Solving Problems
The image isn’t square, but trapezoid-shaped.
If you’ve tilted the projector upward by extending the foot, the image
will be broader at the top. If it is tilting downward, it will be broader
at the base. To correct this, hold down the
Shift
button on the
projector’s control panel and press the top or bottom
Keystone
button until the corners of the image are square.
The image contains static or noise.
■
If you are projecting from a 480i or 575i input source, turn on the
Noise Reduction
feature in the Advanced menu to reduce visual
noise. See page 33.
■
Make sure the
Video Signal
,
Input A
, or
Input B
options in the
Advanced menu are correct. See page 33.
■
If you’re using a computer cable longer than 6 feet (2 meters), or
an extension cable, the image quality may be reduced. Also, 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 40.
■
Adjust the focus using the focus ring or display the test pattern by
pressing the
Pattern
button.
■
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.
