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 39. We recommend
using an authorized ceiling mount.
• 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 45.
• The image exits the projector at a given angle. This 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 132.9% 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 3.29’ above the center of the lens.
• See “Connecting a video device” on page 16 for additional information
on 16:9 and 4:3 modes.
