Solving Problems
■
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.
■
If you’re projecting from a composite or S-Video source, check
the
Video Signal
setting in the Signal menu. In most cases, leave
it set at
Auto
. If you’re using a 60-Hz PAL video source, change
this setting to
PAL60
. See page 60 for details.
■
Make sure the cables are securely connected at both ends.
■
Select the correct resolution; see “Compatible Video Formats” on
page 100.
■
If you’re projecting from a computer, press the
Auto
button on
the remote control or the
Enter
button on the projector to adjust
tracking and sync automatically. If that doesn’t work, try
adjusting the
Sync
and
Tracking
settings in the Signal menu. See
page 59.
The image is blurry.
■ Adjust the focus using the focus ring.
■ Make sure the lens cap is off.
■ There may be dirt or smears on the lens. Clean the lens as
described on page 74.
■ 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.
■ Make sure the projection distance is within the range described on
page 16.
■ Adjust the
Sharpness
setting on the Image menu (see page 57).
You should be able to see the effect on the screen immediately.
