■ If the image looks like or , the projector has been placed off to one side of the
screen and angled toward it. Face the projector straight ahead (instead of at the center of
the screen), then use the horizontal lens shift dial to center the image (see page 24).
■ If the image looks like or , use the remote control to access the Keystone
function to correct its shape (see page 25). Or press the u and d buttons on the
projector’s control panel.
Note: You won’t have to use the Keystone function to correct the image, as long as you place
the projector level (not angled up or down) and at a height between the top and bottom of the
screen. Then use the vertical lens shift knob to position the image. This produces the
best-looking picture.
The picture contains static or noise.

amplifier.

off your laptop’s LCD display (see page 57).

■ Make sure the lens is not fogged by condensation. If you’ve just moved the projector from
a cold environment, wait a couple of minutes before using it.

■ If you’re projecting from a computer, you may need to adjust the Tracking and Sync
settings (see page 40).
