3.If the monitor’s power light still does not come on, check the electrical outlet for power. Turn off your monitor and unplug it from the wall outlet. Plug a lamp into the wall outlet and turn it on to see if the outlet supplies power.
4.If you still do not see anything on the screen, make sure your monitor is connected to the computer properly. See “Connecting the Monitor” in Chapter 1 for more details. Also check the monitor manual for instructions on how to connect it to the computer.
5.Make sure your monitor and display adapter card match, and, if your display adapter card has any switches or jumpers, be sure they are set properly. See “Connecting a Monitor” in Chapter 1 and the documentation that came with your monitor and display adapter card for instructions.
6.If you are running an application program, see if you need to set up the program for the type of monitor and display adapter card you have. Also make sure you are using the appropriate monitor and display adapter card 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.
7. Be sure you have chosen the correct display adapter card type in the Setup program. See “Setting the Display Adapter Card Type” in Chapter 2.
8.If you are still having difficulty with your monitor, try running either the Monochrome Display Adapter and CRT Check or the Color Graphics Display Adapter and CRT Check, as described in Appendix C. If the diagnostics program indicates an error, contact the place where you bought the monitor.
