VistaGRAPHX 5000 accepts data/graphics and video input signals for projection

onto flat or curved front or rear projection screens. High brightness light is generated by an internal 1000 watt CERMAX modulated by three DMD (digital micromirror device) panels which each provide digitized red, green, or blue color information. Light from the "ON" pixels of each panel is reflected, converged and then projected to the screen through a single front lens, where the pixels are all superimposed to create a sharp full-color image.

The projector body is comprised of aluminum panels with an ABS front bezel.

Covers can be removed as necessary for quick replacement of the lamp or filter.

users or installers should always consult their dealer when deciding on screen type. The following guidelines explain the differences between screen types.

There are two basic screen types: flat and curved. The choice between a flat screen or a curved screen is dependent on audience viewing angle and screen gain. There is always a trade-off between viewing angle and gain. Viewing angles for both screen types are illustrated in Figure 2-1 and Figure 2-2 (plan views).

Flat screens offer a gain of about 1 with a viewing angle just less than 180°. Incident light reflects equally in all directions so the audience can see the display from various angles. Because of the lower gain, flat screens are more effective when ambient lighting is reduced.

)LJXUH 5041 $XGLHQFH &RYHUDJH ZLWK )ODW 6FUHHQ

)LJXUH 5051 $XGLHQFH &RYHUDJH ZLWK &XUYHG 6FUHHQ

Curved screens have gains larger than 1 (due in part to the screen material) and viewing angles much less than 180°. Most curved screens have different horizontal and vertical viewing angles. Incident light does not reflect equally in all directions. The reflected light concentrates in a conical volume or "viewing cone". Audiences within the viewing cone see a brighter image than that from an equal area on a flat screen. Audiences outside the viewing cone see a dimmer image.

NOTE: VistaGRAPHX 5000 lenses are designed primarily for use with flat screens. However, its depth-of-field range allows the lens to be focused on curved screens as well. Focus remains sharp in the corners, however there may be significant pincushion distortion, primarily at the top of the screen.

5HDU 6FUHHQ ,QVWDOODWLRQV

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. 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.

To summarize, optical screens are better suited for brightly lit rooms where the audience is situated within the viewing cone. Diffused screens are best suited when a wide viewing angle is required but there is low ambient room lighting.

Screen size may be from 5 to 40 feet diagonal, depending on the lens you are

using. For instance, a 1:1 lens produces a 6-30 foot image size, whereas a 4-7:1 zoom lens produces a 10-40 foot image 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 eye-to-text distance is less than 150 times the height of the letter. Small text located too far from the eye may be illegible at a distance despite the image being projected sharply and clearly on the screen.

5RRP /LJKWLQ

To fill a screen with an image, the aspect ratio of the screen should be equal to the aspect ratio of the image. The aspect ratio of an image is 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 13.3 feet (4m).

Note: Screen size is often specified as diagonal size. Screens specified by diagonal size have aspect ratios of 4:3. Screens with other aspect ratios are not typically specified by diagonal size.

The high brightness output of VistaGRAPHX 5000 is well suited for locations

where ambient lighting is less than optimum for projection; however, it is desirable that the projector be operated in an ideal projection room environment. For temporary installations where the room may not be designed for projection, there are many simple things which can be done to avoid problems caused by unwanted light.

Visiting a movie theater can give you an idea of what makes a good projection environment. Walls, floors and furnishings are dark and matte finished. A projection room should not have white reflective ceilings or non-directional lighting such as fluorescent lights. The white ceiling spreads light, making the room appear brighter. Keep lighting and reflections to a minimum.

507

9LVWD*5$3+; 8333

If it is not possible to eliminate fluorescent lights, consider using parabolic reflectors ("egg crates") to direct light down to the floor. Incandescent spot lighting is a better way to obtain illumination. Light dimmers or rheostats allow you to further control the lighting.

8VHU*V 0DQXDO

,167$//$7,21 ) 6(783

Outside windows are undesirable in any projection room. A small crack between curtains on a sunny day can wash out a projected image. If you do have windows, make sure that window coverings are opaque and overlapping — some window coverings are designed to provide up to 100 percent blockage of outside light. Ideally, the material should have a matte finish.

To minimize the effects caused by unwanted light from door and aisle ways, carefully choose the position of your projector and screen. Figure 2-3 shows an installation where poor screen placement allows too much unwanted light to enter the screen. In Figure 2-4, the screen and the projector are positioned so that unwanted light is minimized.

)LJXUH 5071 %HWWHU 6FUHHQ 3ODFHPHQW

Even with all lighting removed it is still possible that room reflections within the room can degrade the image. Light from the projection screen should be absorbed by the ceilings, walls and floors so that it will not be reflected back to the screen. Again, reflective surfaces should be kept to a minimum.

Here are some other considerations and tips which can help you improve your

installation:

• Ventilation is an important factor when preparing a projection room. The

ambient temperature should be kept constant and below 35°C (95°F). Keep

9LVWD*5$3+; 8333

8VHU*V 0DQXDO

508

,167$//$7,21 ) 6(783

the projector away from heating and/or air conditioning vents. Changes in temperature can 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 are slide projectors, speakers, power amplifiers, elevators, etc.

• For rear screen applications, less space is required if a mirror is used to fold

the optical path.

• Choose the right screen size for the application: ◊ As screen size increases, magnification increases which reduces

brightness. Select a screen size which is appropriate for the venue, but not larger than that required.

◊ Installing a large screen in a small room is similar to watching

television close up; too large a screen can overpower a room. A good rule of thumb is to be no closer than 1.5 times the width of the screen.

◊ Larger screens require greater attention to lighting conditions.

• When laying out the projection room, consider positioning the projector and

screen in a manner which will achieve maximum audience coverage and space efficiency. For example, placing the screen along the larger wall in a rectangular room will reduce audience coverage. Figure 2-5 shows two examples of how audience coverage is maximized.

Installation type, screen type, and lighting all affect where the projector is positioned. In addition, both throw distance (the distance between the projector and screen) and vertical position (the height of the projector in relation to the screen) must be determined for every new installation. Both depend on the screen size and projector lens type you are using. Make sure that the room can accommodate the required position of the projector for the chosen screen size.

Throw distance is the distance between the projector's front feet and the screen.

It is measured perpendicular to the lens surface and screen surface. As you move the projector farther from the screen, the image becomes larger.

Throw distance is roughly equal to the horizontal width of the screen multiplied by the type of lens you are using (for example, if using a 3.9:1 lens, throw

[

distance should be approximately 3.9

the screen width). Once you know your

screen size, you can closely estimate how far away the projector should be, as shown in Table 2-1. Always refer to Appendix E for permanent installations.

NOTES: 1) While throw distance is measured perpendicular to the screen and projector, this measurement is not necessarily parallel to the floor—both projector and screen may be inclined together. 2) It is good practice to simulate the setup with the projector fully warmed-up to determine the actual throw distance required. 3) Always refer to Appendix E for permanent installations.

The vertical position of the projector in relation to the screen also depends on the

size of the screen and the lens type. Correct vertical position helps ensure that the image will be rectangular in shape rather than keystoned (having non-parallel sides) and that image quality remains at its best.

Vertical position can be manually offset—that is, the image can be moved up— using the vertical adjustment knob on the front of the projector. The range of adjustment depends on the lens type you are using (Table 2-2). In addition, refer to Figure 2-6 to see more clearly how the pixel offset ranges affect the placement of your image in relation to the vertical location of the projector.

Note that VistaGRAPHX 5000 can be rotated and mounted at any vertical angle- i.e., you can tilt the projector forwards or backwards as much as desired for your application. The side-to-side tilt, however must not exceed 45° (see Figure 2-7). This limit ensures that the arc lamp in the projector operates properly and safely.

If the projector is to be inverted, a ceiling mount fixture is required. Electrohome provides a ceiling mount kit for assembly and installation by a dealer/installer. For more information, contact your dealer or Electrohome.

In rear screen applications where space behind

the projector is limited, a mirror may be used to fold the optical path. See

Figure 2-8. The position of the projector and mirror must be accurately set. If considering this type of installation, call your dealer for assistance.

The rear panel of the projector has two standard input panels to which you may connect a variety of sources. The upper right panel (INPUT 1) accepts an RGB input from an external RGB source with audio follow-through. The lower left panel (if video decoder module is installed) accepts composite video (INPUT 3) or S-video (INPUT 4) and audio from devices such as video tape or disk players. There are also several optional interfaces available for connecting other sources (INPUT 2). Such an option installs in the upper left panel. See Figure 2-9.

The RGB input (INPUT 1) includes BNC type connectors for connection to a

variety of RGB sources. Such sources include VGA, SVGA, XGA, Mac, PowerMac, DEC, Sun, SGI and others. VistaGRAPHX 5000 supports multiple sync types: sync-on-green for data, composite, and separate H & V.

NOTE: Depending on the source, you may need a custom adapter cable that has BNC connectors at the projector end and different type of connector at the other (such as a 15-pin "D" connector for computer sources). Contact your dealer or Electrohome.

Connect the sync BNC input(s) first. Then connect the red, green and blue source outputs to the RED, GREEN, and BLUE inputs on the panel. If the source uses sync-on-green, only the red, green, and blue connections are required. If the source provides a composite sync output, connect it to the H/C SYNC input. If the source provides separate horizontal and vertical sync outputs, connect horizontal sync to the H/C SYNC input and connect vertical sync to the V SYNC input. See Figure 2-10.

Connect YUV (component) video as follows:

Y to "Green" U (also called B-minus-Y) to "Blue" V (also called R-minus-Y) to "Red"

NOTE: VistaGRAPHX 5000 does not automatically recognize a YUV signal. When using YUV video, you must specify this signal type within the Image Settings menu so that the projector can distinguish between this signal and other RGB sources. See 3.6, Adjusting the Image.

VistaGRAPHX 5000 is set up at the factory for use in a front screen, floor mount orientation. If the installation is ceiling mount or rear screen, you may notice that displayed images are upside down and/or reversed. To correct, you must change the image orientation from within the Preferences menu (you may prefer to do this before physically installing the projector). See Section 3, Operation for further information.

In the Preferences menu, highlight and select the "Image Orientation" pulldown list. From a front screen floor mount installation, select from Rear, Inverted Rear, Front or Inverted Front according to your intended installation:

For most installations, the lens surface of the VistaGRAPHX 5000 projector must be parallel to the screen to prevent keystoning. To make small corrections to the projector's level, rotate each leg as necessary to raise or lower.

Once the VistaGRAPHX 5000 is properly set up and projecting an image on screen, you are ready to make quick manual display adjustments.

If you are using a zoom lens, turn the outer shell of the lens barrel to decrease or

increase the size of the image at the current throw distance. Note: Do not touch the lens surface as it can be easily damaged.

Turn the Focus adjustment knob (next to lens barrel) until you obtain the best

overall image clarity. VistaGRAPHX 5000 includes a Vertical Offset adjustment knob to provide

vertical image shifting (raising and lowering) without causing keystone distortion. Proper adjustment can also maximize display brightness. Turn the knob until you achieve the best overall brightness without causing a distortion in picture geometry.

For further display adjustments through keypad commands and on-screen menus, refer to Section 3, Operation.

Use serial communication ports when controlling VistaGRAPHX 5000 with a personal computer having a serial interface or when using the projector with a Marquee switcher. VistaGRAPHX 5000 serial ports are located on the lower right portion of the projector's rear control panel as shown in Figure 2-14.

You may wish to use a computer rather than a keypad for controlling the projector and for performing other special functions. From most computers, connect an RS-232 serial communication cable between the computer and the projector serial port labeled "NETWORK IN" (Figure 2-15). Then set the projector baud rate to match that of the computer. Changing the baud rate is described in 3.7, Adjusting and Checking System Parameters.

NOTE: In rare instances, some computers can provide RS-422 serial communications (generally through a plug-in adapter or external converter). See The RS-422 Port, below.

In rare instances, some computers can provide RS-422 serial communications (generally through a plug-in adapter or external converter) rather than the typical RS-232 found on most computers. RS-422 communications occur at a higher voltage level than RS-232 and are especially useful for distances greater than 600 feet. The projector’s RS-422 port is permanently set at 9600 baud.

If you wish to control the projector with a computer having RS-422 capability, connect the computer to the projector’s RS-422 port instead of the port labeled “NETWORK IN”. Again, use RS-422 only if you are certain that your computer has RS-422 capability (consult your documentation). See Figure 2-16.

Each projector can be assigned a unique 3-digit projector number (for example,

001). These numbers are particularly useful when you are working with multiple linked projectors, enabling you to direct commands to a certain projector rather than broadcast to all projectors. For complete information on how to assign projector numbers, see 3.7, Adjusting and Checking System Parameters.

3URWRFROV

At manufacture every keypad is assigned a default protocol, which is simply a collection of settings that determine how the keypad operates. Once assigned, this protocol remains in effect until it is changed — that is, the keypad will operate as it currently does until you change its protocol.

Protocols are most useful for multiple-projector applications. For example, you might want to change a keypad protocol if you are working with two projectors and two remote keypads in the same room and need to control each projector independently (Figure 2-20). When Keypad 1 has a different protocol than Keypad 2, each keypad communicates only with the projector having a matching protocol. Or, if you have a network of two or more projectors connected together via RS-232 serial ports, you may want only certain projectors to respond to a wired keypad.

NOTE: Matching the protocol on the projector to that of a keypad is done through a setting in the VistaGRAPHX 5000 Preferences menu. See 3.7, Adjusting and Checking System Parameters for further information on how to change the projector's infrared sensor (rear and front) protocol.

A protocol for either type of remote keypad — IR or wired — can be changed through software commands entered on the keypad. A new protocol set through software commands remains in effect until the keypad batteries are removed and replaced (if an IR remote), or until the keypad is unplugged (if a wired remote). A remote can also be changed manually — you can "hard-wire" new jumper settings inside the keypad so that they remain in effect until you change the hardwiring. Note that a hard-wired protocol can be temporarily overridden by the

A channel is a collection of measurements and settings that tailor a display to your specific needs. Since source types and applications vary greatly, you will likely want to adjust and define a wide variety of parameters, such as brightness, contrast, tint, etc., in order to customize and maximize the display coming from that 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, or one signal may vary from another used earlier through the same input location. Once you have adjusted a display parameter, such as zoom, focus, or pixel tracking, all current settings are collectively stored in the projector's memory as a unique 2-digit channel, such as

NOTE: By default, the projector samples at the correct frequency for a given source. For best results, it is recommended that this default not be overridden.

Pixel tracking is adjusted most effectively using a good test pattern, such as a smooth gray image made up of a clear pattern of tiny black and white dots, or a similar graphic image. Steady flickering or several soft vertical stripes or bands across the entire image indicates poor pixel tracking.

To adjust, increase the drive level for a color that appears too weak in the test pattern (i.e., one that is less than 73). Try not to reduce a drive, as low settings can reduce overall projector brightness. Also keep in mind that setting a drive level over 73 will limit the number of discernible grays and produce an uneven color temperature across the grayscale.

NOTES: 1) Always try to achieve the desired effect by first increasing the drive level for the color judged to be weak. If the drive level for that color is already at 73, then decrease the contrast level for one or more of the other colors. 2) If you want to adjust each color individually, you can connect only one signal cable — red, green or blue — at a time.

When working with multiple projectors, you may want to use the RS-232 ports to chain the projectors together in a network that you control from either a keypad or a computer/controller (see 2.9, Serial Port Connections). Or you may prefer that each projector stands alone, in which case you will probably use a single IR remote keypad. In either case, you can switch back and forth between broadcasting to all projectors or controlling each projector individually.

Make sure you have assigned a unique projector number to each projector

present on the network — this number will be required in order get the exclusive attention of an individual projector. To assign a projector number:

Press

and select the Preferences icon. In the Preferences menu, scroll down to "Projector#" and enter a three-digit number (000 to 999) to identify the current projector. Press

to accept the entry and return to the main menu.

Repeat for each projector, using a unique three-digit number for each. Once every projector has its own number, you can begin to control the network.

If you are using an IR remote, press

to display an editable window. Enter the three-digit number you have assigned to the projector you wish to control. All keypad commands will then affect this projector exclusively until you press

again and enter a different number, or

until you switch to broadcast mode (below).

If you are using a wired remote keypad (optional) in a network of projectors, make sure that the projector to which the keypad is connected has its “Broadcast Keys” option checked. Press

to bring up the editable box. Enter the three-digit number assigned to the projector you want to control — keypad commands will now affect only the desired

Observe and follow all warnings and instructions marked on

the projector. The exclamation point within the equilateral triangle alerts the

user to important operating and maintenance (servicing) instructions in the literature accompanying the projector.

The lightning flash and arrowhead symbol within the equilateral triangle alerts the user to uninsulated "dangerous voltage" within the projector's enclosure that may be of sufficient magnitude to constitute a risk of electric shock.

3URMHFWRU /RFDWLRQ

Operate the projector in an environment which meets the operating range

specifications in Section 5, Specifications. Do not operate the projector close to water, such as near a swimming pool.

Do not place the projector on an unstable cart, stand or table. If the projector is to be ceiling mounted, only use an Electrohome-approved ceiling mount fixture.

A projector and cart combination should be used with care. Sudden stops, excessive force, and uneven surfaces may cause the projector and cart combination to overturn.

The arc lamp operates at a very high temperature and pressure. Failure to allow the lamp to sufficiently cool prior to handling could result in an explosion causing personal injury and/or property damage. After turning the projector off it is important that you wait at least five minutes before unplugging it. This provides enough time for the internal lamp cooling fans to cool the lamp and to automatically shut off. Cool completely before handling.

Replace the rear filter every 1000 hours or sooner. If this filter is not replaced, air flow may become restricted and cause the projector to overheat.

Do not allow anything to rest on the power cord. Locate the projector where the cord cannot be abused by persons walking on it or objects rolling over it.

Operate the projector at the specified voltage. Do not overload power outlets and extension cords as this can result in fire or shock hazards.

The projector is equipped with a three wire plug having a third (grounding) pin. This is a safety feature. If you are unable to insert the plug into the outlet, contact an electrician to have the outlet replaced. Do not defeat the safety purpose of the grounding-type plug.

Before unplugging the power cord, make sure the internal lamp cooling fans have shut off. The fans automatically shut off when the projector has adequately cooled down.

Slots and openings in the projector provide ventilation. To ensure reliable operation of the projector and to prevent overheating, these openings must never be blocked or covered. The projector should never be

placed near or over a radiator or heat register. The projector should not be placed in an enclosure unless proper ventilation is provided.

Do not push objects of any kind into the projector through the ventilation openings. They may touch dangerous voltages or short-out components resulting in a fire or shock hazard. Do not spill liquids of any kind into the projector. Should an accidental spill occur, immediately unplug the projector and have it serviced by a qualified service technician.

If any of the following conditions exist, unplug the projector from the power outlet and refer service to qualified service personnel.

• The power cord has been damaged.

• The internal cooling fans do not come on when the projector is first turned on.

• Liquid has been spilled into the projector.

• The projector has been exposed to excessive moisture.

• The projector does not operate normally.

• The projector has been dropped or the case has been damaged.

• Projector performance has deteriorated.

Do not attempt to service the projector yourself. All servicing must be performed by a qualified Electrohome service technician. If replacement parts are required, it is important that only Electrohome-approved parts are used. Other parts may result in fire, electric shock or risk of personal injury.

Clean the projector when required. Before cleaning, always unplug the projector from the power outlet.

To avoid the risk of scratching the lens, only clean the lens if absolutely

required. A small amount of dust on the lens will have very little effect on picture quality. If the lens must be cleaned, use a DRY soft cotton cloth. Rub gently in a circular motion.

It is important to never touch the sapphire (glass) surface of the lamp, as the oil

imprint will seriously degrade lamp performance. However, should you accidentally touch the surface of the lamp, clean gently with a lint-free cloth moistened with isopropyl alcohol.

Clean the case with a soft dampened cloth. Use a mild commercial cleaner. Do

not use liquid or aerosol cleaners.

The IR Remote Keypad uses four AA size, 1.5V batteries (preferably aklaline). To install new batteries, open the battery compartment at the back side of the keypad by pulling on the raised portion of the cover as shown (Figure 4.1)

Remove the old batteries and properly discard. Place the new batteries in the compartment, orienting the positive/negative of each battery according to the labels in the compartment.

Or, if you prefer, you can dispose of the old lamp as described below:

1. For safe disposal, first relieve the pressure within the lamp module by opening the lamp gas valve and allowing the Xenon gas to escape. This valve lies beneath a small plastic seal protruding from the right end the lamp (i.e., the end opposite the glass surface). To open the valve:

2. Place the lamp module on a stable worksurface, with the glass lens surface facing left as shown in Figure 4.6.

3. Locate the plastic seal protruding from the right side of the module— the side opposite the lens (Figure

tighten the valve screw until the lamp module begins to hiss, signifying that the lamp seal is broken and the Xenon gas is escaping. Note that although this gas is not harmful to the atmosphere, always direct this surface of the module away from you and others.

5. Wait for the hissing to subside, which may take up to 20 seconds or more.

6. Dispose of lamp with regular trash. Keep in mind that the integral lamp timer contains a small amount of mercury—this mercury must be treated as hazardous waste if discarded in volume.

Grasp the lens assembly near the point where it enters the projector and slowly

unscrew (counter-clockwise) until the assembly is free from the projector. Use both hands and take care not to touch the lens surface, which is easily damaged. Set aside.

Make sure the new lens is protected by the lens cap. Install the new lens in the

projector by carefully screwing the assembly into the projector just until snug. If the lens assembly seems difficult to turn, it may be cross-threaded. Carefully remove and try again. Use both hands and do not force or over-tighten.

Remove lens cap and reposition the projector closer to or further from the screen

as necessary for the screen and new lens type. For example, if using a 1.2:1 lens,

[

throw distance should be roughly equal to 1.2

the screen width. Adjust vertical

offset as necessary so that display is rectangular.

two for sync. For three-wire RGB, the green wire usually provides sync. (See TTL Video).

A common asynchronous data transmission standard recommended by the

Electronics Industries Association (EIA). Also called serial communication. A relatively rare asynchronous data transmission standard in which balanced

voltage is specified. RS-422 is used for exceptionally long distances only. The output from certain video tape players and video equipment. S-Video

separates sync and luminance from color information, typically producing a higher quality display than composite video.

The horizontal or vertical frequency at which images are generated.

One horizontal line on the display.

A video output format of some video tape and disk players (used primarily in

France). SECAM (Sequential Couleur á Mémoire) signals are similar in resolution and frequency to PAL signals. The primary difference between the two standards is in the way color information is encoded.

A slidebar is a graphical display of an adjustable setting. The numerical setting

usually represents a percentage. The device, such as a computer or VCR, connected to the projector for display.

A source is identified as numbers. Sources have corresponding channels recognized by the projector.

See Channel Number.

See Channel.

The diameter of the smallest dot that can be generated by a CRT projector.

VistaGRAPHX 5000 has a fixed spot (pixel) size. A signal selector that can be connected to a projector for the purpose of adding

more sources. This term refers to the part of the video signal that is used to stabilize the picture.

Sync can occur in three forms:

"Composite sync": the horizontal and vertical components are together on one cable.

"Sync-on-green": the sync is part of the green video.

"Separate sync" or "H.SYNC and V.SYNC": the horizontal and vertical components of the sync are on two separate cables.

The duration of each sync pulse generated by a computer. The sync width is part

of the blanking time. A type of RGB video with digital characteristics.

A wire connecting a single video source to a display device, such as a projector,

must be terminated by a resistance (usually 756 for video).

The distance between the front feet of the projector and the screen. Also called

"Projector-to-Screen Distance”. Balance of red-to-green necessary for realistic representation of NTSC signals.

The ability of a projector to synchronize to inputs with frequencies within a

specified range. The frequency at which images are generated. Vertical frequencies vary amongst

sources. Also called vertical scan rate. The difference between the vertical height of the projector lens and the vertical

height of the display. The signal that is used by display devices (such as projectors) to generate an

image. This term also refers to the output of video tape/disk players and computers.

A device that converts NTSC 3.58, NTSC 4.4, PAL, PAL-N, PAL-M or SECAM

Screens do not reflect equally in all directions. Most light is reflected in a

conical volume centered around the "line of best viewing". Maximum brightness is perceived if you are within the viewing cone defined by the horizontal and vertical viewing angles.

The color temperature of white used by the projector.

The area of an image that is white only. For example, a full white field is an

image that is white everywhere. A 10% white field is a white area (usually rectangular) that occupies 10% of the image; the remaining 90% is black.

See YUV video.

A high-end signal suitable for broadcast. YUV video (also called component

video) by-passes the VistaGRAPHX 5000 video decoder. The adjustment of image size through the use of a zoom lens.

Always consult this Appendix when planning a projector installation. See 2.3, Projector Position and Mounting for additional information.

The correct throw distance for an installation depends on the screen size and projector lens type present — the larger the image, the greater the distance you must allow between the projector and screen. Once you know the screen size and lens type present, you can calculate the throw distance required in an installation

by using the appropriate formula as found in this appendix.

Note that throw distance is measured perpendicular to the projector front feet and the screen but not necessarily parallel to the floor — i.e., the projector and screen may both be inclined.

Pre-calculated throw distances for the complete range of lens types and screen sizes appear in the charts and graphs on the following pages. Refer to these examples to quickly determine the proper throw distance for your installation.

NOTE: The variable operating ranges for zoom lenses appear in graphs only. Formulae and charts do not apply.
