Personal Computer User Manual

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.

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

your application

program requires

a monitor that

supports graphics but you have a monochrome monitor,

the

results

will be unpredictable.

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.

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.
