Hi there, I have an alienware with 2 radeon m6900 in crossfire mode. today my 27" screen arrived:
However it does not get recognized. I have it connected via dual dvi-d (monitor) to minidisplayport on the alienware via an adapter. The screen has electricity bc blue light is blinking but it stays black no matter what i do. i recently used a 26" over the same ports which was working just fine.
If i open catalyst control center i can see even see the screen which says "DUAL LINK DVI disabled" next to my laptop and 22"benq but it is impossible to extend or duplicate the desktop to the 27" . it just stays black. Tried alot of things now, quite sure my graphiccard and the screen are fine so it has to be something else which i'm missing. help is highly appreciated. if there are more questions please shoot, thanks
