So, I just bought a new 144hz 1440p Monitor. Before I was using 2 1080p @60Hz Monitors and everything worked fine, but after connecting the new monitor I noticed that when gaming the screen turns black for a few seconds and then comes back. Everytime this happens it says "DP" in the upper right corner like the monitor was reconnected. I also see some random artifacts that go across the screen from time to time. The cbales arent the problem and neither is the monitor itself, because I tested with my old GTX 950 and it worked fine.
Specs: XFX RX 580, Ryzen 7 2700x, G.Skill aegis 16gb ddr4, samsung evo 970 m.2, asus x470 pro, corsair 650w psu, win 10
I already tried reinstalling latest and some older AMD drivers, disconnecting the 2. Monitor, setting HZ to 120/60, resolution to 1080p, undervolting. Another thing I noticed was that the GPU runs at 50°C on idle with fans randomly revving up and under load it can reach 85°C at 144hz and 75° at 120hz. Any help is aprreciated.
