Onboard diagnostics
Your monitor has a onboard diagnostic tool that helps you determine if any screen abnormality you experience is an inherent problem with
your monitor, or with your computer and video card.
NOTE: You can run the onboard diagnostics only when the video cable is unplugged and the monitor is in self-test mode.
To run the onboard diagnostics:
1.
Ensure that the screen is clean (no dust particles on the surface of the screen).
2. Unplug the video cables from the back of the computer or monitor. The monitor then goes into the self-test mode.
3. Press and hold the Exit button (button 4) for four seconds to enter the OSD lock/unlock menu.
4. Select the
icon to run the onboard diagnostics.
5. Carefully inspect the screen for abnormalities.
6. Press the Up button (button 1) on the back cover again. The color of the screen changes to gray.
7.
Inspect the display for any abnormalities.
8. Repeat steps 6 and 7 to inspect the display in red, green, blue, black, white, and text pattern screens.
The test is completed when the text pattern screen appears. To exit, press the Up button (button 1) again.
If you do not detect any screen abnormalities upon using the onboard diagnostic tool, the monitor is functioning properly. Check the video
card and computer.
