Displayport 1.2 Cable source in GTA

[claytonno]

As the title suggests I am looking for a place to buy a displayport 1.2 cable as I purchased the samsung 4k U28D590D second hand and he did not include the original displayport cable that shipped with the monitor. I would like to get it running at 4k 60hz(I know it works because I have gotten it to work in picture by picture mode with dual cables and eyefinity enabled with significant frame pacing issues in games and when I restart my computer the display won't work in this mode unless I unplug one cable and plug it in and reconfigure eyefinity). I ordered a cable from monoprice for $9 but I heard shipping to Toronto can be weeks. I just built a brand new $3000 watercooled rig I am pretty anxious to get it running at 4k 60hz. Any help would be greatly appreciated

There were no changes to the cable spec from 1.1 to 1.2, so any DP cable is a DP 1.2 cable.

Thank you so much for the reply, I think there may be a driver issue with crossfire 290x and 4k output right now as I can only get it to work via dual cables and picture by picture mode, I thought it was the cable but i am pretty sure you are correct, hopefully amd fixes this soon.
