoothly overlapped creating a “seamless” image. Edge blending smoothes white levels, and if edge blending is not in use, Black Level Blending is disabled. Black Level Blending provides a simple solution for uneven black levels, without the need for external hardware, by matching up black level hues with a “target area” hue (the intersection of the center lines), and adjusting the overlaps (edges) surrounding the target area.

NOTES: 1) Refer to section 3.10, Using Multiple Projectors for additional information. 2) There is a centerline (both horizontal and vertical) in the Black Level Blending test pattern. The intersection of these lines is the true center of the projector’s display area. 3) Adjust white levels before adjusting black levels. 4) Blinders are recommended for fixed installations.

Intelligent Lens System (ILS

) — SUBMENU

ILS provides the ability to recall focus, zoom and positioning settings specific to each source input. This allows the projector to display multiple aspect ratios correctly sized and positioned on the same screen. It’s useful when working with a variety of source types that might differ in size and/or aspect ratio since the custom lens settings you’ve chosen for any source will be quickly and accurately applied when you select that source. Place a checkmark in the checkbox to enable ILS. If no calibration has previously been done you may be prompted to do a full calibration. If a motion calibration has been done, you will be prompted to complete a reference calibration. If both calibrations have been done, the checkbox will be checked and ILS enabled. If ILS is enabled, a reference calibration will be done on power up and the lens will return to the saved position of the source that is active at the time of power up or to the position the lens was located when it was powered on. Further adjustments to the zoom, focus and position will be automatically saved for source the selected source. If you switch to a source with different lens settings and switch back, the lens will automatically move to your desired settings upon return. Other sources can be used without using ILS

Freeze Image

Enter a check mark to freeze (stop) an image on a single frame. This diagnostic tool is useful if you need to examine in detail a still version of an incoming image that cannot be “frozen” at the source. For example, in moving images it is sometimes difficult to observe artifacts such as external de-interlacing/resizing and signal noise. Remove the checkmark to return back to normal.

Color Enable

Select which color or colors you want to see. This is useful while working with color temperature, input levels or other special setup parameters. Colors can also be enabled/disabled by entering the corresponding function code listed on the back of the standard remote keypad.

Odd Pixel Adjustment

NOTES: 1) Factory-set and rarely required by user. 2) Source must be >90 MHz.

When using certain RGB sources, you may need to adjust the normal gain or offset of odd pixels in relation to even pixels. This will smooth out very narrow (1-pixel wide) “checks” or vertical stripes that indicate adjacent “on” and “off” pixels. Using the Level Detector simplifies this process (see Figure 3.11):

1. Use an external analog native-sized continuous grayscale test pattern with at least 256-levels.

2. Turn “Level Detector” on.

3. Set “Level Value” to ~200. The image should now be black-and-white (or black-and-one color, if you use “Color Enable” function).

4. Adjust offset. Half of the pixels will move, the other half will not.

5. Adjust until the two transition regions overlap. The stripe of noise will be minimized, defined by the value in the slide bar.

6. Set “Level Value” to ~800. The image should now be black-and-white.

7. Repeat Steps 4 and 5, but adjusting gain.

8. Repeat Steps 3-7 for all remaining colors. Your RGB source should now be OK.

User’s Manual 3-47.

Section 3: Operation

Two sets of values are automatically saved with these controls—one value for Input #1, and one for Input #2 (analog). The current set of values depends on which source is in use. This enables a source to be processed correctly via 2 different inputs.

Figure 3.11. Using “Odd Pixel Adjustment”

NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128 represents no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment eliminates “1 pixel on, 1 pixel off” artifact only, not any type of larger artifacts.

Reserved

No function.

Peak Detector

The “Peak Detector” is a fast method for defining individual input levels, and can improve the accuracy of input levels set by the Auto Input Level function. Enabling the “Peak Detector” activates a special operating mode for detecting only pixels that are considered black or white—all other levels are displayed as a mid-level gray. When used with a 16-step grayscale pattern in which the two black and white bands are known to be at opposite edges of the image, you can watch these isolated areas while adjusting individual black levels and input drives until both bands are just visible. Images from this source will then display correct blacks and whites without crushing or washing out.

NOTE: If using Peak Detector with PIP, both images must have the same color space.

Level Detector

The “Level Detector” checkbox enables specific thresholds for blacks and whites— input levels that fall below a specified Level Value (see below) are displayed as black, and all others are displayed as white. It aids in Odd Pixel Adjustment. To use:

1. Enable “Level Detector” and display a continuous grayscale.

2. Set “Level Value” to near black (such as 200).

3. Adjust Offsets to minimize area of black stripe.

4. Set “Level Value” to near white (such as 800).

5. Adjust Gains to minimize area of white stripe.

Intelligent Lens System (ILS

) Calibration

This option allows you to choose between three types of lens calibrations. Reference calibration determines a reference point that is used as a defined starting position for

relative motion of the lens. All positioning is measured from this reference point. A reference calibration is lost when power is removed from the projector and will occur on every power up as long as ILS is enabled. A motion calibration determines the characteristics of each motor and values are saved in the projector’s memory. If ILS is enabled and a motion calibration has previously been done, the projector will automatically recall these settings from memory when it’s being powered up and a motion calibration will not take place. A full calibration performs both a reference and motion calibration.

3.7 Working with PIP or Seamless Switching

PIP (Picture-in-Picture) and Seamless Switching are independent but related projector features that both utilize two image-processing paths within the projector. In the case of Picture-in-Picture, this double processing enables you to display two different images simultaneously – typically a smaller “secondary” image within a large “primary” background. In a seamless switch, the double processing essentially occurs between displays so that a full image relayed from one source can smoothly transform into a full image from another source. This change can be virtually instantaneous, or slowed as desired so that the current image appears to dissolve or “fade” into the new image.

Options for enabling and controlling PIP and Seamless Switching all reside in the same menu. Note, however, that because both features utilize the projector’s double processing capability, PIP and Seamless Switching cannot be used together. For example, fading a pair of PIP images into a new display from a different source is not possible.

For best PIP or Seamless Switching results, use two different signal types* as defined below. Do not mix two signals of the same type.

Signal Type Description (Input Location)

#1 5 BNCs (RGBHV or YPbPr) #2 DVI - I (analog or digital) #3 Decoded signals (Input 3, Input 4, Composite video, S-Video, or any video

signal via Input 1 BNC connectors or via an analog option card). #4 Analog Option Cards #5 Digital Option Cards #6 Digital Option Cards

* HD interlaced sources are not recommended for the PIP window.

Workin

Other PIP or Seamless Switching tips to keep in mind include:

• When using 2 digital signals or 1 analog and 1digital, each must be ≤ 165 megapixels.

• When using two analog signals, each must be ≤ 90 megapixels.

• Avoid using an interlaced source in the PIP window

• Seamless switching may affect image quality in some cases

NOTE: To control the primary image, access all picture controls through the Main menu. To control the secondary (PIP) image, access picture controls through the Picture-in-Picture and Switching menu.

ASPECT RATIO PRESETS – Choose the desired aspect ratio for your PIP pixels. Use

the “Default” aspect ratio when incoming format has square pixels (most common). This ensures that the resulting PIP image maintains its intended aspect ratio. Use “Anamorphic” for NTSC signals having narrower pixels--this will stretch the pixels horizontally to regain the intended aspect ratio of the PIP image.

NOTE: If the image is already resized at the source it will remain that way in the PIP window. If, for example, an NTSC signal is already set to anamorphic through the Resize and Preset menu it will remain that way in the PIP window. If the NTSC signal is formatted as widescreen at the source, then the image in the PIP window will appear with black bars above and below it.

You can also choose a lamp mode for regulating power and light output, change optical aperture size, and access other read-only information pertaining to past and present lamps.

LAMP HOURS (read-only) shows the number

of hours logged on the current lamp. Whenever you record a new lamp serial number this value automatically resets to “0”, where it begins to log time for the new lamp. This information also appears in the Status menu.

LAMP S/N (read-only) is the serial number recorded for the current lamp. When you

install a new lamp and enter its serial number, the number will appear here.

Section 3: Operation

NOTES: 1) If you change modes over the life of a lamp, the lamp limit you originally expected may no longer be possible. 2) Turning the lamp on and off reduces lamp life significantly, as do other factors. 3) It is recommended that Lamp Limit not exceed the expected lamp life, otherwise a lamp could become dangerously fragile with overuse.

Set which

LAMP MODE you want to use in order to control the

light output. You can choose to run the lamp as bright as possible (i.e., always using maximum power—this is the default upon power up) or you can power the lamp with a specific wattage appropriate for the installed lamp or you can set a specific intensity (brightness) to maintain. Although there are exceptions, generally higher light output or higher power settings can shorten lamp life.

Use the lamp mode that best suits your brightness needs. For example, in a tiled application you may want to precisely match brightness levels between adjacent images—judge by eye and set each individual you want images to be as bright as possible—choose

Lamp Power setting as necessary. Or if

mind that higher lamp power settings can shorten lamp life.

•

Max Brightness: The lamp will always burn as brightly as possible, driven by

setting chosen and cannot be adjusted.

NOTE: The number shown for “intensity” is not the actual lumen output, but rather a correlated value only—1246 may represent 3500 lumens, for example.

Section 3: Operation

To use “Intensity” mode, judge by eye (or use a meter) and set the level as desired for your application. Over time, the projector will automatically increase the power supplied to the lamp as needed to maintain the chosen intensity as closely as possible. This mode is known as “Brightness Tracking” or “LiteLOC”.

HOW LONG CAN I MAINTAIN BRIGHTNESS? Software can maintain your “Intensity”

setting until the required power reaches the maximum rating for the lamp. The lower the setting, the longer it will take to reach this threshold and the longer you can maintain the desired brightness. Keep in mind that once the lamp power reaches its maximum wattage (see “

Power”, above), this tracking is no longer possible. At this

point, the lamp will gradually begin to dim as usual, even though your original “

Intensity” value will still appear in the menu. To resume accurate tracking, reduce the

intensity setting so that the resulting “

Power” value is less than its maximum—the

lower the intensity, the longer it can be maintained.

For example, a 1000-watt lamp can be driven at no more than 1000 watts. To produce desired brightness at the screen, a new lamp would likely need less than this maximum rating—perhaps 812 watts (example only). Over time, however, the lamp will require more and more current in order to generate the desired light, until eventually the lamp wattage reaches its 1000-watt maximum and the lamp power automatically levels off. At this point, the tracking function terminates (i.e., the power level stabilizes) and the lamp will begin to dim normally. Either reduce your “

Intensity” setting or replace the lamp.

Do not lower the “

Intensity” so much that the corresponding “Power” value reaches its

minimum—the intensity setting will be inaccurate and cannot be maintained. For best results in achieving uniform intensity amongst tiled images, choose an “

Intensity”

setting that enables all lamps to operate at less than the maximum number of watts available in your projector but high enough to keep the corresponding lamp power above its minimum. See “

Power”, above.

NOTES: 1) Lamps become more stable over time, thus a specific intensity is more easily maintained as the lamp ages. 2) Intensity can be set only if the lamp is in "Intensity" mode 3) Intensity cannot exceed the output of Max Brightness mode.

Alternatively, you may want to add projectors to a hub on an Ethernet network. See

2.4, Connecting Communications for full routing details.

NOTE: Refer back to 3.6, Adjusting System Parameters and Advanced Controls for

complete information about communicating with multiple projectors.

In a multiple-projector wall, you will likely want to precisely match color and intensity from image-to-image so that the full wall is as uniform as possible. This matching is typically done in conjunction with brightness uniformity and edge blending.

Preliminary Calibration

As a final part of the manufacturing process, all primary colors in the projector are precisely set to pre-established values to ensure that overall color performance is optimized and is as accurate as possible. Upon installation at a site, however, lighting and other environmental factors may slightly change how these colors appear on your screen. While the change is negligible in most cases, you may prefer to recover the originally intended color performance before trying to match colors from several projectors. Or you may be renting a projector in which the colors were corrected for use at its previous site, but are not ideal for yours.

The recommended first step in achieving such consistency is to use a color meter to measure the native primary colors—red, green, blue, and white—as they appear at the screen and record these as Color Primary Settings in the Service menu (passwordprotected) for each projector. On the basis of these new values, which are stored in memory, each projector will then automatically calculate any necessary corrections to reproduce the original factory colors under the current environmental conditions. This essentially calibrates a projector to its surroundings, compensating for factors such as screen type; lamp and/or ambient lighting that can alter the final color characteristics on-screen, and will improve color accuracy and consistency in a group of projectors. It ensures a good starting point for further customizing and matching; however, is not critical for all installations.

User’s Manual 3-57.

Section 3: Operation

To return to the factory-set color primaries, such as when a projector is moved to different site, you must access the Service menu (password-protected). Select the “Reset to Factory Defaults?” option in the Color Primaries submenu. Then repeat the calibration process describe above, if desired, and continue with matching of colors.

Color Adjustment Procedure

Once the Color Primary Settings are calibrated for the site (see above), use the Color Adjustments by X,Y or Color Saturation menu to further refine each projector’s

fundamental colors so that the hue and intensity of each color appears the same from one display to another. Once matched, you will have created a single new shared range of colors or “color gamut” that all of your projectors can produce. This palette—named User 1, 2, 3 or 4—can be applied or disabled for a source at any time throughout a bank of adjacent displays, simplifying both the setup and maintenance of a “seamless” wall.

1. Set up and optimize all projector settings. You can ignore color temperature, since you will be redefining color performance in this procedure, but do optimize each projector in every other aspect. Closely align all screen edges.

2. Assign projector numbers to make communications easier. Use desired keypad.

3. Use the same lamp mode for all projectors, and do the following:

 Set Select Color Adjustment to “Max Drives”  Display a full white test pattern  Adjust lamp power and Optical Aperture until adjacent white fields appear the

same brightness.

4. Display the Color Adjustments by X,Y menus for all projectors. Each menu shows the x/y coordinates defining the “Max Drives” color gamut for this projector. Note the values shown in one (any) of the displays. See Figure 3.13. Or use the “Copy From” function to copy them into a “User” gamut in one projector.

3-58 User’s Manual

5. In each projector, select a “User” color adjustment (1-4) to enable Color Adjustments by X,Y changes. Then enter your recorded x/y values into each menu

(Figure 3.14).

Section 3: Operation

Figure 3.14. Copy X/Y Values into All Projectors

6. In each projector, judge by eye and adjust x/y coordinates slightly in the following manner:

 To match reds, decrease “Red

X” until full field red screens match.

 To match greens, decrease

“Green Y” until full field green screens match.

 To match blues, increase both

“Blue X” and “Blue Y” until full field blue screens match.

NOTE: For speed, enable the “Auto Color Enable” checkbox. Each color coordinate you select will then automatically trigger a full field display of the corresponding color.

Alternatively, use the Color Saturation menu for these adjustments or to fine tune.

NOTE: For speed, enable the “Auto Color Enable” checkbox. Each color coordinate you select will then automatically trigger a full field display of the corresponding color.

These coordinate adjustments move the three color points closer together (see right) to establish a “shared” gamut attainable by all projectors in your group. Adjust only as necessary to ensure that the resulting color palette is as large as possible. When done, you may need to adjust lamp power slightly.

7. All screens should now be color-matched. Apply this new “User” gamut to a

source at any time by selecting it in the “Select Color Adjustment” list accessed in the Advanced Image Settings menu.

Using the Color Saturation Menu for Color Matching

You may prefer to use the Color Saturation menu to match colors across multiple screens. In the three Color Adjustment submenus (Red, Green, Blue—see right), set all main values to 100 and the secondary values to 0. Then judge by eye and adjust the slide bars as needed. Note that adjustments here define new x/y coordinates in the Color Adjustments by X,Y menu.

For best results, use this menu after doing the color adjustment procedure.

WHAT IS BRIGHTNESS UNIFORMITY?

When used to refine screens already matched for their primary colors

Figure 3.15. Color Matching Using Color Saturation Menu

(see Matching Colors in Multiple Screens, above) and overall light output, proper adjustment of Brightness Uniformity can create an exceptionally smooth screen in which:

• no area of the screen appears more red, green or blue than another

• no area of the screen appears brighter than another

• color and light output from one screen closely matches adjacent screens

Although the Brightness Uniformity control can be used for a stand-alone projector, it is particularly useful for setting up and maintaining tiled images that form a cohesive display wall in which the color “cast” and light output appear uniform throughout each image as well as throughout the entire wall. The procedure provided here assumes a multiple-screen application.

3-60 User’s Manual

Before You Begin

Read through the entire procedure before attempting to adjust Brightness Uniformity controls, and keep in mind the following checklist of prerequisites and guidelines:

 ADJUST COLORS FIRST—Always adjust the primary colors as described in

the “Matching Colors in Multiple Screens” procedure (above) before attempting to work with Brightness Uniformity. This ensures that primary colors, color temperature, and maximized light output are all well-matched from one screen to another. These matches are needed before you can achieve good Brightness Uniformity results.

 RUN LAMP FOR 100 HOURS—Light output and Brightness Uniformity can

vary significantly during the first 100 hours of lamp use. For best results with new lamps, either set up Brightness Uniformity after this period, or do an initial setup and re-check at 100 hours.

Section 3: Operation

 SET LAMP POWER—Make sure each “Lamp Power” setting is as high as

possible for your application while still maintaining a good overall match of light output from screen-to-screen. By nature, achieving a uniform brightness will require a slightly reduced overall brightness—this reduction will help ensure that you have enough range of adjustment when examining brightness variables more closely from screen-to-screen, and will help prevent premature “maxing out” when trying to match to a certain color, zone or projector.

 USE A “USER” COLOR TEMPERATURE—Always adjust Brightness Uniformity

for a User color temperature defined when you matched primary colors, and continue to use it for all sources displayed on the wall. Your other color temperatures will not necessarily be matched from screen-to-screen.

 WHITE UNIFORMITY SLIDE BARS—White Uniformity slide bar values may not

reduce to “0”. Each slide bar adjusts overall light output in a specific screen zone, but the value shown represents the current setting for green in this zone. When other “hidden” values (red or blue) are lower than green, during adjustment in the White Uniformity menu their values will reach “0” first, causing the slide bar to stop earlier than expected.

 JUDGE BY EYE OR USE A METER—Good brightness uniformity can be

achieved with either.

Step 1: General Setup

1a) Adjust primary colors (see Matching Colors in Multiple Screens) to ensure

matched overall color temperatures and light output between screens.

IMPORTANT

Double-check that all WHITES and LIGHT OUTPUT are well-matched.

1b) Enable the

Brightness Uniformity

checkbox. This will enable access to the uniformity controls and will apply the settings to your image.

1c) Select the 13-Point test pattern for display.

This pattern provides 9 screen “zones” with 13 targets.

FOR BEST RESULTS: Rather than examining the CENTER of each zone when assessing Brightness Uniformity adjustments focus on extreme EDGES as indicated in the illustration at right.

1d) In either Color Adjustments menu, select a “User” color. Then:

User’s Manual 3-61.

Section 3: Operation

• If you have created a “User 1” color gamut (recommended) for a well-matched wall,

continue to Step

• If you prefer maximum brightness rather than a particular color temperature, select “Max

Drives”.

1e.

IMPORTANT

Do not change User 1 Color Adjustment

in color-matched applications!

1e) In the White Uniformity

menu, set the “Overall” output level to 50.0 and all remaining slide bars to 0.0. This decreases the light output just enough throughout the screen so that any color level can then be increased later as necessary for matching light output from zone-to-zone. Do not exceed 50.0 for “Overall”—a higher level will likely interfere with achieving brightness uniformity and is not recommended.

Ensure that overall light output remains well matched from one screen center to the next. Where necessary, increase or decrease Lamp Power slightly to recover center matches.

Step 2: Adjust Color (level of red/green/blue) in 8 Zones

NOTES: 1) At this point, ignore the brightness of individual zones. 2) Always ignore menu colors.

2a) On each screen, compare the color temperatures in the 8 target zones (4 edges

and 4 corners) to that of the color temperature of the center. Compare using a white field only, and take note of any areas that do not match the center. Also decide if any screen exhibits a more obvious color shift than other screens— begin with this screen in Step

2b) Return to the Brightness Uniformity menu. Beginning with the screen that exhibits

2b.

the most obvious color shift(s), for each edge that exhibits a noticeably different color temperature from the center, select the corresponding Uniformity adjustment menu—Left, Right, Top or Bottom. For example, if any part of the left side is too blue, too red or too green, go to the Left Uniformity menu and adjust the colors (i.e., change their light output) until all portions of the left side closely match the center color temperature. Adjust an edge first (focusing on its center), and then adjust its corners. See Figure 3.16.

3-62 User’s Manual

Section 3: Operation

Figure 3.16. Match Zones to Center Color Temperature

Repeat the color adjustment of sides and corners for each edge of the screen that does not yet match the center (note that each corner is adjustable in either of its two adjacent “side” menus). When done, all areas of a given screen should match. Repeat

2a & 2b for all remaining screens.

Steps

Step 3: Adjust Light Output in 8 Zones

3a) For each screen, compare the light output of each edge and corner to that of the

center. If any of the areas differ, use the White Uniformity menu to match edges

and corners to the center as described below (see Figure 3.17). Begin with the screen exhibiting the most obvious variations in light output.

• Adjust edge White Uniformity first—note that each edge adjustment also affects the rest of the screen slightly. Keep all edges just slightly lower than the center light output rather than matching light output precisely. Otherwise, it may not be possible to brighten the corners (typically the dimmest areas of the screen) enough. I.e., the best uniformity is a compromise between the brightest and darkest areas of the screen.

• Adjust corner White Uniformity last—each corner adjustment affects only this quadrant.

• Repeat for each screen.

e Blendin

Christie Edge Blending is an innovative set of software functions that can quickly and

easily blend white levels along the edges of multiple adjacent projected images to create a single seamless larger image.

What is a Blend?

In simple terms, a blend appears as a gradient strip along an edge of a projected image. It is darkest along the extreme edge of the image, and lightens nearer to the rest of the image (see right).

How Are Blends Used?

In multiple-projector walls, complementary blends between neighboring images can compensate for the extra “brightness” or intensity where these edges overlap. By controlling blend width and other properties, you can achieve uniformity across the group of images. Visible overlaps will disappear:

Figure 3.18. Edge Blending Concept

For best results, use the same projector model and type throughout your display wall. In addition, avoid high-gain screens whenever possible—the optical performance of such screens demands minimal image offset, thus projectors must be located very close to one another.

Edge blending software controls are located in the 2-page Edge Blending submenu— access via Configuration menu, then go to the Geometry and Color menu and select Edge Blending. The More option opens the second page of the Edge Blending submenu.

Main Functions

Use Edge Blending controls to set the precise width, shape and midpoint you need to blend overlapping edges together smoothly.

 Blend Width determines how much area is used for blending along an

overlapping edge. Slide bar values represent the number of 8-pixel steps used for the blend. For example, a setting of “3” creates a blended edge 24 pixels wide. A setting of “0” signifies no blending. For best results in most applications, use a blend width of 16-48 steps (128-384 pixels).

Ranges: 0-80 horizontal, 0-60 vertical.

3-64 User’s Manual

 Blend Shape determines the rate of

roll-off across the blend width, i.e. how quickly the white levels across the blend change from light and dark. Increasing the Blend Shape setting accelerates the rate of change at both extremes so that less of the region appears midgray (see Figure 3.19). Decreasing the Blend Shape setting slows the rate of change so that more of the region appears mid-gray. For most applications, this subtle control is best left close to 50.

 Blend Midpoint determines the white

level at the blend midpoint (the point equidistant between the beginning and end of the blend). Increasing the Blend Midpoint setting creates a blend that appears brighter than the rest of the image. Decreasing the Blend Midpoint setting creates a blend that is darker than the rest of the image. A setting of 50 means the midpoint is approximately 50% black—for best results in most applications, keep fairly close to this default.

Section 3: Operation

 Show Blending Overlap turns your

defined blend width area to solid gray so that, if needed, simply overlapping the gray bars can seamlessly align two adjacent images. Toggle the Show Blending Overlap off to reactivate the blend effect.

Other Functions

For convenience, the Edge Blending submenu also includes related options for enabling a specific color and/or test pattern, or for working with colors or the lamp. Such functions duplicate those provided elsewhere in the menu system.

User’s Manual 3-65.

Section 3: Operation

Edge Blending Procedure

NOTES: Before attempting to work with edge blending software functions, you must

1) physically align the projectors/images by correctly overlapping the displays from

your intended external source, and 2) Match colors and Brightness Uniformity.

IMPORTANT

For a shared edge, all Blend procedures and settings

should be identical on BOTH projectors.

1. Start with 2 projectors. Display full white field test pattern from both.

2. In the Edge Blending submenu, enable Edge Blending by entering a checkmark in the top checkbox.

SET STARTING POINTS FOR ADJUSTMENT:

 Set all blend widths to 0.  Go to “More” and set everything in the Edge Blending (2) menu to 50.

Figure 3.21. Set Starting Points for Each Projector

4. SET BLEND WIDTH: On one projector, increase the Blend Width for an overlapping edge (for example, if the projector’s image is on left, its right edge overlaps the adjacent image—adjust Right Blend Width). Use the same setting on the second projector for this shared edge.

5. Re-adjust width (both projectors) until the overly bright band at the midpoint of the overlapping blends disappears or just changes to very light gray. For the shared edge, use the same Blend Width setting on each projector. If the “best blend” appears to be between two settings, choose the wider setting for both projectors.

CHECK BLEND: If the blended region appears too dark or light in relation to the rest

of the image:

 Increase Blend Midpoint in both projectors to “lighten” the overall blend,

decrease to “darken” the overall blend.

 Adjust Blend Shape in both projectors to fine-tune change the amount of mid-

gray intensity (as opposed to black/white) in the blend.

7. Repeat with remaining projectors / overlaps.

8. Check completed display wall with the desired external signal.

9. Adjust mechanical alignment if necessary to maintain perfect pixel-on-pixel alignment over time.

3-66 User’s Manual

Black Level Blendin

Section 3: Operation

In applications where you are projecting only white or light images, the Blend Width may be slightly higher—set according to how much overlap you have between images. Use the following as a guide (examples show overlapping width only—values for overlapping height will differ):

 Recommended overlap is 12.5% - 25%

Similar to Edge Blending, Black Level Blending allows you to adjust the black level

hues of multiple adjacent projected images to create one large seamless display. Edge blending must be enabled in order to use the Black Level Blending features.

Black Level Blending Procedure

NOTES: 1) Adjust white levels before adjusting black levels. 2) The zones in BLB menu correspond to the Edge Blend zones. If a given Edge Blend zone width is set to 0 (i.e. no blend on that side) then the corresponding BLB zone is disabled. It only becomes accessible when that Edge Blend zone is active.

1. Start with 2 projectors. Select the black test pattern for both projectors from the Geometry and Color submenu.

2. In the Black Level Blending submenu, enable black blending by putting a checkmark in the checkbox for each projector.

3. Working with one projector at a time, use the center brightness slide bar to adjust the center brightness (brightness of the non-blended region) so that the center intensity matches that of the brightest blended region (the center of all images when blending a 2x2 display is the target area).

4. Use the following three color slide bars, Black Red Level, Black Green Level and Black Blue Level, so the black hue of each projector matches.

5. You can choose which of the next four options, Top, Bottom, Left, Right, to use depending on which edge of the projector you are working with has been edge blended. The blend width can be adjusted to line up properly but by default it corresponds to the edge blending setting determined for that edge.

User’s Manual 3-67.

Section 3: Operation

3.11 Remote Control of the Projector

6. The brightness and black hues of the blended region can be adjusted in more detail in case fine-tuning is needed (may be only necessary for blending a 2x2 projector display because of blending differs for the sides and center).

NOTES: 1) The menu options vary depending on the Edge Blending parameters.

2) You may need to re-adjust the black level hues following the overlap

adjustments on each blended edge. 3) When adjusting six or more projectors, you need to ensure that the hue and brightness of each target area is matched at closely as possible.

As an alternative to using a keypad, most projector functions can be controlled remotely, typically at a controller such as a PC, via 1) simple bi-directional ASCII messaging on an Ethernet or serial communication link or 2) a web interface or “ChristieNET” on an Ethernet network. Using a PC interface can also prove to be useful in instances where extreme warping is applied and the menu items become illegible and hard to navigate.

VIA ASCII MESSAGING — Connect a serial link between your controller and the RS232

or RS422 port (recommended), or open an Ethernet socket (i.e., Telnet) between your controller and the valid projector address. Valid ASCII codes and messages are documented in the Christie Serial Communications document available at the Christie website.

VIA WEB INTERFACE — Connect your PC to the projector’s Ethernet port. In your web

browser (Internet Explorer, for example), enter the IP address of the projector you wish to control. This will start a password-protected ChristieNET application—enter the factory default “

ccm7” login and password to open the program. If the projector is

powered up, you can access assorted menu options and slide bars.

Repeat for remaining networked projectors as desired. Keep in mind that multiple units can be controlled from one PC, but each unit will be in its own ChristieNET interface (web browser) at the PC. Likewise, you can make up to five separate web locations to a single projector.

The default login provides access to security settings, where you can define other users with the same or fewer rights. Use “unlimited” rights for most applications. For all logins, the Service menu is still protected with its own password.

NOTES: 1) Any proxy server settings that interfere with this type of link should be disabled for using ChristieNET. Disable through Internet Explorer’s < Tools> <Internet Options> <Connections> <LAN Settings>. 2) Your PC must be Javaenabled to v1.4.2 or higher to run ChristieNET. 3) Depending on your projector model, certain controls provided through ChristieNET are non-functional.

3.12 Error

Conditions

Section 3: Operation

Occasionally the projector will encounter an error condition that can interrupt normal operation. Such a condition can be caused by a simple invalid keypad entry, an input signal error (most common) or a system error. The manner in which users are to be notified of error conditions is set in the Menu Preferences menu:

Note that a two-digit error code appears in the status LED display window located beside the built-in keypad at the rear of the projector. Normal operation is indicated by the “0n”status code.

Invalid User Entry

A keypad entry not recognized by the projector triggers a short on-screen error message identifying the problem. For example, if you specify a channel number that is not available, the message “Invalid Channel will appear. Or if you try to enter the wrong password, you’ll see “Invalid Password”. Press

Exi t

to clear the

message, and try again.

Input Si

nal Errors '

NOTE: On-screen display of “Invalid User Entry” messages cannot be disabled, even if Display Error Messages has been set to “Off”.

An input signal error message occurs if you are in presentation level (i.e., there are no menus present) and have selected an input on which the projector detects a problem. While menus remain operational and any key press will temporarily remove any displayed error message, you must resolve the signal problem in order to permanently eliminate the message.

No Signal

The message "No signal" occurs when there is no source signal detected at the selected input—both HSYNC and VSYNC are inactive and the screen background is black. Connect or correct the signal, or try another input.

Bad Sync

The message "Bad Sync" occurs when HSYNC or VSYNC are active but the signal cannot be displayed. Such a condition occurs when only one of the two sync signals is present or when either sync signal is unstable or of the wrong frequency. Correct the signal or select another input.

Other Signal Error Messages

In addition to the common "Bad Sync" and “No Signal” errors, you may encounter a signal error message indicating that HSYNC and/or VSYNC are either too fast or too slow. When such a message appears, check the frequencies shown in the Status menu. If they are correct, the projector does not recognize the signal. On some PCs you may be able to change the settings to generate a compatible signal. If the frequencies shown in the Status menu are incorrect, check the cabling to see where the problem might originate.

When the projector encounters a system malfunction, either a System Warning message or a System Error message may appear. Both types of messages are accompanied by a numerical error code on the status LED display. A system malfunction can be cleared with

Exi t Exi t

from presentation level, but may indicate

the need for service by a qualified service technician.

NOTE: System messages appear on-screen only if Display Error Messages has been set to “Screen” or “All”.

System Warnings

A system warning indicates that a system malfunction has been detected (see Status LED Codes, below). A system warning message replaces any input signal message

and disappears when the input signal status changes. While the projector will remain operational, the message indicates the presence of a potentially serious problem that should be investigated. You can press

Exi t Exi t

to remove the message, but for best results you should reset the projector—power the projector down and up again with the

(power) key.

System Errors

A system error message indicates that a serious malfunction has been detected and must be investigated as soon as possible (see Status LED Codes, below). The projector will no longer operate and must be reset—power the projector down and up again

with the

(power) key.

The Status LED Codes

If the status code display on the back of the projector shows one of the following values, you have encountered a likely system error requiring the attention of a qualified service technician (see System Warnings and System Errors, above). Acknowledge and clear the error with

Exi t Exi t

from presentation level, or try resetting the projector by powering it off and on again, cooling when necessary. Consult Table 3.5 and contact your dealer if the problem persists.

The specific code number identifies the source of the error detected, and is particularly useful in cases where the projector is far away. For example, the code “27” means the lamp could not be turned on. Error codes for this projector are listed in Table 3.5 below.
