Careful consideration should be given as to how and where the projection
Considerations system is installed. Although the projector offers high performance, the final
display quality could be compromised if the projector is not installed properly.
This subsection discusses the considerations you should make before
proceeding with afinal installation. These considerations include the
installation type (floor, ceiling, rear), screen size and type, room lighting, and
ventilation.

INSTALLATION &SETUP
Screen Type ●Screen type is avery important factor when designing aprojection system.
Inexperienced users or installers should always consult their dealer when
deciding on screen type. The following guidelines may be helpful to
understand the differences between screen types.
Front Screen Installations
There are two basic screen types: flat and curved. The choice between aflat
screen versus acurved screen is dependant on audience viewing angle and
screen gain. There is always atrade-off between viewing angle and gain.
Viewing angles for both screen types are illustrated in Figures 2-1 and 2-2.
Flat screens offer again of about 1with aviewing 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.
Figure 2-1. Audience Coverage with Flat Screen
Figure 2-2. Audience Coverage with Curved Screen
Curved screens have gains larger than 1and 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 aconical volume or “viewing cone”. Audiences within
the viewing cone see abrighter image than that from an equal area on aflat
screen. Audiences outside the viewing cone see adimmer image.

IINSTALLATION &SETUP
To summarize, curved screens are better suited for brightly lit rooms where the
audience is situated within the viewing cone. Flat screens are best suited when
awide viewing angle is required and ambient room lighting (near the screen)
is low.
Note: Screen Gain is defined in Appendix A, Glossaty.
Rear Screen Installations
There are two basic types of rear screens: diffised and optical. Adiffused
screen has asurface which spreads the light striking it. Purely diffused screens
have again of less than 1. The main advantage of the diffused screen is its
wide viewing angle, similar to that of aflat 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. Aviewing
cone, similar to that of acurved 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 awide viewing angle is required but there is low ambient room lighting.
Screen Size and ●Screen size and throw distance are interrelated. See Appendices Fand G. As
Throw Distance screen size increases, the distance between the projector and the screen also
increases. During projection room design, make sure that the room can
accommodate the required position of the projector for the screen size you
need.
Screen Size
Screen sizes vary according to model and lens type. See Appendices Fand G.
Choose ascreen size which is appropriate for your application. If the projector
will be used to display text information it is important that the image size
allows the audience to clearly resolve all text. The eye usually sees aletter
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 not be legible at adistance even
though it is projected sharply and clearly on the screen.
To fill ascreen with an image, the aspect ratio of the screen must be equal to
the aspect ratio of the image. The aspect ratio of an image is the ratio of its
width to its height. Standard video from aVCR has a4:3 or 1.33:1 aspect
ratio. For example, to display aVCR output with a4:3 aspect ratio onto a10
foot (3m) high screen, the width of the screen must be at least 13.3 feet (4m).
Note: Screen size is ofien specified as diagonal size. Screensspecified by,
diagonal size have aspect ratios of 4:3. Screens with other aspect ratios are
not typically specij7ed by diagonal size.

Throw Distance
INSTALLATION &SETUP
The throw distance (projector-to-screen distance) must be determined for every
new installation. Throw distance, the distance between the projector’s center
lens and the center of the screen, is based on screen size. As screen size
increases, the distance between the projector and the screen increases. Make
sure that the room can accommodate the required position of the projector for
the chosen screen size.
Once your screen size is known you can determine the required throw distance
for your projector model and lens by using the formulas in Appendix Gand
tables in Appendix F.
Notes: 1) Calculated values are for reference only. It is good practice to
simulate the setup to determine the necessary throw distance. 2) Display size is
aflected by input signal characteristics. Once the projector is set, use the Size
function to fine tune display size.
Throw distance and projection angle: Keep in mind that the ability to properly
focus all areas of the image is limited if asignificantly tilted projector is too
close to the screen.
Lighting ●Proper lighting is another important factor when designing aprojection room.
Visiting amovie theatre can give you an idea of what makes agood projection
environment. All walls, floors and furnishings are dull colored and non-
reflectively finished. Every effort should be made to create the best
environment for your system.
When designing aprojection room, try to avoid white, reflective ceilings and
non-directional lighting such as fluorescent lights. The white ceiling spreads
the light which makes the room appear brighter. You want to keep the
lighting and reflections to aminimum. If it is not possible to keep fluorescent
lights off, consider using parabolic reflectors (“egg crates”) to direct light down
to the floor and away from the ceiling. Spot lighting (incandescent) is abetter
way to obtain illumination. Installing light dimmers or rheostats allows you to
control your lighting environment.
Outside windows are undesirable in any projection environment. Asmall
crack between curtains on asunny day can severely wash-out an image. Make
sure that curtains are opaque and fit snugly. Some curtains can provide up to
100 percent blockage of outside light. Pay close attention to the curtain
material facing inside the room. It should have amatte finish.
Even with no external light at all, reflections from room surfaces can degrade
the image. Light from the screen should be absorbed by surfaces so that it
will not be reflected back to the screen. Keep reflective surfaces to a
minimum.

Other
Considerations
2-6
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 has allowed 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.

●Here are some other considerations and tips which can help you improve the
design of your projection system.
❑
❑
Proper ventilation is important. 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. Keep 35 mm slide
projectors at least 2feet away from the projector. Even if both are not used
at the same time, the magnetic fields created by the slide projector can
cause permanent magnetization of the projector.
