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 guidelines:
•

Position the projector on a flat surface at a right angle to the screen. IN2124

must be at least 45.3” (1.2m) from the projection screen, and IN2126 must be

at least 55.4” (1.4m) from the projection screen.

•

If you are installing the projector on the ceiling, we strongly recommend using

InFocus approved ceiling mounts for proper fitting, ventilation and installation.

Refer to the installation guide that comes with the InFocus Ceiling Mount Kit

(p/n PRJ-MNT-UNIV) for more information. The warranty does not cover

any damage caused by use of non-approved ceiling mount kits or by installing

in an improper location. To turn the image upside down, see “Ceiling mount”

on page 27. We recommend using an InFocus authorized ceiling mount.

•

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

from the lens of the projector to the screen and the video format determine

the size of the projected image.

•

The image offset for IN2124 is 115% +/-5%. This means that if you have an

image 60 inches (1.5 meters) tall from a table-mounted projector, the bottom

of the image will be 9 inches (22.9 cm) above the centerline of the lens. The

image offset for IN2126 is 113% +/-5%. This means that if you have an image

60 inches (1.5 meters) tall from a table-mounted projector, the bottom of the

image will be 7.8 inches (19.8 cm) above the centerline of the lens.
