I have just purchased the above monitor and I'm currently trying to set it up. I want to use it with displayport cables rather than HDMI cables so that I can have 3 of these monitors set up all using DP. Unfortunately at the moment I can't get it to work with DP at all - it produces a blank screen every time and when I have another monitor plugged in with HDMI I can see that it isn't being detected properly by Windows or Ubuntu. I've tried installing the drivers, navigating to the monitor-menu to enable DisplayPort 1.2, and power cycling all with no effect.
I don't understand why it works perfectly with HDMI but as soon as I try to switch over to DP it funks out.
Any help would really be appreciated. Cannot get my head around why this appears to be so complicated in the least!
