injury.

1.2 General Precautions

The projector is a class 2M source of visible and invisible

LED radiation. Directly Viewing the LED output with certain
optical instruments (e.g. eye loupes, magnifiers and
microscopes) within a distance of 100mm (3.94”) may pose
an eye hazard.

The projector is a class 2M source of visible and invisible LED radiation.

Directly viewing the LED output with certain optical instruments (for
example, eye loupes, magnifiers and microscopes) within a distance of 100
mm may pose an eye hazard.

Power should always be disconnected from the illumination module before

servicing, to avoid the possibility of inadvertent exposure to visible and
invisible LED radiation. Directly viewing the illumination module optical
output through certain optical instruments (for example, eye loupes,
magnifiers and microscopes) within a distance of 100mm may pose an eye
hazard.

Disconnect the AC cord before disconnecting the light module from the

Projector Head Module (PHM).

2Installation and Setup

This section explains how to install, connect and optimize the projector display.

2.1 Installation Considerations

• Ambient temperature must stay below 40°C (95°F). Changes in temperature can cause drifts in the projector
circuitry, which may affect performance. Keep the projector away from heating and air conditioning vents.

• Keep the projector away from all devices radiating electromagnetic energy. For example, motors and
transformers, slide projectors, speakers, power amplifiers and elevators.

• Use an optical mirror for rear screen installations to shorten the optical light path and use less space in the
projection room. For more information about projector installations, see 2.1.5 Installation Types.

2.1.1 Ventilation

NOTICE: Caution do not obstruct the air exchange to the projector.

The projector vents provide ventilation, both for intake and exhaust. Do not block or cover these openings. Do
not install the projector near a radiator or heat register, or within an enclosure. Make sure there is a minimum
clearance of 25cm (10”) on the left, right, top and rear sides of the projector.

2.1.2 Screen Size and Type

Screens with an aspect ratio of 16:10 are recommended for use with these projectors. To fill a screen with an
image, the aspect ratio of the screen must be equal to the aspect ratio of the image.

Diffused and optical screens are best suited for rear screen installations. A diffused screen has a surface which
spreads the light striking it. Purely diffused screens have a gain of less than 1. Optical screens take light from
the projector and redirect it to increase the light intensity at the front of the screen.

2.1.3 Ambient Lighting

The contrast ratio of projected images is reduced when light directly strikes the screen. Eliminate all stray light
sources from the viewing area.

Section 2: Installation and Setup

2.1.4 Lifting, Transporting and Mounting

Mount the projector to a sturdy, flat surface that fits the entire projector.

Use all four mounting points to secure the projector to the surface.
Maintain a minimum clearance of 25cm (10”) around the projector, called a

“stay out zone”, for air circulation and clearance for cable connections to the
input panel. Insufficient stay out zone clearance can cause the projector to
overheat during operation and/or place undue stress on source connections.

The projector should be lifted by 2 people. Use a stable cart to transport the projector. Refer to the drawings
given for your specific projector model for the mounting hole location and other technical information and
restrictions which may be useful during
installation.

• Requires a separate room or enclosure.

• Higher installation cost.

• Requires a separate room.

• Higher installation cost.

• Access to the projector is limited.

• Requires a separate room or enclosure.

• Higher installation cost.

• Complex installation.

• A diffused screen has a surface, which spreads the light striking it. Purely diffused screens have a gain of less
than 1.0. The 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 sitting within the
viewing cone.

Lens Focus Adjustment for Fixed Lenses

This section describes best practices for lens focus adjustment of the 0.64:1 WUXGA lens
(PN: 002-120444-02) and the 0.75:1 (PN: 002-120415-01). The lenses have focus and field curvature
correction to sharpen the projected image. Failure to properly adjust lens focus results in an image that is not
uniformly focused and contains geometric distortion.

1. Loosen the main locking screw and the focusing screw.

2. Adjust the focusing screw for best focus in the image center.

3. Loosen the field curvature locking screw and adjust the field curvature focusing ring to sharpen the image
corners. Refer to the image below as an aid to gage the specific preset for your screen size.

4. Finally the focus screw should be "tweaked" for best overall screen focus.

5. Although it is not necessary, you may want to retighten the main locking screw. NOTE: Use a maximum of

4in.-lbs to tighten the main locking screw.

2.2.3 Calculating Throw Distance, Position and Mount Projector

Throw distance is the distance measured from your projector to the screen. This calculation determines if there
is enough room to install your projector with a desired screen size and if the image will be of the right size for
your screen. To estimate the throw distance take the horizontal width of the screen and multiply it by the lens
throw ratio. The result determines approximately the distance the projector should be positioned from the
screen to project a focused image large enough to fill the screen. For example, using a 1.2:1-1.6:1 zoom lens
set at its widest (1.2:1) throw ratio, throw distance would roughly be 1.2 x screen width.

IMPORTANT: Use the lens and screen size to calculate the precise throw distance. Due to lens manufacturing

tolerances for lens focal length, actual throw distance can vary
throw ratio.

Projector Vertical and Horizontal Position

The projection lens and the screen type determine the vertical and horizontal position of your projector in
relation to the screen. Ideally, you should position the projector perpendicular to the screen to make the image
appear rectangular instead of keystoned (trapezoidal). You can offset vertical position of the image (move it
above or below the optical axis) by adjusting the lens mount. The type of projection lens you install determines
the amount of available vertical offset. Vertical offset can be expressed as the percent of half the image height
or the number of pixels of shift from lens center.

NOTES:

1)

Offsets are subject to ±7% centering tolerance.

2) % offset is defined as:

The horizontal position of the image can also be offset (moved to the left or right of optical center) by adjusting
the lens mount. The amount of horizontal offset available depends on the lens installed and if the image has
already been vertically offset. Horizontal offset can be expressed as the percent of half the image width or the
number of pixels of shift to one side of lens center.

Section 2: Installation and Setup

Mounting the Projector

NOTICE: Use only the CHRISTIE approved projector mounts designed for your projector. Refer to the

installation instructions and safety guidelines provided with in the kit.

There are several methods for mounting the projector. In typical front and rear screen installations the projector
can be mounted to a secure and level surface. The projector can be mounted in any orientation without
affecting performance.

2.3 Connecting Sources

All source connections are made to the input panel of the Electronics Module. Each input is labeled for easy
identification. Using the correct cable(s), connect your source. An interconnection label is available for
reference on the light module. Sources are connected to the Input Panel located at the top of the EM. The Input
Panel has slots for 1 image processor board and up to 4 input cards, and comes standard with 2 slots populated.
The input cards are hot swappable; they can be plugged in and out while the projector is running. The image
processor should only be replaced when the projector is OFF or when it is in STANDBY mode.

The video card that is installed in your projector determines the type of video source you can use. These video
cards are supported:

• High-Definition Multimedia Interface/Twin HDMI (High-Definition Multimedia Interface)

• Analog BNC

• Dual SD/HD-SDI (Serial Digital Interface)

• Dual Link DVI

•Video Decoder

These cards slide into any of the available option slots. One or more of the option slots may be used with any
combination of option cards, including multiples of the same card type. One input is active on any card at a
single time, except the Dual HDMI and Dual SD/HDSDI cards, which support up to 2 active signals on 1 card.

NOTE: Use only high-quality shielded cables for all connections.

LEDS

LEDs are located on the faceplate of each input card and indicate the following:

• Power ON - Green

• Signal Valid - Green

• Signal Invalid - OFF

DVI Digital Video

Use the DVI-I connector to connect either analog or digital video devices to the projector. Use a cable with
DVI-I connectors at both ends to connect devices that transmit digital and analog video signals such as satellite
receivers and digital cable TVs.

NOTE: For true digital output from devices that transmit digital signals,

connect to the DVI-I connector.

Dual Link Digital Video Input (DVI) Input Card

This card accepts a maximum 330MHz DVI-D or 165MHz HDMI signal via the DVI-I connector without
High-Bandwidth Digital Content Protection (HDCP) and analog video signals over the DVI-I or 15-pin VGA
connector. The module can simultaneously support a digital signal on the DVI input and an analog signal on
the VGA port; however, it does not support 2 analog signals at the same time. There are 4 LEDs on the module
faceplate. PWR indicates power is applied and the card is initialized, and the other 3 LEDs on the right-side of
the corresponding connectors indicate that a valid signal has been detected.

Twin HDMI Input Card

This card accepts 1 or 2 HDMI inputs, and can route one or both inputs to the card’s outputs without High­Bandwidth Digital Content Protection (HDCP). Any input from any card can be looped out of this card. The
output label ‘1-OUT’ loops out the main image being displayed on the projector. The output labelled ‘2-OUT’
loops out the image displayed in the picture in picture (PIP). Any input from any optional input card can be
looped out of this card. There are five LEDs on the module faceplate. The PWR on the left side indicates
power is applied, and that the card is initialized. The LEDs to the right side of the corresponding connectors
indicate that a valid signal is detected. In the case of the outputs, the LED indicates a signal is currently being
looped out.

Analog BNC Input Card

This card accepts several types of sync modes. In 5-wire sync mode all 5 BNC connectors are used. If H and V
connectors are swapped, this card will still operate normally. An analog graphic source such as a VGA from a
PC can be connected. The card can operate in 4-wire sync mode, which accommodates 4-wire RGBC sources.
The composite sync cable can be connected to either the H/C BNC or the V BNC. The card supports 3-wire
RGB or YPBPr sync modes, sometimes called sync-on-Green (SOG). In this mode the H/C and V connectors
are not used. The sync is connected to the Green/Y BNC connector. This card offers no loop out capability.
There are 2 LED’s on the module faceplate. PWR indicates power has been applied and the card is initialized,
signal indicates a valid signal has been detected.

Dual SD/HD - SDI Input Card

This card accepts both standard-definition (SD) and high-definition (HD) serial-digital-interface (SDI) signals
from one of two standard-definition (SD) or high-definition (HD) SDI sources. Both single-link HD and dual­link HD signals are accepted. The card has two SD/HD-SDI outputs, each of which is “loop through” for its
respective input. There are three LEDs on the module faceplate. PWR indicates power has been applied and the
card is initialized, and the two signal LEDs indicate a valid signal has been detected on the respective input.

Video Decoder Input Card

This card accepts and decodes standard definition (SD) video. This includes CVBS (composite video), S­Video, and component sources. This card supports as many as six video signals, four of them on BNC
connectors and two on four-pin mini-DIN connectors. Each mini-DIN connector accepts one S-Video signal.
The first BNC accepts composite video (only), while the remaining three BNCs can be grouped to allow one of
the following combinations:

• 3 CVBS sources on 4, 5 & 6

• 1 CVBS source, 1 S-Video source: Luma (Y) connected to 4 (Sy) and Chroma (C) connected to 6 (Sc)

• 1 YPbPr source: component signal on 4(Pr), 5(Y) & 6(Pb)

The video decoder input card has 8 LED indicators. The PWR LED indicates that the module is installed
properly, and has been successfully configured. The YPbPr LED indicates that a valid component signal has
been detected on inputs 4, 5, and 6 (Component input grouping must also be selected in the projector’s menu ­see Section 3 Operation. The remaining LEDs are each associated with one of the inputs and indicate a valid
signal has been detected on that input.

2.8 Setting up the Image

2.8.1 Adjusting the Projection Lens

NOTICE: Lock lens adjustments to prevent unnecessary tampering.

Loosen the adjustment locks on the lens barrel before making adjustments.

2.8.2 Adjusting Image Geometry and Optical Alignment

Only perform image alignment once the projector is fully assembled and powered up in its final location. Basic
image alignment ensures the image reflected from the DMD is parallel to and well-centered with the lens and
screen. This initial optical alignment is the foundation for optimizing images on the screen, and must be
completed before final boresight adjustments. Before beginning, ensure that the projector is properly
positioned relative to the screen.

Basic Optical Alignment Procedure

1. Display a test pattern: Appropriate for analyzing image focus and geometry, such as the “framing” test
pattern showing the cross-hair centered across the image. Press the Test key on the remote keypad.

2. Coarse focus: Do a quick preliminary focus and (if available) zoom adjustment with the primary lens. Do
not worry about consistency across the image at this point, just center focus. It is good practice to have the
zoom adjustment collar and the focus adjustment collar in the center of its range.

3. Center the image in the lens: Holding a piece of paper at the lens surface, adjust offsets as necessary until
the image is centered within the lens perimeter. A full white field works best for this.

4. If necessary, center the image on the screen: If the projector is mounted off-center to the screen axis,
then offset the lens as much as required. Aim the projector over slightly towards the center of the screen,
but use caution, as too much tilt will cause excessive keystone distortion. Lens offset will not.

5. Re-check side-to-side leveling: With the framing pattern on screen, double-check projector leveling so the
top edge of the image is parallel to the top edge of the screen.

6. Throw distance: Ensure that the projector is positioned in the throw distance range for the lens in use.

3. If boresight is required, see Figure 2-8 to understand how the adjustment screws on the lens mount affect
the corresponding cross-hairs on the test pattern.

4. Use a 5mm Allen key to loosen the three locking setscrews on the lens mount, see Figure 2-9.

NOTE: The setscrews must be backed out several turns, so that they do not contact the inner lens mount

plate.

Figure 2-8 Cross-Hair Pattern Figure 2-9 Screw Locations

5. Fine tune the focus of cross-hair pattern I by adjusting the appropriate capscrew, see Figure 2-9. Adjust
until the cross-hair image is in focus with minimal flare.

6. Adjust cross-hair pattern II, by adjusting the appropriate capscrew, see Figure 2-9. Adjust until the cross­hair image is in focus with minimal flare.

7. Adjust cross-hair pattern III, by adjusting the
appropriate capscrew, see Figure 2-9. Adjust until the
cross-hair image is in focus with minimal flare.

8. Repeat steps 5, 6 and 7 as required until all three cross­hair patterns are in equal sharp focus. If the boresight is
acceptable, see Step 11. If the boresight does not appear
to be converging to an acceptable level of image quality
or if the lens will not focus over the correct range of
throw distances, then the boresight requires coarse
adjustment, see step 9.

9. The original factory boresight can be recovered
approximately by positioning the 3 setscrews, see
Figure 2-9. Position the setscrews flush with the front face of the lens mount plate and in contact with the
inner lens mount plate, see Figure 2-10. This may require adjusting both setscrews and capscrews.

10. If further action is required. Repeat step 2.

020-100774-01 Rev. 2 (4-2012)

11. Lock the set screws and re-check the boresight quality. Tighten the setscrews enough to ensure they will
not shift.

12. When the image is focused, lock adjustments in place by tightening the adjustments until just tight.

2.10 System Integration - GPIO Connector

The General Purpose Input-Output (GPIO) connector located on the Mirage WU-L projector input panel is
used to enable control of stereo function.

GPIO and External Devices

If you want to use GPIO to interface external I/O devices to the Mirage WU-L projector, you will need to have
a custom adapter made. Seven GPIO pins on the 9-pin D-Sub GPIO connector are configured through RS232
commands. The other two pins are reserved for ground and power. See GPIO Pins for pin identification. The
cable required for connecting the external device to the projector GPIO connector, whether a standard serial
cable or a custom one, must be compatible with the external device.

Table 2.8 GPIO Pins

4GPIO 3

5 Ground

6GPIO 4

7GPIO 5

8GPIO 6

9GPIO 7

The GPIO connector can be configured to automate any number of events using the serial command code GIO.
Each pin is defined as either an input or output depending on the desired outcome. In general, configure the pin
as an input if you want the projector to respond to something the device does and as an output if you want the
external device to respond to an action taken by the projector. For example, configure the pin as an output if
you want the lighting in a room to automatically dim when the projector is powered ON. By using the GIO
command, you can also set the state of each pin as high or low. By default, the state of each pin is high. The
voltage applied to pins in the high state is + 3.3V. See (GIO) General Purpose Input/Output, on page D-29.

2.11 Projection Lenses, Lens Mount and Other Features

Using the lens cap when transporting the lens avoids scratching and
damaging the lens.

The Mirage WU-L projector includes a lens mount that allows lens control and adjustment: vertical and
horizontal offsets, zoom and focus. The lens mount can be fitted with any one of the available optional lenses –
see Section 7 Specifications.

• Zoom and Focus – Adjust zoom to fit the displayed image on the screen and adjust focus to improve the
clarity of the image.

• Lens Offset – The lens mount allows vertical and horizontal offset of the displayed image.

• Shutter – Standard on all models, the shutter allows you to turn the screen absolutely black when in the
“Closed” state. A WHITE shutter state allows you to view menus and images if RGB brightness is set to 0.

2-20 Mirage WU-L User Manual

020-100774-01 Rev. 2 (4-2012)

2.12 Cleaning the Lens

Check periodically. A small amount of dust or dirt on the lens has minimal effect on image quality. To avoid
the risk of scratching the lens, clean only if absolutely necessary.

Dust:

1. Brush most of the dust from the lens with a camel-hair brush or blow dust away with a dust-free blower.

2. Fold a microfibre cloth smooth and gently wipe remaining dust particles from the lens. Wipe evenly with
the smooth portion of the cloth that has no folds or creases. DO NOT apply pressure with your fingers - use
the tension in the folded cloth itself to collect dust.

3. If significant dust is still bound to the surface, dampen a clean microfibre cloth with coated optics cleaning
solution (damp, not dripping). Wipe gently until clean.

Fingerprints, smudges, or oil:

1. Brush away most of the dust with a camel-hair brush and/or blow away using a dust-free blower.

2. Roll a lens tissue around a swab and soak it in coated optics cleaning solution. The tissue should be damp,
but not dripping.

3. Gently wipe the surface using a figure-8 motion. Repeat this motion until the blemish is removed.

3 Operation

See Safety Warnings and Guidelines in 5 Maintenance.

This section describes the controls and switches used for basic projector operation once it is properly installed,
aligned and configured by a Christie accredited service technician. You can access projector controls and
settings with the IR remote, or with a laptop using the web interface. This chapter focuses on the use of the IR
remote, and the projector menus. For information about accessing the same functionality through the web
interface, see Appendix B: Web User Interface.

3.1 Using the IR Remote

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

directly into the beam of the laser.

The standard IR remote can be used as a wired or wireless control. Under optimal conditions, the wireless
keypad can communicate with a projector over a 100 foot distance. In wireless mode, the standard IR remote
communicates with the projector with a battery-powered infrared (IR) transmitter.

Use the standard IR remote the same way you would use a remote control supplied with a TV or DVD player.
When pressing a function key, direct the standard IR remote toward the projector’s front IR sensor. The IR
sensor on the projector will detect the signal and relay the commands for internal processing. A laser pointer is
built into the standard IR remote.

Keep these guidelines in mind:

Section 3: Operation

• Press keys one-at-a-time; there are no simultaneous key combinations required.

• NOTE: To use Power, Shutter, and OSD functions, press the appropriate button and then press the

to switch ON or the
seconds, or press it twice quickly.

• Arrow keys are held down for continuous adjustment/movement in the related key direction.

• NOTE: In serial networks, pause briefly between adjustments to make sure that more distant projectors can

“keep up” with the commands. If you press a key while the projector is still responding to the previous
action, such as during power-up, the second key press may not take effect.

•See 3.1.1 IR Remote, on page 3-2 for the description of those keys provided for the standard IR remote

3.1.2 Wired Remote

You can convert the standard IR remote into a wired remote using the optional cable. Connect one end into the
standard IR remote, and the other to the XLR connector labeled Remote on the Electronics Module. The
wired remote is recommended when the lighting conditions are unsuitable for proper IR transmission.

To use the wired remote, make sure that wired remote support is enabled on the projector the remote is
connected to: Main Menu > Configuration > Communications > Wired Keypad Enabled.

To use the wired remote to control multiple projectors in an ArrayLOC network, ensure that wired remote
support is enabled on the controlling projector, and make sure that key synchronization is enabled on the
controlling projector and on all the receiving projectors: Main Menu > Configuration > ArrayLOC >
ArrayLOC Configuration > Synchronize Keys, Test Pattern, Color Enable.

NOTE: A wired remote control does not require batteries unless you need to use the laser pointer.

3.1.3 IR Remote Commands

Specific keypad commands are explained in 3.1.1 IR Remote, on page 3-2.

The projector is a class 2M source of visible and invisible LED radiation.

Directly viewing the LED output with certain optical instruments (for
example, eye loupes, magnifiers and microscopes) within a distance of 100
mm may pose an eye hazard.

The Best Auto Setup will be obtained under the following conditions:

• Input levels: It is best to have an image with saturated (very bright) colors.

• Phase: High contrast edges are needed.

To determine the active window size:

• Video images should have whites and blacks in the image.

• Wide range video images should have content (including white) that extends to all edges of the image.

Contrast

Changes the level of peak white in your images. Use the

LEFT/RIGHT arrow key 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 light areas do not become fully white (i.e., “crushed”). Conversely, low contrast causes dim images.

Bright

Increases or decreases the black level in the image. Use the

LEFT/RIGHT arrow key until you reach the desired

level of brightness. For best results, start high and decrease so that dark areas do not become fully black (i.e.,
“crushed”). Conversely, overly high brightness changes black to dark gray, causing washed-out images.

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 values used in grays. Unlike brightness and contrast controls, the overall tone of an
image can be lightened or darkened without changing the 2 extremes and your images will be more vibrant yet
with good detail in dark areas when using the Gamma control. The nominal setting for Gamma Correction of 0
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, increase the gamma correction setting to compensate.

3.3 Using Inputs and Channels

The projector allows you to define, store, and recall up to 99 different channels (customized setups or
configurations) for a variety of inputs. Each physical source connection (i.e., input at the projector) can have
several different channels associated with it:

• Slot refers to an input card installed in the projector. There are 4 input card slots.

• Input refers to both the physical connector on the input card and to the media source connected to it. Each
Input card can have one or more inputs.

• Channel refers to the setup parameters for a media source input. The parameters include the slot and input,
input type, and input resolution.

NOTE: See 2.3 Connecting Sources for a full explanation of how to connect sources to the projector.

3.3.1 Inputs

An input is a input source physically connected to the projector. Input describes the source signal and the input
slot (1-4) to which it is connected.

Switching Inputs

To select an input using the IR remote:

• Press the
each of the 4 input slots. See Figure 3-8. The currently selected input for the main image is highlighted.
Scroll UP or DOWN through the list. Press

Input

Signal

Type

Horizontal
Frequency

i-Interlaced

p-Progressive

With any of these methods, the image displays 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,
automatically displaying an image according to default settings for that 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 (Creating a New Channel on

page 3-11). Using one of the input or slot keys will automatically recall this channel—and all its setup

parameters—and will update the display accordingly. If more than one channel exists for the input, the image
displays according to the setup parameters for the first channel with matching characteristics.

3.3.2 Channels

A channel is a collection of measurements, locations, and
parameter settings that tailor the display of a signal to your
specific needs. Since input 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 input source. For example, the display settings you
choose for a VCR source may be very different from those you
choose for a high-resolution computer source. Once you have
adjusted a display parameter, such as pixel tracking or contrast,
all current settings are collectively stored in the projector's
memory as a unique 2-digit channel, such as 09. You can have
numerous distinct channels available for the same input, any of
which can be selected by using the
the 2-digit channel number. Shown in Figure 3-6 is a sample list of channels available for Main Channel 03.

Section 3: Operation

CHANNEL key, followed by

NOTE: The CHANNEL key may display a channel list or not, depending on what you have defined for
“Display Channel List” (see Menu Preferences on page 3-31 discussed later in this section).

In order to access channels by using the

CHANNEL key on the remote, you must first create the channels. See

Creating a New Channel on page 3-11.

Creating a New Channel

To use a new source with the projector, a new channel must be created so that the projector will respond to an
Input signal from that source. A new channel can be created automatically, or it can be copied from an existing
channel and then edited as necessary. See Copying a Channel on page 3-13. When you select a direct input
(

SLOT 1, SLOT 2, SLOT 3, or SLOT 4), the projector searches for any existing channels that match the 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 the currently defined channels, a new channel is temporarily created based on
factory-defined defaults for the new type of signal. The channel number assigned is lowest available number
from 01-99.

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. 2) If 2 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.

3.4.1 Automatic Image Setup

Auto setup is a good first step in setting up the image. Press AUTO on the remote. This optimizes critical
display parameters such as size, position, pixel tracking, etc., based on the type of incoming source. An auto
setup can save considerable setup time, and you can still adjust the image as described below.

The best auto setup will be obtained under the following conditions:

• Input levels: It is best to have an image with saturated (very bright) colors.

• Phase: High contrast edges are needed.

To determine active window size:

• Video images should have whites and blacks in the image

• Wide range video images should have content (including white) that extends to all edges of the image.

3.4.2 Size and Position Menu

Increase or decrease the size of your image, change
its proportion (aspect ratio), move the image to a
specificarea of the screen, and refine other related
parameters. Use Size and Position controls to
match the image precisely to the screen used at the
site. See 3.2.4 Using Slidebars and Other Controls
if you need help using any of the options and
controls. Changes made in the Size and Position
menu are applied immediately and are saved when
you exit the menu (press

EXIT or MENU).

Resize Presets

Resize Presets will display an image in its native
resolution (no resizing) or will resize the image by
maximizing either the height, width or both height
and width, or will resize to the maximum size
possible while keeping the original aspect ratio.
Size, Position and Blanking parameters will
automatically adjust accordingly or, if Blanking is
set first to define an Active Input Area; Resize
Preset scaling will occur in this region of interest only.

• Custom re-size option does not initially appear in the Resize Presets drop down list.The Resize Presets
value changes to Custom automatically when any of the values for Size, Vertical Stretch, H-Position, V-
Position or Blanking do not correspond to those for a preset option.

Section 3: Operation

•Select Default for most sources (factory default). The image will be centered and displayed as large as
possible depending on the type of source.

By default when displaying a new source, your image will use as much of the projector display area as
possible for the type of incoming source data, but with minimal or no changes to aspect ratio.

• No Resizing displays the image in its native resolution, which may or may not match the projector
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 as shown below.

• Full Size uses 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.

• Full Width fills the projector 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”).

• Full Width fills the display from top-to-bottom. Depending on the source, this may create borders.

Section 3: Operation

• Anamorphic displays 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

Controls both the image width and height, maintaining the current aspect ratio of
the displayed signal data.

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 ensures that the image quality is consistent across the screen, the aspect ratio is
maintained, and that the pixel phase can be optimized (described in Pixel Phase on page 3-18). Tracking
determines the frequency of the pixel-sampling 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 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 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 as described in Pixel Phase on page 3-18.

Pixel Phase

Adjust “Pixel Phase” after “Pixel Track”. 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. Adjust the slidebar until the image stabilizes and each pixel is
clearly defined. You may notice that you can stabilize the image at more than one point. For example, you may
find that the image appearance at “11” is identical to the image appearance at “38”, 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

Move the image right or left within the area of available pixels. The value shown represents the approximate
center of the image in relation to the total number of horizontal pixels. It varies widely according to the signal;
watch the image while adjusting.

V-Position

Move the image up or down within the area of available pixels. The value shown represents the approximate
center of the image in relation to the total number of vertical pixels. It varies widely according to the signal;
watch the image while adjusting.

Keep Aspect on Auto Setup

Maintains the input aspect ratio when calculating the default size in auto setup. If disabled the source is scaled
to fit the platform, except where the video source includes a defined default stretch.

a Primary Image

Active Input Window

This read-only value indicates the current size 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. Specify the active input window size by
adjusting one or more Blank settings (Figure 3-10).
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.

Blanking (Top, Bottom, Left, and Right)

Crop the image so that unwanted edges are removed from the display
(changed to black). Blanking defines the size of the Active Input
window, or area of interest. Range of adjustment depends on the source
resolution, and other factors.

NOTE: When certain RGB signals are first connected, the projector may not recognize them as RGB and will
incorrectly decode their color information as YCbCr (video). These signals can include:

• RGB signals in NTSC, PAL, SECAM frequency ranges.

• Scan-doubled sync-on-green.

NOTE: Generally, use “Auto” for all instances except: a poor quality input signal or 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. 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

Adjusts the red/green color hue for true color reproduction of video and HDTV signals. For best results,
adjust tint while displaying an external test pattern. It is recommended that tint remain at its default setting.

Section 3: Operation

•Filter

The proper filter setting is automatically set for virtually all signals, and rarely needs to be changed. 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.

• Sampling Mode

Sets the color sampling mode for a digital signal to either YCbCr 4:4:4, RGB or YCbCr 4:2:2. The proper
sampling mode is determined automatically by the projector; you can override this setting.

• Film Mode Detect

Enable or disable film motion detection. Only available for interlaced or segmented frame sources.

• Chroma/Luma Delay

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.

• Adaptive Contrast

Dynamically expands the contrast of the output image producing vibrant images with seamless response to
scene changes and fades. The slide bar adjusts the amount of adaptive contrast to apply, with a setting of “0”
producing no change.

• Split Screen

This control allows a snap shot of the main image to be presented on the right side or lower part of the screen,
to allow evaluation of advanced image processing features. All resizing controls are honoured on both images.
However, image processing controls (such as, Detail, Sharpness, Noise Reduction and Adaptive Contrast) only
happen on the left side or top image. Changing inputs, channels or test patterns will disable this control.

• RGB Quantization Range

This control defines the RGB quantization levels for digital DVI and HDMI inputs using the RGB color space.
Typically, graphics sources use the full range of levels for the given bit depth (i.e. 8-bit, 10-bit, 12-bit) and
consumer electronics (CE) products typically use a limited range of data within the given bit depth. This
control must be set to Limited to correct the levels for those CE products that use the limited space. This adjusts
what is considered black and white levels in the image. As an example for 8 bit space, full range RGB uses
levels 0 (black) to 255 (white). A limited CE range is 16-235 for 8-bit video sources.

Input Levels Menu

Only experienced users should use the Input
Levels submenu. The projector automatically

optimizes input levels for all but the most unusual
of sources. Before starting, check that overall
contrast and brightness settings are near 50 and
that color temperature is properly set up on an
internal grayscale test pattern. Good RGB or input
levels (that is, the drives and black levels for each
of the 3 colors, red, green and blue) ensure that
images from analog sources other than decoded

Section 3: Operation

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.

For a source exhibiting overly high black levels (typically caused by a noisy source causing black level spikes)
use the Input Levels menu (3.3.1 Inputs, on page 3-10). These adjustments, serve as a calibration process
compensating for differences in sources and cabling, to perfect the source image input levels and eliminate
“overshoot” and “undershoot”.

NOTES: 1) Input Levels are of limited use with digital signals, but do offer some ability to tweak poorly­mastered source materials. 2) Input levels apply for the current source only, but for any color temperature
used. 3) 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

Use 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 check
mark, wait for the 6 slide bar values to stabilize, then delete the check mark, and exit. The Auto Input Level is
automatically turned OFF upon exit from the Input Levels menu.

• Black Levels and Drives

NOTICE: Do not use Input Levels to adjust color temperature. This will distort contrast and brightness

functions, as well as color temperature.

To check your image levels and adjust these controls:

1. Confirm that you are using an input on a Dual Link DVI card. Input Levels are not applicable for sources
going through the decoder.

2. Display a representative image for source you are setting up.

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

4. If black levels are too high (or whites are too low, which is rare), you likely have a noisy source that is
producing skewed input levels.

5. To adjust levels automatically, check to enable Auto Input Levels in the Input Levels menu. Wait for all
six Blacklevel and Input Drive values to stabilize. Uncheck the Auto Input Levels option.

NOTE: Do not use Auto Input Levels for dark images.

6. Exit the Input Levels menu. Exiting the Input Levels menu automatically disables Auto Input Levels and
Auto Color Enable.

• Auto Color Enable

When a check mark is present, select a specific black level or drive will automatically enable the
corresponding color in the display. Delete the check mark to see all colors, or to enable a different specific
color through the Color Enable control.

Clamp Location brightens the image produced from certain high-resolution high-frequency graphic sources.
The projector automatically selects the best clamp location for most 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

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

2. Display one primary color.

NOTE: Select Auto Color Enable to ensure that the correct color is displayed for each setting.

3. For the current color, adjust its corresponding Black level slidebar just until a single band of black appears
at one edge of the screen. This band represents the first band of the grayscale pattern. It should be 100%
black.

4. With the same color still active, adjust its corresponding Input Drive slidebar 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).

5. Check the black band and adjust the black level slidebar, if necessary.

NOTE: Adjusting the black levels affects the gain. Only adjust when necessary.

projector.

Gamma Settings

The system offers 2 types of gamma correction.
Gamma correction can be applied to a specific source
to correct for luma encoding. This is a channel setting
and reapplied every time the same signal is detected.
This is the 'Gamma' control. On the other hand the
system also provides a global Gamma Correction
control. The global control offers an offset applied to
all channels. This offset is used to compensate for
changes in ambient conditions, such as ambient light in
the room and projected material.

Mirage WU-L User Manual 3-25

020-100774-01 Rev. 2 (4-2012)

Section 3: Operation

Figure 3-12 Gamma Curve

•Gamma Correction

Applies a global offset to all gamma settings for each channel. It affects the shape of the curve by performing
a linear transform toward a gamma curve of 1.0 while the control is increasing and likewise a linear
transform toward a gamma of 3.0 as the control is decreasing. The control should only be adjusted to
compensate for ambient conditions. To correct a particular source only, use the Gamma control.

•Gamma

Select the base gamma table for a given source. Select from one
of the standard tables, a custom gamma function, or select an
arbitrary gamma table that has been downloaded to the projector.

NOTE: A separate PC utility is needed to do this.

The 2.22 curve is a power curve typically used to encode graphics
and video sources, see Figure 3-12. The 'standard' curve (auto
setup default) is a modified 2.22 curve with a small linear section
in the black that enhances the detail in darker areas of the projected content. Typically standard or 2.22 is
used for all sources. Alternatively, if neither default is ideal, apply a simple gamma curve by defining a
custom power function and slope. Select Gamma Function to enable the function and slope controls. For
more complex non-standard gamma curves, a user-defined curve created externally and downloaded to the
projector can be used (requires separate PC-based Arbitrary Gamma software application to create the table,
and the Web UI to download it).

NOTE: If any of these special user curves have been installed, their names will appear in the Gamma Table
drop-down list.

• Gamma Function

Defines the base gamma power curve used when the base Gamma table value is set to “Gamma Function”.
This value, combined with the Gamma Slope setting determines the base Gamma table to be used as the
custom base table. The curve is generally a power curve with a small linear segment at the bottom defined by
the slope.

•Gamma Slope

This control defines a slope to be used for the base custom Gamma table for a small section at the bottom of
the curve. This slope can be used to bring in or out the low level blacks in the image. This slope, combined
with the gamma function, defines the custom Gamma table.

Detail Settings

Adjusts the sharpness of the image. Setting detail
above the halfway point can introduce ‘noise’ in the
image. Lower settings can improve a noisy signal.

•Detail

Adjust the sharpness of the image. Setting detail

Discrete Cosine Transform (DCT) based
compression processing.

• Mosquito Noise Reduction

Reduces mosquito artifacts around sharp edges in DCT based compression by dynamically adapting to
image content.

• Split Screen

Allows a snap shot of the main image to be presented on the right side of the screen to allow evaluation of
advanced image processing features. All resizing controls are honoured on both images; however, image
processing controls only happen on the left side image. Changing inputs, channels or test patterns will
disable this control.

• Full Screen Eye-Motion Filter

Check this control to apply the eye-motion filter to the entire screen rather than applying just to the edge
blending regions.

• Eye-Motion filter

Adjust this filter to reduce the saccadic eye-motion sometimes noticeable in edge blending regions. Too
much filtering may result in loss of detail. For best results, adjust this setting while positioned at the nominal
screen-viewing distance.

Frame Locking

Select how the projector controls the output frame timing based
on the input signal. When set to Frame Lock, output image
frames are locked to the input if possible. When locked, the
output is always locked to the primary input. When set to Free Run, sets the output to the Free Run
Frequency value. The projector will not display 3D content when set to Free Run.

Section 3: Operation

NOTE: Frame locking on projectors in a ArrayLOC

network can be controlled from one projector. See

Synchronize Frame Delay on page 3-54. When

Synchronize Frame Delay is used, the master
projector sets the frame delay for the synched
projectors in the array.

Set Frame Delay

This control delays the output signal timing relative
to the input signal timing by a fraction of a frame,
and up to several frames. The minimum latency can
vary based on the amount of scaling applied to the
image. When using keystone or warping, an
additional latency is required, depending on the
amount of warp. The control is only available when
the input signal is frame locked.

In Free Run mode, or in cases where the signal cannot be frame locked, the minimum latency defined by the
scaling and keystone/warp is applied to the signal.

NOTE: Frame locking on projectors in a ArrayLOC network can be controlled from one projector. See

Synchronize Frame Delay on page 3-54. When Synchronize Frame Delay is used, the master projector sets the

frame delay for the synched projectors in the array.

Brightness Uniformity

Brightness Uniformity provides further
refinement of displays already matched for
their primary colors and overall light output.
Use the Brightness Uniformity menu
options for basic adjustments so that no area
appears brighter than another. In the

Brightness Uniformity menu, enable the
Brightness Uniformity Enable check box to

access a multitude of adjustments for light
output control in specific areas throughout
the image. Your settings apply as long as the
Brightness Uniformity Enable check box is
enabled.

While making adjustments, enable the

Coarse Adjustment check box to apply
Brightness Uniformity settings with a large

granularity. Coarse Adjustment helps
identify brightness changes and accelerates
projector response time while adjusting
settings. To disable the Brightness

Uniformity function, delete the Brightness
Uniformity Enable check mark.

To correct brightness uniformity for a
complex screen setup, see the TWIST User Manual (020-100143-xx).

When used to refine screens already matched for their primary colors and overall light output, proper
adjustment of Brightness Uniformity can create an exceptionally smooth screen in which:

• No area of the screen appears brighter than another

• 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.

Edge Blending

The Edge Blending submenu provides a range of basic controls for smoothing together the overlapping bright
edges of multiple adjacent projected images to create a single larger “seamless” image. These controls, which
primarily affect white levels, are typically used in conjunction with mechanical lens blinders (optional), which
are installed on the front of the projector and which primarily affect black levels. Brightness uniformity
adjustment, if desired, should be performed first. The Edge Blend or Grid test pattern is useful for the
mechanical setup of the projectors. If necessary, adjust Black Level Blending first with the Black test pattern,
then use the White test pattern to blend the white levels on the blend edges. The final step is to check the
blended image with an external source.There is a centerline (both horizontal and vertical) in the Edge Blending
test pattern. The intersection of these lines is the true center of the projector display area.

Figure 3-18 Edge Blending Concept

The Show Blending Overlap control enables or disables edge blending
overlap. When enabled, this will make the size of the Edge Blending regions
obvious. This control should only be used during setup.

For information about advanced blending of complex configurations, for
example with spherical screens, see the TWIST User Manual (020-100143-xx).

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 (Figure 3-17).

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 disappear
(Figure 3-18). 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, so
projectors must be located very close to one another.

Edge blending software controls are located in the Edge Blending submenu, which can be accessed using
Configuration > Geometry & Color > Edge Blending. The Advanced Edge Blending option opens to the
second page of the Edge Blending submenu.

overlapping edges together smoothly.

NOTE: For information about advanced blending
of complex configurations, for example with
spherical screens, see the TWIST User Manual
(020-100143-xx).

Blend Width

Determines how much area is used for blending
along an overlapping edge. Slide bar values
represent the number of pixels used for the
blend. For example:

• A setting of 8 creates a blended edge 8
pixels wide.

• A setting of “0” signifies no blending.

For best results in most applications, use a blend width of 12-25% (for example with a screen size of
1920 × 1200, 230-480 pixels). NOTE: Ranges: 0-960 horizontal, 0-600 vertical.

Mirage WU-L User Manual 3-39

020-100774-01 Rev. 2 (4-2012)

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 2 adjacent images. Clear the Show Blending Overlap check box to reactivate the blend
effect.

Other Functions

For convenience, the Edge Blending submenu also includes related options for enabling a test pattern. Such
functions duplicate those provided elsewhere in the menu system.

Advanced Edge Blending Controls

Use advanced edge blending controls to
more finely control the blend curve.

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 mid-gray. 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.

Edge Blending Procedure

NOTES: 1) Before attempting to work with edge blending software functions, align the projectors/images by

correctly overlapping the displays from your intended external source. 2) Match colors and the brightness
uniformity.

NOTICE: 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 selecting Standard for non-warped images.

3. Set Starting Points For Adjustment.

a. Set all blend widths to 0.

b. Go to Advanced Edge Blending and set all options to 50.

4. Set Blend Width

. On one projector, increase the Blend Width for an overlapping edge (for example, if the

projector image is on left, its right edge overlaps the adjacent image by adjusting Right Blend Width).
Use the same setting on the second projector for this shared edge.

3-40 Mirage WU-L User Manual

020-100774-01 Rev. 2 (4-2012)

Section 3: Operation

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.

NOTE: If the best blend appears to be between 2 settings, choose the wider setting for both projectors.

6. Check the blend and adjust as required:

• To lighten the overall blend, increase the Blend Midpoint in both projectors.

• To darken the overall blend, decrease the Blend Midpoint in both projectors.

• To fine-tune the amount of mid-gray intensity (as opposed to black/white) in the blend, adjust Blend

Shape in both projectors.

7. Repeat with remaining projectors/overlaps.

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

9. If necessary, adjust the mechanical alignment to maintain perfect pixel-on-pixel alignment over time.

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.

NOTE: Recommended overlap is 12.5%–25%.

Black Level Blending

Brightens the center regions to match
adjacent blend regions when edge blending
multiple projectors. The Black Level
Blending submenu provides controls that
allow you to adjust the black level hues of
multiple adjacent projected images to create
one large seamless display.

NOTES: 1) Adjust edge blending before
adjusting black levels. 2) Blinders are
recommended for fixed installations. 3) Do
not use black level blending if TWIST was
used for the geometry.

Black Level Blending Procedure

NOTES: 1) Adjust edge blending before

adjusting black levels. 2) The zones in Black
Level Blending 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.

Mirage WU-L User Manual 3-41

020-100774-01 Rev. 2 (4-2012)

Section 3: Operation

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

2. In the Black Level Blending submenu, enable black blending.

3. Set the blend width.

4. Working with one projector at a time, use the center brightness slidebar to adjust the center brightnesss
(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 2 x 2 display is the target area).

5. You can choose which of the next 4 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.

6. The brightness and black hues of the blended region can be adjusted in more detail in case fine-tuning is
needed (may be necessary only for blending a 2 x 2 projector display because of blending differences 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 brightnesses following the overlap adjustments on each blended edge. 3) When adjusting 6 or
more projectors, you need to ensure that the hue and brightness of each target area is matched at closely as
possible.

Manual RGB Adjustment

These adjustments can turn on
multiple RGB LEDs simultaneously, which uses
more power and increases the possibility of
overheating.

The Manual RGB Adjustment menu lets you
manually adjust the native projector color space by
adjusting the LED power levels. The brightness of
unsaturated colors can be significantly increased by
turning on multiple RGB LEDs simultaneously.

Interaction with ColorLOC

When Bright/ColorLOC is OFF or in Fixed mode,
these adjustments can be used to define the color
gamut. In Cool or Bright mode, the projector
automatically moderates the LED power level to
maintain the color gamut selected through the Array
Color Target menu. See How Color Settings Interact

in a Mirage WU-L Array on page 3-61.

Section 3: Operation

Input Peak Detector

This is a fast method for defining individual input levels, and improving 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 2 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 display correct blacks and whites without crushing or washing out.

Input Level Detector

The Input Level Detector check box 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. To use:

1. Enable Input Level Detector and display a continuous grayscale.

2. Set Level Detector Threshold to near black (such as 200).

3. Adjust Offsets to minimize area of black stripe.

4. Set Level Detector Threshold to near white (such as 800).

5. Adjust Gains to minimize area of white stripe.

Level Detector Threshold

Input Level Value defines the value to be used by the Input Level Detector in recognizing blacks and whites.
See Input Level Detector, above.

Aspect Ratio Overlay

Check this box to display an overlay pattern over the image. The overlay shows the boxes corresponding to the
size and shape of different aspect ratios.

Tes t P attern Color Swap

This function swaps the green and red color when drawing the Grid test pattern, and may be helpful when
adjusting convergence on the projector.

Freeze Image During Auto Setup

If selected, this will hide temporary image artifacts that may appear during the auto setup procedure.

Advanced Diagnostics

Allows for the setting of advanced controls which
may cause image disruption, including the possible
loss of the OSD menus. These disruptions are only
temporary; pressing

EXIT to exit the menu will restore

the settings and allow normal operation.

Output Peak Detector

This is an aid for setting up the input levels. It
causes the data to be processed so that very bright and very dark signals display as fully ON or OFF, and
everything in-between is set to mid-level gray. The Input levels should be adjusted so that bright and dark
objects in the image are just visible.

Output Level Detector

This is an aid for setting up the Input levels. It causes the data to be processed so that all levels below a
specified value are set to black and all above (and including) it are set to white.

• Minimum brightness not met (BCLOC disabled)

• Minimum brightness not met (Warning)

• Min Gamut not met (BCLOC disabled)

• Min Gamut not met (Warning)

Bright/ColorLOC Mode

Use this option to set the Bright/ColorLOC mode.

•In ALL modes (except OFF), the projector:

• Sets the flag to execute the Array BCLOC algorithm.

•In Cool or Bright mode, the LM color adjustment options on the Manual RGB Adjustment menu are
disabled.

Mirage WU-L User Manual 3-45

020-100774-01 Rev. 2 (4-2012)

Section 3: Operation

• Cool mode: LED control performed by BCLOC. Color Space Correction is also performed
electronically to achieve the target color space.

• Bright mode: This is the recommended (default) mode. The Bright mode is the same as Cool, except
multiple LEDs may operate at the same time. This mode should provide brighter performance, but it will
also generate more heat in the system.

•In OFF mode, the projector:

• Disables BCLOC. Color control is done manually through Manual RGB Adjustment and manual color
settings.

• Clears the flag to execute the Array BCLOC algorithm.

• Restores the LM color adjustment options on the Manual RGB Adjustment menu and the manual color
adjustments.

• Ignores setting changes sent by a projector with the master flag set (Synchronize to this Projector on

page 3-46).

•In Fixed mode, the LED setting is derived from Manual RGB Adjustment; Color Space correction is
performed electronically to achieve the Target Color Space.

Synchronize to this Projector

To broadcast the ArrayLOC settings to the projectors in your array, you must define a projector as the
“master” by checking the option Main Menu > Configuration > ArrayLOC > Synchronize to This
Projector.

The master projector has access to most settings under the Bright/ColorLOC Configuration and Array
Color Target submenus. These settings are greyed out on the other projectors in the array to prevent
conflicting information from being sent to the array.

You can change which projector is the master at any time, by checking the Synchronize to This Projector
option on another projector. The previous master projector automatically releases the setting.

See ArrayLOC Status on page 3-52. See Bright/ColorLOC Configuration > Bright/ColorLOC Array
Status to check projector information.

A projector with BrightColorLOC mode turned OFF ignores BCLOC changes from master projectors.

If at some point you are working with another projector within your array or group, and decide to make some
setting changes, you may not be able to do so as some settings will be locked (grayed out) because their
projectors may not be the current master. You can however select the new projector as the master (as described
above), and make your required changes. The previous master projector will relinquish control.

Minimum Brightness

Use this option to set the minimum
brightness (as a percentage of the target
brightness) that the array will target, and to
set the threshold for alerts from projectors
that cannot achieve the minimum. Projectors
that fall below the minimum are excluded
from the calculations of the common gamut
and common brightness. Excluded projectors
are flagged in the Bright/ColorLOC Array
Status window with an M.

If the projector falls below the minimum, the
projector operates at its current brightness
and gamut. Changes will not be made.

Minimum Gamut

Section 3: Operation

Use this option to set the minimum gamut (as a percentage of the target gamut) that the array will display,
and to set the threshold for alerts from projectors that cannot achieve the specified minimum. Projectors that
fall below the minimum are excluded from the calculations of the common gamut and common brightness.
Excluded projectors are flagged in the capabilities window with a m.

If the projector is unable to maintain the minimum gamut, the projector operates at the current brightness and
color gamut. LED drive level changes and electronic color correction is not done.

NOTE: The failure point for maintaining minimum gamut is
calculated as:

For example, see the diagram at the right. Where b is the length
of the line from the target white point to the target color primary,
and a is the length of the line from the target white point to the
intersection of the projector capability gamut line and the line
from the target white point to the target color primary.

Projector Capability

Identifies the projector capability with respect to the array­common color gamut as defined by Color Target and Brightness
Target. 100% indicates the projector meets the target. A greater
number indicates that the projector can exceed the target. A smaller number indicates how much the
projector falls short of meeting the target.

Use the Synchronized option to set the projector to listen for remote keystrokes through the ArrayLOC
network and the master projector. All synchronized projectors respond to the same keystrokes. Double key
strokes may not register correctly, use alternate key commands instead.

A synchronized projector automatically starts listening to its IR receiver if the master projector becomes
unavailable, for example if it goes into standby mode.

You can override the key synchronization by using the Proj key and projector address to communicate with
a specific projector, or you can use a wired remote with a specific projector.

Independent indicates that the projector listens to its own IR remote receiver. It is the default option.
Change this setting for each projector individually.

NOTE: ArrayLOC network communication overrides RS-232 serial communication for keys.

Synchronize Frame Delay

Use the Synchronized option to synch the frame delay on all the synched projectors in the ArrayLOC
group. Set the delay value in Set Array Frame Delay.

NOTE: To use this synchronization feature, set

FrameLocking to FrameLOCK. See Frame Locking on page 3-29.

Independent is the default option. Change this setting for each projector individually.

Set Array Frame Delay

This option indicates the current frame delay for all the synched projectors in the ArrayLOC group. Use
this control on the master projector to adjust the frame delay for the synched projectors in the ArrayLOC
group. Set the value equal to or higher than the reported Minimum Array Frame Delay value. Setting the
value lower than the reported minimum may result in tearing artifacts.

Section 3: Operation

Minimum Array Frame Delay

Indicates the largest minimum frame delay reported for the ArrayLOC group. The value is the largest of
the reported minimum frame delay required to render the display without tearing artifacts on each
projector in the ArrayLOC group.

Synchronize RGB Brightness

Use the Synchronized option to synch the RGB brightness for all the synched projectors in the ArrayLOC
group.

Change this setting for each projector individually. Synchronized is the default option.

RGB Brightness Target

Use this option to adjust the target brightness for all projectors in this array.

RGB Brightness

Use this option to adjust the brightness of the projector array as a percentage of the target brightness.

Managing Colors with ArrayLOC

Mirage WU-L projectors use ArrayLOC to display a reasonably saturated gamut at the maximum brightness
that all the projectors in the array can support. ArrayLOC monitors the projector array and adjusts settings
automatically.

To manage color using ArrayLOC:

• Take Control of the Array on page 3-55

• Adjust Projected White and Primary Colors for the Array on page 3-56

• Fine-tune Whites, White Brightness, or Primary Colors on page 3-57

• Fine-tune Projector Colors With a Color Meter on page 3-58

NOTE: ArrayLOC is enabled by default.

Take Control of the Array

To make color adjustments across the array, you must
make the projector you are working with the master
projector.

1. On the projector you want to work with, access
the ArrayLOC menu: Main Menu >

Configuration > ArrayLOC.

2. Check Synchronize to This Projector.

The current projector becomes the master
projector. Changes you make in the Array Color
Target or ArrayLOC Configuration menus on
the master projector are broadcast to the other
projectors in the array.

020-100774-01 Rev. 2 (4-2012)

Section 3: Operation

Adjust Projected White and Primary Colors for the Array

User-defined target color spaces allow color primaries and white points to be adjusted independently. For
example, you can select the target color space User 1, copy the values from the target color space Factory,
leave the color primaries, and adjust only the white point. All the settings for a user-defined color space are
editable.

1. Navigate to Main Menu > Configuration > ArrayLOC > Array Color Target.

2. In Target Color Space, select one of the User settings to modify.

NOTE: To use another color space as a starting point, select a source color space from the Copy Color

Space From list. When using Maximum as a starting point, the values reflect a color space larger than
capable for the best array color saturation. The values may not reflect real-world colors.

3. Check both Auto Color Enable and Test Pattern Enable, the system (background) color changes to the
target color being adjusted (for example, Target Red x invokes a red background). All other menu options
change the system color to white as long as Test Pattern Enable is checked.

4. Adjust the color primaries (for example, Target Red x and Target Red y) for the color space.

5. To adjust white in the image, select a User White item (1 to 4).

• Adjust Target White x and Target White y values, or

• Check the Set White to Color Temperature box and set the White Color Temperature value to any

value between 3200 and 9300°K.

6. To adjust the target brightness for the array, adjust RGB Brightness Target on the master projector. For
maximum brightness, set the value to a large number, such as 1000.

7. If the array appears matched across all projectors for color and brightness, color setup is complete,
otherwise see Fine-tune Whites, White Brightness, or Primary Colors on page 3-57.

NOTE: Array Capability expresses the common gamut red, green, blue and white values of the current

projector as a percentage of the array target color and brightness values (see Minimum Gamut, on page 3-

47). If any of these values is less than 100, there is at least one projector in the array that cannot achieve
target values. Reducing Target Color Space and RGB Brightness Target values in the master projector will
bring the Array Capability values closer to 100.

Fine-tune Whites, White Brightness, or Primary
Colors

Projector Color Adjustment lets you fine-tune color
or brightness for individual projectors that don’t quite
match the array. For more information, see Projector

Color Adjustment, on page 3-41.

These steps outline color adjustments using projector
color settings until the colors appear to match the rest of
the projectors in the array. Color adjustments are
evaluated by eye. A color meter can help determine the
change required, but the results are still evaluated by
eye. For information about using the color meter with
this procedure, see Fine-tune Projector Colors With a

Color Meter on page 3-58.

1. Navigate to Main Menu > Configuration >
ArrayLOC > Projector Color Adjustment.

2. Projector Color Adjustment settings are specific to
each color space. To use existing fine-tuning
adjustments as a starting point, select a tuned color
space from Copy Adjustments From.

Section 3: Operation

3. Check both Auto Color Enable and Test Pattern
Enable, the system (background) color changes to the target color being adjusted (for example, Target Red

x invokes a red background). All other menu options change the system color to white as long as Test
Pattern Enable is checked.

4. Navigate to Main Menu > Configuration > Communication. Note the IDs of the projectors you want to
fine-tune.

5. To adjust white color and brightness settings (repeat for each projector that needs adjustment):

a. Press P

ROJ, <PROJECTOR ID > on the remote. The remote directs commands to the specified projector

only.

b. Use the White Brightness Adjustment to roughly match the white brightness of the array. A higher

value makes the projector image brighter.

c. Adjust the Red Part of White, Green Part of White, and Blue Part of White to match the white

color to other projectors in the array.

d. Readjust the White Brightness Adjustment control if matching white colors revealed mismatched

white brightness.

6. Navigate to Main Menu > Configuration > Communication. Note the IDs of the projectors you want to
fine-tune.

a. Press P

ROJ, <PROJECTOR ID > on the remote. The remote directs commands to the specified projector.

b. Adjust the XXX Part of YYY controls where and YYY is the color being adjusted, and XXX and

YYY are not the same color (ie. non-dominant colors). Negative values for the non-dominant colors
are permitted. Adjusting XXX Part of XXX adjusts the color’s brightness and affects the color of
white.
Example: If the blue primary color does not match. Use the Red Part of Blue and Green Part of Blue
controls. Negative values will increase the saturation of the blue. Values between -15 and +3 work
well.

NOTE: For information about using a color meter with this procedure, see Fine-tune Projector Colors

With a Color Meter on page 3-58.

8. Repeat steps 6 and 7 until all the primary colors are matched.

9. After adjusting the primary colors, verify that the white color and brightness still match. Repeat the process
if necessary.

Fine-tune Projector Colors With a Color Meter

To use a color meter for projector color adjustments, follow the instructions in Fine-tune Whites, White

Brightness, or Primary Colors on page 3-57, but use a color meter for the XXX Part of YYY adjustments.

1. To note the xy color values reported for the common gamut, navigate to Main Menu > Configuration >
ArrayLOC > ArrayLOC Status. For example, see Figure 3-19.

2. Measure the projected primary color with the meter and compare the metered values to the common gamut
values.

3. Use the adjustment guide to determine how to adjust the Projector Color Adjustment values to correct the
differences.

The adjustment guides are color coded. The suggested corrections are also color coded, and

reflect the direction of the change, + or -. For example, if the measured red is 660, 325 and the Common
Gamut value is 640, 330 then the measured x is high (High X) while the measured y is low (Low Y). The
corresponding quadrant of the RED guide indicates +G (increase green) to correct the mismatch with other
projectors.

1

Some corrections require both red and green adjustments.

2

Alternative: decrease blue (-B) instead of increasing red and green.

3

Alternative: increase blue (+B) and increase green (+G) instead of decreasing red, and increasing green.

3.5 How Color Settings Interact in a Mirage WU-L Array

Image Settings > Color Space tells the projector how to interpret video data coming in. See Color Space on

page 3-20.

Image Settings > Advanced Image Settings > Color Settings adjusts the color temperature. Use ArrayLOC
color and color temperature settings instead. When enabled, ArrayLOC overrides the settings on the Color
Settings menu. See Color Settings on page 3-27.

Configuration > Geometry & Color > Manual RGB Adjustment is the manual way to set the levels of each
LED. These adjustments are available when ArrayLOC is OFF or set to Fixed mode. When ArrayLOC is set to
Cool or Bright mode, LED levels are controlled by ArrayLOC function automatically.

Configuration > ArrayLOC > Array Color Target tells the projector what you expect to see on the screen.
This is the recommended way to control the color space for the projector and array. See Array Color Target on

page 3-41. This menu is also available under Configuration > Geometry & Color.

Configuration > ArrayLOC > Projector Color Adjustment lets you adjust each projector output so that it
represents the color target. Adjustments compensate for projector-to-projector differences and for the
projection system as a whole, including loss of brightness or color shift due to lens, mirror, and screen. For
example the mirror might not reflect blue 100 percent, or the screen might absorb more blue. You can measure
the output at the screen with a color meter and use this option to increase the blue until you get the array color
target value at the screen. See Projector Color Adjustment on page 3-50. This menu is also available under
Configuration > Geometry & Color.

Configuration > ArrayLOC > Projector Color Adjustment > White Brightness Adjustment lets you turn
the brightness target adjustment into a meaningful number, for example a number that relates to Ft-L. See

6.6.10 Array Status Decoder & Setting the RGB Brightness Target Unit in the troubleshooting section.

Section 3: Operation

3.6 3D

The Mirage WU-L projector is capable of displaying stereoscopic 3D video sources. The Mirage WU-L relies
on additional hardware, such as stereo emitters and glasses, to complete the display system.

Images generated from a stereo 3D-video source consist of a series of images (frames) that alternate quickly
between two slightly different view points, corresponding to our left and right eyes. When these frames are
displayed fast enough and viewed with special stereo glasses synchronized to the left/right (L/R) changes, the
resulting image appears with the same depth and perspective that is sensed in the real world.

NOTE: The type of special glasses can be active stereo or passive stereo glasses depending on the type of
stereo controllers and screen used.

3.6.1 Requirements

Stereo 3D applications require a stereo 3D-capable source, special hardware/software setups described below,
and the projector’s 3D Settings menu option to control the projector’s processing, synchronizing and
displaying of your stereoscopic 3D source material.

Hardware

• Christie Mirage WU-L projector.

• Christie GPIO 3D Stereo Sync Cable (required for Mirage UI-L projectors; ensures minimum frame delay).

This GPIO cable is standard with all Mirage WU-L projectors.

Mirage WU-L User Manual 3-61

020-100774-01 Rev. 2 (4-2012)

Section 3: Operation

• A source, usually a computer with a stereo 3D graphics card capable of displaying progressive scan

(alternating frames) of OpenGL quad buffered stereo 3D applications. Suggested video cards include ATI or
NVIDIA.

• Emitter for controlling active shutter glasses.

• An appropriate qualified device that mounts in front of the lens of the projector that will process the light

from the lens into a passive polarized light. Contact your Immersive dealer for more information.

Software or content

• Any 3D computer software that supports active or sequential 3D stereo on a supported computer/graphic

card.

• A video stream from video source that has been prepared to be sequential content. The Mirage WU-L also

supports stereo signals prepared on either a compatible Dual or Single link HDSDI format.

port does not support 3D.

• Frame locked Passive sources are also compatible with the Mirage WU-L with the appropriate primary and

secondary input card.

3.6.2 Connecting the GPIO 3D Stereo sync cable

This GPIO cable provides the means for synchronizing the various components in your 3D system. Your
source, projector display output, and emitters or 3D passive filter system can then operate together with
precision to minimize cross-talk and color artifacts. Connect as shown below in Figure 3-23.

NOTE: For Mirage WU-L, inputs A and B are not required, but recommended to ensure that stereo is
configured correctly, especially for multiple projector setups.

NOTE: The VGA

Figure 3-23 Mirage GPIO 3D Stereo Sync Cable

Connecting Two Stereo 3D Sync Inputs (Recommended for multiple sources)

Connect your video card’s stereo 3D sync cable to either Input A or either Input B on the GPIO 3D Stereo Sync
Cable. These inputs are provided to allow you to connect two different Stereo 3D sources and conveniently
switch the display back-and-forth between them.
