Throw DistanceThrow distance is the distance measured from the front of the projector to the screen. 
This is an important calculation in any projector installation as it determines whether or not 
you have enough room to install your projector with a desired screen size and if your 
image will be the right size for your screen.
You can quickly estimate the throw distance by multiplying the width of the screen by the 
lens throw ratio; see...

Vertical and Horizontal 
Position
Proper placement of the projector relative to the screen will yield a rectangular, 
perfectly-centered image that completely fills the screen.
Ideally, the projector should be positioned perpendicular to the screen and in such a way 
that the lens center and screen center are aligned with each other, as shown in 
Figure 3-2.

If you find that you cannot raise or lower the image enough using mechanical vertical 
offset, you may need to make keystone adjustments or vertically shift the image using the 
on-screen display (OSD) controls, to compensate. For detailed instructions, refer to 
Using 
the On-Screen Menus on page 69.
If images remain keystoned or exhibit uneven brightness, the projector may simply be too 
high or low in relation to the screen. Relocate the...
