Troubleshooting
Problem description
The previous image remains
slightly visible on the screen
On a dual-head system, the
images on the left and right dis-
play seem to be switched
Note: What if the graphic board resolution is too low
Some non-Barco graphic boards (e.g., single-link boards) may
have an insufficiant resolution to drive the display. You can solve
this problem by forcing the graphic board to operate on a lower
vertical frequency. Therefore, proceed as follows:
1. Shut down the PC.
2. In the display OSD, browse to the Settings menu.
3. Select the function Preferred Input Freq.
4. Select 45 Hz as vertical frequency.
5. Exit the OSD.

Possible tests or solutions
•
This phenomenon, called
"image sticking" is normal if
the same image has been on
the screen for a long time.
The ghost image will
disappear after some time.
Over 10 hours operation with
the same image content is
not recommended. Switching
on DPMS on display and PC
and activating a good screen
saver may decrease the risk
of image sticking (image
retention).
•
A slight case of image sticking
can be solved by continuously
displaying a full white image
during a number of hours.
•
Switch the video cables at the
display controller or at the
display video inputs
