Omen Obelisk Desktop with 4 Monitors only freezes and no signal by watching videos

HP Recommended
Omen by Obelisk Desktop 875-1xxx / 32 GB ram / AMD Ryzen 7 3700 8-Core
Microsoft Windows 10 (64-bit)


I connected 4 Monitors (3 over Displayport and 1 over HDMI) on my brand new Omen Obelisk. All is working fine and without any errors. When I play than a video, sudently the mouse and tablet freeze, and some seconds later monitors loose signals and they are going to stand by mode - I have to push the power button to shut down the PC and than reboot the system so monitors are again connected.


It is very strange, that it happens only by watching videos, and even then, when nothing else is running than Win10. I let run the hp analyzing tools and every thing is ok. It never happens when no videos are running - PC runs without problems the hole week...


Can you please help me?
