Built-in Diagnostics
Your monitor has a built-in diagnostic tool that helps you determine if the screen
abnormality you are experiencing is an inherent problem with your monitor, or with your
computer and video card.
NOTE:
You can run the built-in diagnostics only when the video cable is unplugged
and the monitor is in self-test mode.
To run the built-in diagnostics:
1 .
Ensure that the screen is clean (no dust particles on the surface of the screen).
2 .
Unplug the video cable(s) from the back of the computer or monitor. The
monitor then goes into the self-test mode.
3 .
Press and hold the
Button 1
on the front panel simultaneously for 2 seconds. A
gray screen appears.
4 .
Carefully inspect the screen for abnormalities.
5 .
Press the
Button 1
at the front panel again. The color of the screen changes to
red.
6 .
Inspect the display for any abnormalities.
7 .
Repeat steps 5 and 6 to inspect the display in green, blue, black, white and text
screens.
The test is complete when the Text screen appears. To exit, press the
Button 1
again.
If you do not detect any screen abnormalities upon using the built-in diagnostic tool,
the monitor is functioning properly. Check the video card and computer.
