Proper installation of your projector will ensure the quality of your display. Whether 
you are installing a projector temporarily or permanently you should take the 
following into account to ensure your projector performs optimally. 
Choose the installation type that best suits your needs: front or rear screen, floor 
mount or inverted mount.

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 one. The main 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...

output with a 4:3 aspect ratio onto a 10-foot (3m) high screen, the width of the screen 
must be at least 13.3feet (4m). 
The high brightness of this projector is well suited for locations where ambient 
lighting might be considered less than ideal for projection. A typical room with ceiling 
lights and windows rarely requires special attention. Contrast ratio in your images will 
be noticeably reduced only if light directly strikes the screen,...

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 (lens center) by...

The horizontal position of the image can be offset – that is moved to the left or right 
of lens center, by adjusting the fully motorized lens mount through software. The 
amount of horizontal offset available depends on the lens installed and if the image 
has already been vertically offset. Horizontal offset can also be expressed as the 
percent of half the image width – the number of pixels of shift to one side of lens 
center. Refer to Figure...

Mounting  
There are several methods for mounting the projector. Depending on your chosen 
installation, one method may be more suitable than another. 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 during a 
presentation or from site to site. It is recommended you lock the wheels on a cart, 
when it’s in...

Sources connect to the Input Panel located at the back of the projector. See Figure 2.6. 
The upper right corner (
INPUT 1) typically accepts an RGB signal from an external 
analog RGB source, or it can also be used for YPbPr signals or additional video 
sources. Just beside these BNCs, the DVI-I connector (
INPUT 2) accepts digital or 
analog display signals from a computer. Connect analog composite video at 
INPUT 3 
or S-video at 
INPUT 4...
