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.
To run the built-in diagnostics:
1.
Ensure that the screen is clean (no dust particles on the surface of the
screen).
2.
Press and hold
Button 5
for four seconds until a pop menu appears.
3.
Using the joystick control, highlight the
Diagnostics
option and press the
joystick button to start the diagnostics. A gray test pattern appears at the
beginning of the diagnostic program.
4.
Observe if the screen has any defects or abnormalities.
5.
Move the joystick to the right until a red screen is displayed.
6.
Observe if the screen has any defects or abnormalities.
7.
Repeat steps 5 and 6 until the screen displays green, blue, black, and white
colors. Note any abnormalities or defects.
The test is complete when a text screen is displayed. To exit, move the joystick to
the right 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.
