Can't get above 85HZ with Radeon R290

Just got the monitor from NewEgg today. CCC displays all refresh options but choosing anything above 85HZ causes the display to lose signal and go blank. Running Win 8.1 64 bit and AMD driver 14.10.1006 (most current). Have reseated all cables, rebooted, power cycled monitor, etc. but it is unstable above 85HZ.

Had the same problem with my 1st one. Got it RMA'ed and then i could do 120Hz on another. 144Hz is not possible with AMD.

But i ended up having same problems as you on the 2nd aswell. It turned on/off every 2-5 mins.

Sell your AMD card and get nVidia instead - then everything works.... or return the monitor.. its not made for AMD apparently. Maybe down the line AMD will make driver support for it - but my life was to short to wait for that so i swapped GPU instead.
