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...

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...

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...

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...

The horizontal position of the image can also be offset; that is moved to the left or right of optical 
center, by adjusting the motorized 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. Ta b l e

2.2.4Mounting
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, such as a table or cart. Carts are useful when 
the projector has to be moved often. Lock the wheels on a cart, when it is in position, to prevent 
accidental movement during a presentation.
CEILING MOUNT
The projector can be inverted and suspended from the ceiling using a...

ADJUSTING TILT
1. Before adjusting tilt, ensure the projector is centered. NOTE: Check with site personnel for the 
degree of screen tilt, or measure this incline with a protractor at the screen. 
2. Then tilt the projector to closely match the screen tilt angle by extending or retracting the 
projector’s 3 adjustable feet. 
NOTE: 1) For an ideal installation, the lens surface should be centered and parallel to the...
