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
and
Button 4
on the front panel
simultaneously for 2 seconds. A gray screen appears.
4.
Carefully inspect the screen for abnormalities.
5.
Press the
Button 4
on 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
screens.
The test is complete when the
Text
screen appears. To exit, press the
Button 4
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.
