but it seems to work fine through the RX 570 but no just a black screen via the RX 5700 XT. I included my Config file maybe someone can help me out! Would really appreciate it! Thank you!

Both GPU are connected. The Rx570 via HMDI and the Rx5700 XT via DisplayPort. The Rx570 shows under Pcie slot 2 in apples System Information being connected to my monitor. The Rx5700 XT is shown under Pcie slot 1 in System Information but not saying it’s connected to my display.

ok, I don't have any experience with dual graphics card like this, what happens if you just use the 5700, I am using a RX 5700 XT with two 27inch 4k Samsung monitors without issues,

I will unplug from the motherboard and see what happens. Can you upload your efi folder so I can compare? I will attach mine.

unplugged the RX 570 from motherboard and now no video output at all.
