Hi, I have a Gigabyte Radeon RX 580 Gaming, 8GB GDDR5, video card, conectted through HDMI to a Sony Bravia TV 49XE80077.
1) I get constant wattman errors - changing the values as written on forums didn't change anything.
2) Screen goes randomly black - changin cables, ports, resolution settings didn't affect anything.
3) I have some random dots/artifects on screen refresh in windows 10 and I don't know what may be the cause of all that.
I will post 10 seconds clips showing you my problem.
Edit: Seems that changin the wattman settings does improve the settings and screen does not go black that much. Still having problems with these errors you see in the videos.
