Built-in diagnostics
Your monitor has a built-in 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 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 Exit button (button 4) for four seconds to enter the OSD

lock/unlock menu.
