Tested on RTX 3050 & Z390 ITX & i7 8600 = HLG & HDR & DV All Working
The only issue I have is that I need to use the DisplayPort on the graphics card to connect to an AV receiver, so that the audio can be processed separately from the display. However, it seems that the system turn off all other ports whenever a display is connected via HDMI—even the HDMI ports on the Intel motherboard stop working.
Direct connect to AVR not good for me limit 4K@30 not @50 or 60
