Troubleshooting
Monitor Problems
Action
Wavy, unreadable,
rolling, distorted screen,
or screen jitter.
If the monitor self-tests show the monitor is OK,
consider the location of the monitor. Magnetic fields
around other devices (such as transformers, appliances,
fluorescent lights, and other monitors) can cause screen
jitter or wavy, unreadable, rolling, or distorted screen
images. If this happens, turn off the monitor. (Moving
a color monitor while it is turned on might cause
screen discoloration.) Then move the device and the
monitor at least 305 mm (12 in.) apart. Turn the
monitor on.
Note:
1. The distance between monitors and diskette
drives should be at least 76 mm (3 in.) to
prevent diskette drive read/write errors.
2. Non-IBM monitor cables might cause
unpredictable problems.
3. An enhanced monitor cable with additional
shielding is available for the 9521 and 9527
monitors. See your IBM reseller or IBM
marketing representative for information
about the enhanced monitor cable.
If the problem recurs, have the monitor and system
serviced.
Screen flickers.
Set the monitor for the highest, noninterlaced refresh
rate available.
To reset the refresh rate, use a utility program, such as
AnyView Professional or WinMode.
The monitor works when
you turn on the system,
but goes blank when you
start some application
programs.
Verify that the primary monitor cable is connected to
the video port.
To find the video port, see “Input/Output Connectors”
on page 9.
Be sure you installed the necessary drivers for the
applications.
