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 Is my card messed up, is it the monitor, is it the card drivers? Has anyone had this issue? I have been trouble-shooting and can't figure it out.
