■ Make sure the correct input signal is selected in the Signal menu
(see page 59).
■ If you’ve used the Quick Corner or Keystone adjustment, you
may need to decrease the
Sharpness setting in the Image menu
(see page 57).
■ If you’re projecting from a computer, make sure its signal is
compatible with the projector. See page 109.
■ Press the Auto button on the remote control or the Enter button
on the projector to reset the projector’s Tracking, Sync, and
Position settings. If further adjustment is needed, you can
fine-tune the
Tracking and Sync settings manually using the
Signal menu, as described on page 59.
The image is blurry.
■ There may be dirt or smears on the lens. Clean the lens as
described on page 74.
■ Adjust the focus using the focus ring (see page 30).
■ If the projector is angled sharply toward the screen, it may not be
possible to focus the entire image. Move the projector to position
it more directly in front of the screen.
■ Lower the projection angle to reduce the amount of keystone
correction required.
■ Make sure the projector is within the proper range (projection
distance) from the screen (see page 106).
■ 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.
■ If you’re projecting from a computer, you may need to adjust the
tracking and sync settings as described in the next section.
note
You must be projecting an
image for the
Auto button
to have any effect. It works
only with computer images
projected through the VGA
port.
