Troubleshooting
If your monitor fails to operate functionally, it may be possible to
correct the problem by making simple checks as follows:
Refer to the operating instructions for your computer/video
adapter to ensure that you have the correct signal output source
for the monitor. Ensure that the video adapter is set correctly for
operation with this monitor.
If the above steps fail to correct the problem contact your
Compaq service provider.
* NOTE: You can easily distinguish if the problem is on the
monitor or on the computer by using the monitor’s built-in
selftest function. With the monitor power ON, disconnect the
signal cable from the monitor. If you see a “CHECK SIGNAL”
image on the screen, the monitor is functioning properly, and the
problem is with the computer or signal cable.
