The image isn’t square, but trapezoid-shaped.
■ Make sure the projector isn’t placed off to one side of the screen,
at an angle. Place the projector directly in front of the center of
the screen, facing the screen squarely.
■ If you’ve tilted the projector upward by extending the legs, the
image will be broader at the top. Hold down the
+ or – side of the
Keystone button on top of the projector until the image is
square.
The image contains static or noise.
■ If you’ve connected a device to the Computer 2/Component
Video port, make sure the
BNC option in the Setting menu is
correct. See the Administrator’s Manual.
■ If you’re using a computer cable longer than 6 feet, the image
quality may be reduced.
■ Keep your computer and video cables separated 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;
see your laptop’s manual for instructions.
The image is blurry.
■ There may be dirt or smears on the lens. Clean the lens as
described in the Administrator’s Manual.
■ Adjust the focus using the focus ring.
■ Adjust the Sharpness setting in the Video menu (see the
Administrator’s Manual). 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.
