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 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 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 and text screens.

The test is complete when the white 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.
