Comment (by rudolfc):
Thank you.
It turns out your 1680 display is not recognized by the driver: it does
not get the DDC/EDID info from it. The result is that a large part of the
gfx card is not programmed, resulting in the effects you see. It's no
fault of the monitor, as the BIOS -does- see it at system start.
The 1920 screen -is- detected by the driver, so apparantly the analog port
DDC channel is functional, but the digital(s) is(are) not.
- Can you post a few photo's from the 1920 screen with the artifacts you
see there so I can maybe get a bit better view on that as well?
- For the digital connection I will have to find a seperate solution. I
cannot help this at this moment as I first need to complete
modeprogramming as good as I can.
