Using DP, and the only time my monitor goes off is after kernel has booted and the window server has started. It goes off for about 1-2 seconds and then it comes back. Same whether I use hdmi or DP. I’m using DP since my monitors are high resolution and very high refresh rate.
I have 3 monitors- LG4K (DP), LG4K UltraFine (TB3) and Acer HD (HDMI). The DP monitor activates first and gets through verbose, then deactivates at least once. Then the other two monitors activate, but remain black until the login screen. Sometimes the DP monitor shuts off twice. Once I'm past the login screen, no problems whatsoever. Never had this problem with RVII. Not that big a deal, just annoying.

the worst part about screens turning on and off is they get assigned new guids each time and sometimes macOS can't idenity what monitor is supposed to get one desktop background, so they revert to default. It's a pretty consistent bug that both real macs and hacks have when using 2 or more displays :\

Just received a nice new reference RX 6900 XT and it's running great so far. One thing I noticed, is that when moving the mouse pointer over a link, and it changes, the position of the pointer jumps momentarily then returns to the correct location. Had this on my previous XFX 5700. Just the IGPU does not do this. Any suggestions?
Thanks.

Here is a video of the problem.

Sry if this has already been talked about, but have there been any efforts to make the USB-C ports usable beyond just video/audio?

If not, what do we need to get them working as regular usb hubs?

I've been playing with my new graphics card for a few days now. Is a Asus TUF RX 6800 XT.
Is working well overall, I only have one issue for the moment:
If I want to use IGPU alongside DGPU I have to disable IGPU in bios during installation because I can't reach the installer. I can boot from opencore, I see verbose and immediately after verbose signal cut. If I disabled igpu, installation is working well.
After I have finished the installation I can activate IGPU and is working well.
My monitor is a 4K LG and is connected via DP.

Hi.
For those who have newest 6900 XT cards with XTXH chips. Please try latest WEG from master. Now it can spoof AMD device-id.
Three things you need:
1. Latest WhateverGreen.kext build from master
2. DeviceProperties fix (use Gfxutil)
3. SSDT-BRG0 table with correct path (without it device-id from DeviceProperties will not be injected)

If everything is correct your card should work without SSDT's, FakePCIID's etc.

That'll be nice to get rid of extra stuff, but will probably need more laymens directions then that as I don't have any idea what to do with SSDT-BRG0 or GfxUtil. put some instructions on it and i'll test it over all the hacky FakePCIID stuff

Can confirm, this works like a charm!
No further need for FakePCIID shenanigans.
