Screen goes blank when you start some application programs
1. Make sure that:
• The application program is not setting a display mode that is higher than the capability of the monitor.
• You installed the necessary device drivers for the application.
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-Lenovo monitor cables might cause unpredictable problems.
2. Reseat the monitor cable.
3. Replace the components listed in step 2 one at a time, in the order shown, restarting the server each
time:
a. Monitor cable
b. Video adapter (if one is installed)
c. Monitor
d. (Trained technicians only) System board.
