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 44.
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 60).
If you're using a composite, S-video, or component video source
■
with 480i signals, turn on the
menu (see page 60).
If you've used the Keystone adjustment, you may need to decrease
■
the
setting in the Image menu (see page 58).
Sharpness
■
If you're projecting from a computer, make sure its signal is
compatible with the projector. See page 97.
