I bought three of these screens intending to daisychain them from my XFX HD 6670, which supports DP 1.2.
I have found that the displayport input simply doesn't work on any of them. I have tried the cables that came with the monitor, and another cable I know works as I was using it with my old U2410, which works perfectly on my system with dp.
I love the thin bezels and don't want to return the screens, but unless I can get them to work with dp I will have no choice! Can anyone suggest a solution?
