Positioning the projector

To determine where to position the projector, consider the size and shape of 

your screen, the location of your power outlets, and the distance between 

the projector and the rest of your equipment. Here are some general guide-

lines:

•

Position the projector on a flat surface at a right angle to the screen. The 

projector must be at least 3 feet (0.9m) from the projection screen.

•

Position the projector within 10 feet (3m) of your power source and 

within 6 feet (1.8m) of your video device (unless you purchase exten-

sion cables). To ensure adequate cable access, do not place the projector 

within 6 inches (.15m) of a wall or other object.

•

If you are installing the projector on the ceiling, refer to the installation 

guide that comes with the Ceiling Mount Kit for more information. To 

turn the image upside down, see “Ceiling” on page 33. We recommend 

using an authorized ceiling mount. The Ceiling Mount Kit is sold sepa-

rately; visit our website for more information.

•

Position the projector the desired distance from the screen. The dis-

tance from the lens of the projector to the screen, the zoom setting, and 

the video format determine the size of the projected image. For infor-

mation about image sizes at different distances, see “Projected image 

•

For the standard lens that comes with the projector, the image exits at a 

given angle. However, the lens shift feature makes the image offset 

variable. The image offset is 100% at a 10:1 ratio when the projector is in 

16:10 mode (default mode). This means that if you have an image 10’ 

high, the bottom of the image will be at the center of the lens. 

•

The image offset is 50% when the lens shift is at a 1:1 ratio. This means 

that if you have an image 10’ high, the bottom of the image will be 5’ 

below the center of the lens.
