Solving Problems
The image or parts of the image are blurred or not in focus.
■
Adjust the focus using the focus ring.
■
Adjust the Brightness, Contrast, Sharpness, and Gamma settings
on the Video menu. If you’re viewing a computer image, also try
adjusting the
Tracking
and
Sync
buttons on the projector’s
control panel.
When you change video settings, you should be able to see the
effect on the screen immediately. If you don’t like the new
settings, you can always select
Reset
to return to the factory
default settings.
■
Try pressing the
Auto
button on the remote control or the
Enter
button on the control panel to automatically reset the video
settings.
■
There may be dirt or smears on the lens. Clean the lens as
described on page 77.
The image vibrates, flickers, or has vertical lines.
If you’re projecting from a computer, try pressing
Auto
on the remote
control or
Enter
on the control panel. This resets the computer
display settings automatically.
If that doesn’t work, adjust the
Tracking
and
Sync
using the buttons
on the control panel. Hold down the button to change the setting
until your image looks correct. It is best to project a gray screen (or the
screen you see when you exit Windows) when you adjust these
settings.
You can also change the Tracking and Sync settings through the
Video menu (see page 64).
The image quality is poor on a laptop computer.
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 LCD display.
note
Images will be projected more
vividly if you adjust the
Tracking
before the
Sync
.
