If you installed a display adapter card, make sure your monitor and display adapter match. Also check to see if the card’s switches or jumpers and the jumpers on the system board are set properly. See Chapter 3 for system board jumper information.
If you are running an application program, see if you need to set up the program for the type of monitor and display adapter you have. Also make sure you are using the appropriate monitor and display adapter for your software.
Note
If your application program requires a monitor that supports graphics but you have a monochrome monitor, the results will be unpredictable.
The power switch is on but the power light is not on.Turn off the monitor’s power, wait five seconds, and turn it back on.
If the light still does not come on, check the electrical outlet for power. Turn off your monitor and unplug it from the outlet. Then plug a lamp into the wall outlet and turn it on. If the light turns on, your monitor may be faulty.
