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. The 

projector must be at least 4.9 feet (1.5m) 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 

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

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

•

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 image exits the projector at a given angle. IN1100 image offset is 

115%; IN1102 image offset is 112.4%. This means that if you have an 

image 10’ high, the bottom of the image will be 1.5' (IN1100) and 1.24' 

(IN1102) above the center of the lens.
