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, such as when a shaft of 
light from a window or floodlight falls on the image. Images may...

Figure 2.1. Estimating Throw Distance 
 
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 –...

Figure 2.3. Lens Vertical Offsets 
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 
percentage of half the image width...

Lifting and transporting the projector – The projector is light enough to lift and 
transport a short distance. Use the indentations on the bottom of the projector as a 
guide for hand placement, which makes carrying the projector easier. 
When transporting the projector a long distance, use a stable cart or ask someone for 
help. 
Mounting  
There are several methods for...

Adjusting projector height  
You can modify the height of the 
projector to remedy a slightly 
unlevel mounting surface by 
adjusting the three feet threaded 
into the bottom chassis. Turn each 
foot clockwise or counter-
clockwise until the project is level 
on all sides. (Figure 2.7.)  
 
 
 
NOTE: The front of the projector can be 
raised up to 10 degrees.    (Figure 2.8.)...

Sources connect to the Input Panel located at the back of the projector. See Figure 
2.10. 
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. The DVI-I connector at 
INPUT 2 accepts digital or analog display signals from 
a computer. Connect analog composite video at 
INPUT 3 or S-video at...

NOTES: 1) If for some reason the projector fails to recognize a signal as an RGB 
signal, specify the Color Space option within the Image Settings menu. See 3.7, 
Adjusting the Image. 2) To connect YPbPr signals–such as from DVDs or analog HDTV 
sources–to 
INPUT 1, use the red, green and blue BNCs as described in YPbPr Signals 
(below). 3) Use the computer cable provided,...

to the projector. When connecting devices that transmit an analog video signal such as 
VCRs, laptops, and PCs use the cable...
