Question Monitor turns black for a few seconds

Feb 17, 2019
So I just got a new Monitor (MSI MAG27CQ, 144hz 1440p) and connected it to my rx 580 via Displayport.I also have a second monitor connected to the same GPU at 1080p @60hz. The problem is that the monitor turns black for a few seconds and then works again when playing games. This only happens when gaming and not when browsing for example. Everytime this happens i see a little box in the top left sayixnxg "DP" like the monitor lost connection and reconnects to Dsipalyport. This happens on any game: Apex Legends, Devil May Cry 5 and even Pummel Party. Im playing these games at 1440p @144hz. Im using the bundled DP cable, but I also tried an amazon basics DP cable I had lying around and the issue persists. I also noticed that the monitor doesnt automatically turn on when I start the PC, but i dont know if this is related somehow. Any help is aprreciated.
