Wavy, unreadable, rolling,
distorted, or jittery screen
images. If the monitor self-tests show that the monitor is
working properly, verify that:
1. The location of the monitor is appropriate.
Magnetic fields around other devices, such
as transformers, appliances, fluorescent
lights, and other monitors might be causing
the problem. To determine if the location is
causing the problem:
a. Turn off the monitor. (Moving a color
monitor while it is turned on might cause
screen discoloration.)
b. Adjust the placement of the monitor and
other devices so that they are at least 305
mm (12 in.) apart. Also, when relocating
the monitor, be sure it is at least 76 mm (3
in.) from the diskette drives to prevent
diskette drive read/write errors.
c. Turn on the monitor.
2. A monitor signal cable is properly
connected to the monitor and computer, and
that the cable is installed securely.
3. You are not trying to run your monitor at a
higher refresh rate than the monitor
supports. See the documentation supplied
with your monitor for supported refresh
rates.
Note: An enhanced monitor signal cable with
additional shielding might be available for
your monitor. See your IBM reseller or
marketing representative for information.
If this does not correct the problem, contact IBM
technical support.
