Positioning the Projector

Follow these guidelines:
Place the projector on a sturdy, level surface between
2.8 and 48.3 feet from the screen. Image size generally
increases with distance, but may vary depending on the
position of the zoom ring and other settings.
5.8 to 9.5 ft
29.8 to 48.3 ft
Place it within 10 feet of an electrical outlet or extension
cord and 5 feet of your computer or video source.
Allow space for ventilation around and under the projector.
To avoid a keystone shaped image (an image that is wider
on one side), place the projector directly in front of the
center of the screen, facing the screen squarely.
If possible, place the projector level with the bottom of the
screen.
If you place the projector too far below the screen, you may
have to tilt it up by extending the front adjustable foot (see
page 7). This causes the projected image to lose its shape, but
the projector automatically compensates. If the image is still
not square, adjust it manually by pressing the
buttons (see page 7) or using Quick Corner (see page 8).
If you place the projector higher than the bottom of the
screen, the image will be square, but it won't fill the screen.
Calculating Image Size and Projection
Distance
Use the formulas below to find out how large the image will
be when you know the distance from projector to screen, or to
find out how far from the screen to place the projector if you
want an image of a certain size. Since you can change the
image size by adjusting the zoom, formulas are given for
calculating both minimum and maximum sizes.
Note: Formulas given here apply only when the image is not
tilted. If you tilt the image up by extending the projector's foot or
using electronic keystone correction, your image size may vary.
To determine the diagonal size of an image (in inches) when
you know the projection distance:
2.8 to 4.7 ft
Distance
from screen
Keystone
Maximum diagonal size =
(projection distance[inches] x 2.54 x 0.32827 + 1.6767)
Minimum diagonal size =
(projection distance[inches] x 2.54 x 0.203 + 1.077)
To determine the projection distance (in inches) when you
know the diagonal size of the screen image:
Maximum projection distance =
((diagonal size[inches] x 4.92611) - 5.30542) / 2.54
Minimum projection distance =
((diagonal size[inches] x 3.04627) - 5.10769) / 2.54

Connecting the Projector

You can connect the projector to two computer sources or
four video sources—up to a total of four sources. You can
include an independent sound channel for each source. (See
the User's Guide for complete setup instructions.)
Note: The preview feature lets you see all the sources at a glance,
so you can easily switch to the one you want. See page 5.
Types of Connections
The following connections are possible, depending on the
signal your equipment generates and its available output ports.
Computer equipment
Output signal
Analog RGB video
DVI
Video equipment

Composite video
S-video
Component video
RGB video
Note that the projector's
input signals. If you're connecting to one of these ports, you'll
need to make sure that the correct input signal setting is
selected or your image won't display properly.
Playing Sound Through the Projector
You can play sound through the projector's speaker system or
attach an external speaker system.
To play sound through the projector, use one of the following
cables that came with your projector:
