Connecting TV via HDMI to RX580 Nitro

[freshynek]

I have KabyLake desktop MSI Z270 Gaming Pro with AMD RX 580 Nitro working well. My screen is connected via DP cable.  Now I want to connect my TV via HDMI cable. When I plug the HDMI into the graphics card, the Hack freezes instantly. I tried to connect the TV before turning the PC on, still a freeze. Find a link to my EFI:

Thank you for any help.

Thanks Daniel, the TV over HDMI now works fine! But with MacBookPro14,1 SMBIOS I loose Power Management. Maybe it was never working before. I got the dsdt.aml from you with iMacPro1,1 SMBIOS but for the Native Power Management I guess I need the iMac17 or iMac18 SMBIOS. How can I manage the native Power management. When I turn the PC to Sleep it does not wake up, I need to restart.
Thank you.
