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 and Button 4 on the front panel simultaneously for 2

seconds. A gray screen appears.

4 Care

fully inspect the screen for abnormalities.

5 Press Button 4 on the front panel 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 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.
