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 13.3feet (4m). 
The high brightness of this projector is well suited for...

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...

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...

NOTES: 1) If for some reason the projector fails to recognize a signal as an RGB 
signal, specify this Color Space option within the Image Settings menu. See 3.5 
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). 
 
Connect a YPbPr signal (component video) to INPUT 1 or INPUT...

INPUT 3 and INPUT 4 provide simultaneous connection of both a composite video 
source (
INPUT 3) and an S-Video source (INPUT 4). See Figure 2.9.  
 
Figure 2.9.Connecting Composite or S-Video sources 
Use the DVI-I connector at INPUT 2 to connect either analog or digital video devices 
to the projector. When connecting devices that transmit an analog video signal such as 
VCRs, laptops, and PCs use the DVI cable provided with the projector....
