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 are set properly. If your display adapter
card is not VGA, make sure you have your service
representative disable the system’s built-in VGA adapter for
you.
If you are using a monochrome monitor that is not VGA
compatible, make sure you change jumper 6 on the system
board to position 2-3 (see Chapter 2) and select
MONO
for the
Video
Card
option in SETUP (see Chapter 1).
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 non-VGA 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.
