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 4.9 feet (1.49m) 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. InFocus recom-

mends using an authorized InFocus ceiling mount. The Ceiling Mount

Kit is sold separately; see “Optional Accessories” on page 40.

• Position the projector the desired distance from the screen. The distance

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

video format determine the size of the projected image. The top illus-

tration to the right shows three projected image sizes. For more infor-

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

size” on page 40.

• The image exits the projector at a given angle. The image offset is

112.2% when the projector is in 4:3 mode (default mode). This means

that if you have an image 10’ high, the bottom of the image will be 1.22’

above the center of the lens.

• This image offset is 124.7% when the projector is in 16:9 mode. This

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

be 2.47’ above the center of the lens.

• See “Connecting a video device” on page 11 for additional information

on 16:9 and 4:3 modes.
