Catalina - Asus Z390-A + Gigabyte RX 5600 XT - Dual Display and Hardware Acceleration

[Gen.MIDI]

I'm a total noob - not at building PC's but in the Hackintosh world.

Quick hardware rundown and then I'll get to the graphics related issues.

Motherboard: ASUS Prime Z390-A HDMI, SATA III, USB 3.1 ATX Motherboard
Processor: Intel i7-9700K Coffee Lake w/UHD Graphics 630 Processor (BX80684I79700K)
Graphics: Gigabyte RX 5600 XT
Samsung NVMe 500Gb SSD for Mac OS only - has a separate SAMSUNG 860 EVO Series for Windows

Because he had the same motherboard and honesty it was superbly written, I followed the guide by pjowio here: https://www.tonymacx86.com/threads/...pulse-asus-thunderboltex-3-working-tb.300721/

Our graphics cards are different and perhaps that is my problem.

I'm up and running in the latest Catalina but I have two issues.
1. Dual Screen, it will only display on the HDMI output. Second monitor hooked up to the a display port is blank and not recognized by the OS.
2. Video Hardware acceleration - Shown as unavailable in several apps.

Please understand that most of this stuff is still Greek to me but I'm learning. I appreciate your help in advance.

Thanks. I had seen the 131 page thread and got lost a couple pages in. I'll take another look.
