I'm having abit of a issue with my new TV - Not sure if its a setting or compatibility issue. I have a UE55MU7000 Tv and using it as a PC Monitor. I am running windows 10 and my GPU is a Palit GTX 970 which I beleive suppport 4k.
Now as soon as I turn on HDMI UHD Colour for my HDMI 1 input the screen goes black and flickers. I'm not sure what the issue is. Once I turn it off its fine and I am able to use the native resolution 3840x2160 however limited output format of ycbcr420 - 8bit.
