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’ (1.5m) from the projection screen.
• Position the projector within 10’ (3m) of your power source and within 6’
(1.8m) of your video device (unless you purchase extension cables). To ensure
adequate cable access, do not place the projector within 6” (.15m) of a wall or
other object.
• Position the projector to 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. This image offset is 115%. This
means that for an image 10’ high, the bottom of the image will be 1.15’ above
the center of the lens.
