Intel Arc A770m powers off monitor by itself / HDCP?

[Zernichthor]

I got a Intel NUC 12 Enthusiast with a Intel A770m grafic chip. I am using 2 monitors, one is connected to the Display Port, the other to HDMI. 

Its very frustrating, everytime I start a rallytv stream the second monitor on HDMI turns off. The whole windows setup changes to a 1 monitor setup. The only way to get it working again is by unpluging the HDMI cable and repluging it. Nothing else works. I use new HDMI 2.1 and DisplayPort 1.4 cables.

My guess is it has something to do with HDCP maybe? I had the same 2 monitors with my Nvidia 1050ti graficscard on my previous PC and never had this problem. 

Is there any solution to this? is that a common problem with the A770m? Because this is a NUC device I dont believe I am the only one with this problem.

Drivers Installed:  31.0.101.4826 (latest at time of writing)

NUC Bios: 0058 (latest at time of writing)

Monitor 1: DP 1440p 120hz (variable refreshrate disabled), DP 1.4 cable on DP 2.0 port

Monitor 2: HDMI 1440p 75hz (no variable refreshrate supported), HDMI 2.1 cable on HDMI 2.1 port

Thanks for the help.

Thanks, the only solution I found was connecting both screens with DisplayPort. So the problem seems only when mixing one screen on hdmi and one on DisplayPort. It was never a Problem with Nvidia tho. I dont like using DisplayPort on Multiscreen setups because its so bad, but for now i accept this fate, so the problem can be marked as solved. Thanks for the help.
