I have an RX 480 running via HDMI 2.0 to my TCL P-series 4K TV. I have no problems if I run at 1080P, but whenever I run it at 4K, 60hz I have issues.
I tested it again last night while mucking around in World of Warcraft, Archeage and Divinity: Original Sin 2. I had set the resolution via my desktop to be at 4K, 60hz and the same as in-game and everything seemed to be working fine.
After some time (maybe an hour or so) I'd start getting the familiar "flickering". If left alone, it will continue getting worse during the session and may eventually completely go to a static screen.
Has there been found to be any resolution for this? Or is the RX 480 just incompatible with 4K gaming? I haven't seen any definitive solutions during all my googling for this issue.
