Make sure your computer's resolution setting is correct. See the
■
compatible video formats listed on page 110.
You also may need to modify existing presentation files if you
■
created them for a different resolution. See your software
documentation for specific information.
■
If you're projecting a widescreen computer image, adjust the
setting (see page 71), if necessary.
Resolution
■
If you're projecting an image from a computer with dual display
activated, turn dual display off.
The image isn't square, but keystone-shaped.
If the image isn't evenly rectangular, adjust its shape as described on
page 50.
The image contains static or noise.
■
If you're using a computer cable longer than 6 feet (1.8 meters),
or an extension cable, the image quality may be reduced.
Keep your computer and video cables away from the power cord
■
as much as possible to prevent interference.
The video signal may be split between the computer and the
■
projector. If you notice a decline in the projected image quality
when the image is displayed simultaneously on your notebook
computer and the projector, turn off the notebook's LCD display.
Make sure the correct input signal is selected in the Signal menu
■
(see page 72).
If you're using a composite, S-Video, or component video source
■
with 480i signals, turn on the
menu (see page 72).
■
If you've used the Keystone adjustment, you may need to decrease
the
setting in the Image menu (see page 70).
Sharpness
■
If you're projecting from a computer, make sure its signal is
compatible with the projector. See page 110.
