Troubleshooting Troubleshooting Procedures
This LCD monitor comes pre-adjusted with standard VGA timing. Due to
output timing differences among various VGA cards, you may initially
experience an unstable or unclear display when a new display mode or new
VGA card is selected.
Before applying any of the following troubleshooting procedures, you should
first apply the Auto Adjust option in the OSD menu.

Control buttons until horizontal dark and light lines appear. The

you have a clear display.
