Problems with my Crossover 27Q

Hey guys, I recently received my Crossover 27Q but immediatly stumbled upon problems. I have a pc with a HD6870 Sapphire graphics card, this card has a dual link DVI-I and DVI-D port. I connected it to the dual link DVI-D port with the provided DVI-D cable since I read that these only work with DVI-D. I received no display. The DVI-I port worked, however the monitor was stuttering. I set it to different resolutions, updated the Catalyst drivers, nothing.

I thought I received a bad cable so I bought a new DVI-D dual link m/m cable but neither did that work.

Just to be sure, I took a picture of the ports:

The right one is the dual link dvi-d port right? This is the port that does not work. The left port works.


On this comparison pic it tells me I'm connected to the DVI-I port.


I also took a video, showing the stuttering it gives, took it with my crappy phonecam but what you don't see are flickering white pixels:

The seller explicitly said this monitor only works with DVI-D, but on my Sapphire the port does not work and I'm connected to the DVI-I. I believe this is the reason my screen stutters, how do I make the DVI-D port work?

Thanks in advance!
