Rear Ceiling
Wherever you set up the projector, make sure to position it squarely in front of the center of the screen,
not at an angle, if possible. If the projector cannot be centered in front of the screen, use lens shift to
reposition the image instead of using keystone correction for better image quality.
If you project from the ceiling or from the rear, be sure to select the correct
Projection
option in the
projector's menu system.

Projection Distance
The distance at which you place the projector from the screen determines the approximate size of the
image. The image size increases the farther the projector is from the screen, but can vary depending on
the zoom factor, aspect ratio, and other settings.
Use the tables here to determine approximately how far to place the projector from the screen based on
the size of the projected image. (Conversion figures may have been rounded up or down.)
You can also use the projector Throw Distance Calculator at
(U.S.) or
(Canada).
