xSeries 445 Type 8870: Hardware Maintenance Manual and Troubleshooting Guide
Monitor problems
FRU/action
1. If the monitor self-tests show the monitor is working properly, 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 on the monitor.
Notes:
a. To prevent diskette drive read/write errors, be sure the distance between
monitors and diskette drives is at least 76 mm (3 in.).
b. Non-IBM monitor cables might cause unpredictable problems.
c. An enhanced monitor cable with additional shielding is available for the
9521 and 9527 monitors. For information about the enhanced monitor
cable, contact your IBM reseller or IBM marketing representative.
