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.
6. Reboot the computer.
After reboot, the signal from the graphic board should now
be visible on the display.
On a dual-head system,
the images on the left
and right display seem to
be switched • Switch the video cables at the
display controller or at the display
video inputs
