Hi, it seems that my r9 290 will not work as diplay port 1.2 in 4k (60hz) even though it says it supports this feature. I have the catalyst 14.6 beta driver installed on windows 8.1 64 bit. Im using the new AOC U2868PQU monitor and have made sure that the monitor is in DP 1.2 mode. it works fine in 30Hz mode other than it being yahno, 30Hz.
Any help you can offer is greatly appreciated.
