I just built a new Ryzen system a couple weeks ago and I put a Radeon RX 580 in it. My complete specs are in my sig. I also got a brand new monitor a couple days ago. I was really wanting to use the DisplayPort but whenever I try to play a game, the DP stops working and my screen goes black. Here's a run-down:
- everything works fine when I use the HDMI cable but it seems my screen is locked at 60MHz
- with the DP, my monitor will run at 144MHz (its native refresh rate) but goes black during games
- with the DP, I have no issues while in Windows doing mundane stuff and I can even launch games and be in the game menus with no issues; the screen only goes black once I am actually playing
