users or installers should always consult their dealer when deciding on screen
type. The following guidelines explain the differences between screen types.
)URQW#6FUHHQ#,QVWDOODWLRQV
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 2-4 and Figure 2-5 (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, although this difference may be negligible
given the ultra high brightness output from this projector.

)LJXUH#5081#$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: Vista
GRAPHX
10K lenses are designed primarily for use with flat screens.
However, the projector 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.

8VHU*V#0DQXDO
#43.#
508
,167$//$7,21#)#6(783
6FUHHQ#6L]H
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 6 to 40 feet diagonal, depending on the lens you are
ö
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 no matter how sharply and clearly it is
displayed.
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.
,GHDO#5RRP#/LJKWLQJ
The high brightness output of Vista
ö
GRAPHX
10K is certainly well suited for
locations where ambient lighting is less than optimum for projection, but there
are still many simple things you can do to optimize your installation.
Visiting a movie theater can give you an idea of what makes an ideal 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.
If it is not possible to eliminate fluorescent lights, consider using incandescent
spot lighting or parabolic reflectors ("egg crates") to direct light down to the
floor. Light dimmers or rheostats allow further control.
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 2-6 shows an
installation where poor screen placement allows too much unwanted light to
enter the screen. In Figure 2-7, the screen and the projector are positioned so that
unwanted light is minimized.

2WKHU#&RQVLGHUDWLRQV
)LJXUH#50:1#%HWWHU#6FUHHQ#3ODFHPHQW
Even with all lighting removed it is still possible that room reflections within the
room can slightly 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, keep reflective surfaces to a minimum.
Here are some other considerations and tips which can help you improve your
ö
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
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:
9LVWD
*5$3+;
8VHU*V#0DQXDO

50:
,167$//$7,21#)#6(783
◊ 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 2-8 shows two
examples of how audience coverage is maximized.

)LJXUH#50;1#6FUHHQ#/RFDWLRQV#IRU#0D[LPXP#$XGLHQFH#&RYHUDJH
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.
ö
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 you are using a 3.9:1 lens,
throw distance should be approximately 3.9
[
the screen width. Once you know
your screen size, you can estimate how far away the projector should be, as
shown in Table Chapter 2 -1.
,03257$17=
For exact placement in an
installation, always refer to the throw distance formula and/or graph for your
lens as listed in Appendix E.

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 precise throw
distance required. 3) Always use the throw distance information from Appendix E.
9HUWLFDO#3RVLWLRQ
The vertical position of the projector in relation to the screen also depends on the
ö
size of the screen and the lens type. Correct vertical position ensures that the
image will be rectangular in shape rather than keystoned (having non-parallel
sides) and that image focus and brightness both remain optimized.
Vertical position is offset—that is, the image can be moved—by using the
key. This displays the Lens menu, where both horizontal and vertical offset can
be adjusted with slidebars. Note that the range of adjustment depends on the lens
type you are using. See Table Chapter 2 -2 for the number of pixels by which
you can move an image using a specific lens. Refer to Figure 2-9 to see more
clearly how the pixel offset ranges affect the placement of your image in relation
to the vertical position of the projector.

NOTES: 1) If you cannot raise or lower the image enough for your installation,
or if the image becomes keystoned or exhibits uneven brightness, the projector is
probably too high or low in relation to the screen. 2) Recommended offset
ranges can be exceeded, however this may affect image quality. 3) Simultaneous
horizontal
offset can limit the range of vertical offset.

Some computers can provide
RS-422
serial communications (usually through a
plug-in adapter or external converter) rather than the RS-232 typically found on
most computers. RS-422 communication has differential transmits and receives
and is generally better suited for long distances than is RS-232 communication.
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 2-18.

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

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 2-22). When Keypad A has a different protocol than
Keypad B, 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 Vista
and Checking System Parameters
GRAPHX
10K Preferences menu. See
3.7, Adjusting
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
software protocol change, effective until the keypad is unplugged and plugged in
again (if a wired remote) or until a battery is removed (if an IR remote).
