Built-in diagnostics

Your monitor has a built-in diagnostic tool. It helps you determine if the screen
abnormality that you are experiencing is an inherent problem with your monitor or
with your computer and video card.
To run the built-in diagnostics:
1. Ensure that the screen is clean (no dust particles on the surface of the
screen).
2. Press the Joystick button to launch the OSD Main Menu.
3. Move the joystick button to select Others > Self-Diagnostic to initiate the
self-diagnostic process.
4. When initiated, a gray screen appears. Inspect the screen for abnormalities.
5. Switch the joystick button. The color of the screen changes to red. Inspect
the screen for abnormalities.
6. Repeat step 5 and inspect the screen when it displays the colors green, blue,
black and white followed by the on-screen text.
