    I recently purchased an xfx rx580 gts xxx 8gb gpu to replace r9 280. I am running windows 10 pro 64bit and have a ryzen 5 1600 in gigabyte ab350 gaming 3 mb. I have a thermaltake 80+ 600watt psu and a single stick of ballistix sport 8gb at 2933hz. After a few hours of gameplay the screen started flashing black repeatedly. I changed hdmi cable tried different ports and finally gave up after a few days and returned for a replacement. Installed replacement and it will only work in 1080p on an lg 50in 4k tv. If i change the resolution to anything higher it starts flashing and sometimes crashes to green screen. I am out of ideas other than taking to local tech to see if he can figure it out. If you need any more information I will post it. Thanks.

    Are you using a good quality high-speed HDMI cable? Older spec cables may not be handle the higher bandwidth, and crappy cables do cause problems too. It's a cheap place to start unless you know both your cables are quality High Speed cables. You don't need a super expensive gold plated 4k labelled flashy cable but it should be a decent quality cable that's advertised as High Speed. You can get a Monoprice 6ft HDMI for about $4.
