Symptom
Action
The monitor has screen jitter, or
the screen image is wavy,
unreadable, rolling, or
distorted.
1.
If the monitor self-tests show that the monitor is working correctly, consider
the location of the monitor. Magnetic fields around other devices (such as
transformers, appliances, fluorescents, and other monitors) can cause screen
jitter or wavy, unreadable, rolling, or distorted screen images. If this happens,
turn off the monitor.
Attention:
Moving a color monitor while it is turned on might cause screen
discoloration.
Move the device and the monitor at least 305 mm (12 in.) apart, and turn on
the monitor.
Notes:
a.
To prevent diskette drive read/write errors, make sure that the distance
between the monitor and any external diskette drive is at least 76 mm (3
in.).
b.
Non-IBM monitor cables might cause unpredictable problems.
2.
Reseat the monitor cable.
3.

restarting the server each time:
a.
