Interference or Distortion Appear in Images
• Are all the cables tied together?
• Is the image signal format setting correct?
Change the setting according to the signal for the connected equipment.
• Are “Phase” and “Tracking” settings adjusted correctly?
Press the [SOURCE] button on the projector’s control panel or the remote
control to search the signal again. If the images are not correct yet, adjust
“Phase”, “Tracking” settings in the “Autosync” menu manually.
• Is an extension cable being used?
If an extension cable is used, electrical interference may affect the signals.
Use the cables supplied with the projector to check if the cables you are
using may be causing the problem.
• Are the cables connected properly?
Check that all the cables required for projection are securely connected.
The Image is Truncated (Large) or Small
• Is “Aspect Ratio” adjusted correctly?
Adjust “Aspect Ratio” setting in the “Display” menu according to the signal.
• Is “Full screen” adjusted correctly?
Adjust “full screen” setting in the “Image” menu to “OFF”.
• Are “Horizontal Position” and “Vertical Position” adjusted correctly?
Adjust “Horizontal Position” and “Vertical Position” settings in the
“Autosync” menu.
• Is the correct resolution selected?
Set the computer so that the signals being output are compatible with the
projector. Please refer to “Compatible Input Signal List” in Page 29.
• Is the computer set for dual display?
If dual display is activated in the “Display Properties” of the computer’s
control panel, only about half of the image on the computer screen is
projected. To display the entire image on the computer screen, turn off the
dual display setting. See details in the computer video driver
documentation.
Image Colors are not Right
• Are the cables connected correctly?
• Is the image brightness adjusted correctly?
• Is the image contrast adjusted correctly?
• Are “Color” and “Tint” settings adjusted correctly?
• Is the lamp due for replacement?
When the lamp is nearly ready for replacement, the images become
darker and the color quality becomes poorer. When this happens, replace
the lamp.
• Do not match the CRT or LCD screen.
Computer monitors and LCD screens have different color reproduction
performance. So the colors projected by the projector and the colors
appearing on the monitor may not necessarily match, but this is not a sign
of a problem.
