source.
If you are installing the projector on the ceiling, refer to the
•
Ceiling Mount Installation Guide that comes with the Ceiling
Mount Kit for more information. To turn the image upside
down, see "Ceiling" on page 34. The Ceiling Mount Kit is
sold separately; see page 48.
2 Position the projector the desired distance from the screen.
The distance from the lens of the projector to the screen and
•
the zoom lens setting determine the size of the projected
image. Table 1 shows example projected image sizes and
minimum and maximum distances to the screen.
The formulas for distance to the screen are:
Max distance (ft) = diagonal image size (ft) ÷ .541
Min distance (ft) = diagonal image size (ft) ÷ .716
