I have the AMD Radeon Pro Vega II, 16 Core, and three displays.
Two are Slate Raven (HD) MTi2, manufactured Nov 2019.
One is a Samsung 4K QLED 43"

If all displays are connected to the VEGA II
HD1 is HDMI to USB-C
HD2 is HDMI to HDMI (This display Won't Work)
4K is HDMI to USB-C
1 TB3 to TB2 to external Soundcard


Connect them all via HDMI to
USB-C cable - All Work
HD1 is HDMI to USB-C (TB3 port from Apple I/O Card on Back)
HD2 is HDMI to USB-C to Vega II
4K is HDMI to USB-C to Vega II
1 TB3 to TB2 to external Soundcard

Did you open the link I posted? It's pretty self-explanatory.
I don’t know how I missed the link, but I did have one HDMI to HDMI to the HD display, and one running to the 4K display, side-by-side and it says it supports that. Also, the machine I had before the 580x Was having issues with HDMI as well. was having issues with HDMI as well. I’m wondering if this is some kind of driver issue with AMD.
