Description

Jittering, unreadable, rolling or twisted image is displayed on the monitor screen. 

Solution

To solve the problem, proceed as follows:

1. If monitor self-test indicates that the monitor works normally, consider the position of the 

monitor. The magnetic field around other devices (such as transformers, electronic 
devices, fluorescent lights, and other monitors) may cause screen jitters, image 
fluctuation, or unreadable, rolling or twisted image.

2. Close the monitor if this condition happened. When you move a color monitor, the color of 

the screen may be distorted. Move the device and monitor. Make sure that the distance 
between them is at least 305 mm.

3. Turn on the monitor. If the problem persists, replace the monitor or ATCA-7150. For details 

on how to replace the monitor, refer to the document shipped with the monitor that you 
use.
