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 Ensur
e that the screen is clean (no dust particles on the surface of the screen).
2 Unp
lug 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 Button 1 for 5 seconds. A gray screen appears.
4 Care
fully inspect the screen for abnormalities.
5 Pr
ess Button 1 again. The color of the screen changes to red.
6 Inspect the display for any abnormalities.
7 Repeat ste
ps 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 Button 1 again.
If you do not detect any screen abnormalities upon us
ing the built-in diagnostic tool, the
monitor is functioning properly. Check the video card and computer.
