Front Screen Installations
In front screen installations, the projector and audience are positioned in front of the screen, which can be flat
or curved.
Flat screens offer a gain of about 1.0 with a viewing angle just less than 180°. This type of screen reflects
incident light equally in all directions so the audience can see the display from various angles.
Curved screens have a gain greater than 1.0 with a viewing angle much less than 180°. This type of screen does
not reflect incident light equally in all directions; instead it is concentrated in a viewing cone. The audience
sitting within the viewing cone area will see a brighter image than those sitting just outside the area.
Rear Screen Installations
There are two basic types of rear screens: diffused and optical.
A diffused screen has a surface which spreads the light striking it. Purely diffused screens have a gain of less
than 1.0. 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 lightening.
Optical screens take light from the projector and redirect it to increase the light intensity at the front of the
screen. This reduces it in other areas. A viewing cone, similar to that of a curved front screen installation is
created. This type of screen is better suited for brightly lit rooms where the audience is situated within the
viewing cone.
Screen Size
Choose a screen size appropriate for your lens and application. If the projector will be used to display text
information, the image size must allow the audience to recognize all text clearly. The eye 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 will be
illegible at a distance no matter how sharply and clearly it is displayed.
Advantages Considerations
• Projector is completely hidden
• Usually good ambient light rejection.
• Requires less space behind screen than other rear
screen installations.
• Requires separate room or enclosure.
• Installation cost is usually higher.
• More involved to perform setup.

To fill a screen with an image, the aspect ratio of the screen should be equal to the aspect ratio of the image
(expressed as the ratio of its width to its height). Standard video from a VCR has a 4:3 or 1.33:1 aspect ratio.
For example, to display a VCR output with a 4:3 aspect ratio onto a 10-foot (3m) high screen, the width of the
screen must be at least 13.3 feet (4m).
Ambient Lighting
The high brightness of this projector is well suited for locations where ambient lighting might be considered
less than ideal. A typical room with ceiling lights and windows rarely requires special attention. Contrast ratio
in your images will be reduced if stray light directly strikes the screen. For example, when a shaft of light from
a window or floodlight falls on the image. Images may appear washed out and less vibrant. Avoid or eliminate
stray light sources directed at the screen.
Ventilation
The projector vents and louvers provide ventilation, both for intake and exhaust. Never block or cover these
openings. Do not install the projector near a radiator or heat register, or within an enclosure. To ensure
adequate airflow around the projector, allow free air exchange to the projector with a minimum clearance of
25cm (10”) on the left, right and rear sides of the projector from any walls or other obstructions. NOTE: Do
not obstruct the air exchange to the projector.
Other Considerations
Other considerations and tips to improve your installation:
• Keep the ambient temperature constant and below 40°C (104F). Keep the projector away from heating and/
or air conditioning vents. Changes in temperature may cause drifts in the projector circuitry, which may
affect performance.
• Keep the projector away from devices that radiate electromagnetic energy, such as motors and transformers,
slide projectors, speakers, power amplifiers, elevators, etc.
• Use a screen size appropriate for the venue but not larger than required. Installing a large screen in a small
room is similar to watching television at a close range; too large a screen can overpower a room and interfere
with the overall effect. As a rule, be no closer than 1.5 times the width of the screen.
2.2.3 Projector Position and Mounting
Throw Distance
Throw distance is the distance measured from your projector’s front feet 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 0.73:1 lens, throw distance would
roughly be 0.73 x screen width.
IMPORTANT: Use the lens and screen size to calculate the precise throw distance using the tables provided in
the Dealer Section of the Christie Website, PN 020-100221-XX. Due to lens manufacturing tolerances for
lens focal length, actual throw distance can vary ±5% between lenses with the same nominal throw ratio.

Vertical and horizontal position
The correct vertical and horizontal position of the projector in relation to the screen depends on the lens type
and the screen size. Ideally, the projector should be positioned perpendicular to the screen. This way, the image
will appear rectangular instead of keystoned (trapezoidal).
The vertical position of the image can be offset (that is moved above or below the optical axis) by adjusting the
motorized lens mount. The amount of vertical offset available depends on the type of lens installed in the
projector and can be limited if horizontal offset has been applied. Vertical offset can be expressed as the
percent of half the image height or the number of pixels of shift from lens center. Refer to Figure 2-9 - Vertical
Offset Examples for illustrated examples of vertical offset.
Table 2.1 and Table 2. 2 specify the vertical offset of each type of lens.
