SOLVED DisplayPort not working for RX 580 in Sequoia.

Hello,

Currently, none of the two DisplayPorts are working on my RX 580.

Here are my spces...
AMD Ryzen 9 3900X CPU
ASRock AM4 A520M-HDV Micro ATX Motherboard
Sapphire Nitro+ RX 580 GPU
Kingston Fury Beast RGB 64GB DDR4-3600 RAM
Western Digital WD_Black SN850X 2TB SSD
Fenvi FV-T919 Adapter

Attached is my current config.plist

Any help would be appreciated. Thanks!

Your system shouldn't require CryptexFixup.

Ensure that the CSM is turned off in BIOS and 4G Decoding is Enabled. When you enable 4G Decoding, remove the npci flag. Also, it would be nice if you can check if the NVRAM is working under macOS.

Also, you should consider removing brcmfx-driver=2 agdpmod=pikera from boot args.

Are HDMI ports functioning well?

So I removed CryptexFixup and made sure that CSM is disabled and 4G Decoding is Enabled. I also removed brcmfx-driver=2 agdpmod=pikera from boot args. The only thing I didn't do just yet is remove the npci flag. Should I remove it completely from the boot args in my configurator? I'm using OCAT.

Also, my HDMI ports are working fine and my NVRAM seems to be as well.
