Solving Problems
The image contains static or noise.
■
Make sure the correct
Input Signal
is selected in the Video menu
(see page 77).
■
If you’re using a computer cable longer than 6 feet (2 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 laptop
computer and the projector, turn off the laptop’s LCD display.
The image is blurry.
■
There may be dirt or smears on the lens. Clean the lens as
described on page 94.
■
Adjust the focus using the focus ring.
■
Make sure the lens is not fogged by condensation. You may need
to wait before using the projector after moving it from a cold
environment to a warm environment.
■
Adjust the
Sharpness
setting on the Video menu (see page 76).
When you change video settings, you should be able to see the
effect on the screen immediately. If you’re projecting from a
computer, you may also need to adjust the tracking and sync as
described in the next section. If you don’t like the new settings,
you can always select
Reset
to return to the factory default
settings.
