Projector Placement Options
When projecting from the front, you should place the projector 
directly in front of the center of the screen, facing the screen squarely. 
The center of the lens should be about level with the bottom of the 
screen.
If you place the projector below screen level, you may need to tilt it up 
by extending the front adjustable foot. Tilting the projector causes the 
image to become “keystone” shaped, bu/t you can correct the 
distortion (see page 41).

							Setting Up the Projector25
You can also install the projector in three other viewing setups: ceiling 
projection, rear projection onto a semi-transparent screen, or 
rear/ceiling projection.
To project from overhead, you’ll need the optional ceiling mounting 
hardware (see page 15). You’ll also need to select the appropriate 
Projection setting in the projector’s Extended menu to orient the 
image correctly (see page 61).
Connecting to a Computer
You can connect the projector to a Windows computer using the 
projector’s 
TypeB USB port. This lets you carry a lightweight cable 
with you when you transport the projector (see page 26).
You can connect the projector to any computer that has a standard 
video output (monitor) port, including desktop models, PC notebook 
computers, Macintosh PowerBook
® and iBook® computers, and 
hand-held devices. See page 27 for instructions.
To play sound through the projector, connect an audio cable (see 
page 34).
You may be able to use your remote control as a wireless mouse when 
projecting from a computer (see page 50).
