Hello,
i have just acquired a Dell P2715Q and am using it with a Dell U2713HM on a new Mac Pro machine using Bootcamp and Windows 8.1 Pro 64bit.
The video card is dual AMD D700 with drivers for AMD 7900 series for the simple reason of having better API support.
I use DP to miniDP cables, one of them is the one that came with the P2715Q.
The problem:
Every time the computer goes to sleep or displays are turned off i get the DisplayPort Link Failure error
All the windows layout get messed up, moving everything to the main display.
I have to say that before this change i had 2 U2713HM and all worked just fine.
I am looking for any help that could help solve this issue.
Thanks in advance
