Hi everyone, ive got a quick question, ive got PC connected to my monitor via DisplayPort, today ive connected xbox x via hdmi 2.1, and everything is working great, but... if i change source to DP, and im working on my PC (xbox is turned off), every 10-30-60 sec (random) my monitor tried change source but is like a reload displayport, black screen and for 3 sec, and my PC is back to live, ive got just info about DisplayPort and resolution, after another 30 sec, same... is really mental, but when hdmi cable from my xbox is taken off, problem dissapear...any ideas?
