I'm going to bump this topic again, since I have still not had much luck despite trying various things including SMBIOS changes. Does anyone know where I should go with this now?

I hate to have to bump this but I have been doing further research, it seems that the Gigabyte model has an issue where only two outputs (HDMI and 1x DP) work, @GertyMcGee describes an identical scenario to mine in this thread...

I have been going crazy since buying this GPU - I am unable to get it working correctly in Catalina or the Big Sur beta using OpenCore. It is very frustrating as there are so many reports of it working perfectly with both Catalina > 10.15.2 and the Big Sur beta, but I have also seen reports of...

I too am having that exact issue, and I've tried everything I can think of to solve it. FYI 10.15.x and 11.x do not solve it.

I tried MacPro7,1 and WG+agdpmod=pikera and still no luck... Edit: to clarify, I get no input detected on any display once the verbose boot is complete.

I installed the Big Sur beta but it doesn't fix the issue I'm having where my RX 5700 XT will not detect more than two displays. I've tried iMac19,1 and MacPro7,1 so far, and with the latter and no WG, I just get a black screen.

Thank you @LordHumungus, I have tried this to no avail. Back to original issue of primary monitor showing black screen, and all others disconnected. The NVRAM reset also hosed my EFI boot list, so I can no longer boot into Linux either. Looks like I have a long night ahead trying to recover...

After getting constant DumpGPURestart freezes with my Radeon VII and no solution in sight, I decided to sell it. I now have a Gigabyte RX 5700 XT, which I read was compatible with 10.15.6, however I am having no luck. I have read about a number of solutions on this forum and none of them have...

Here's the preview page on the Apple website, it doesn't seem to be linked publicly anywhere yet. It drops support for all remaining 2012 Macs. https://www.apple.com/macos/big-sur-preview/

Yes, some days I don't have problems. What clover version are you using?

I am encountering similar issues with my VII, where the system will freeze occasionally (though might be hours after turning on) and I have to force reboot. Occasionally the system will recover from the freeze after about a minute, sometimes two.

I used it previously with my 580, it seems to be a relatively new thing and only seemed to work with AMD cards. Absolutely 0 support for NVidia or Intel GPUs. Interesting, this would explain why it does not work. Thank you for that explanation. I'll not waste money on a DP hub either then, as...

I am using Radeon VII ---> DP to DP cable ---> Display ---> Active DP to VGA adapter ---> Extra monitor This setup works fine if I have only 4 displays connected, in this instance, using the 3 DP ports of the VII (including the Extra monitor above) If I plug a 5th display in to the HDMI, that...

I still have my old RX 580... but that might be a bit overkill (also I only have 750W PSU, would that be enough?) All 4 ports on my VII work fine, it's just if I connect more than 4 displays by means of daisychaining, things break (as described above). Do you believe that to be something I...

All of mine work too however I have more displays than ports, and daisy chaining seems to break things (it seems having >4 displays connected causes the one connected to the HDMI port to simply stop working) As I don't own another DisplayPort 1.2 compatible monitor nor do I own a DisplayPort...

Thank you. It does work, including QE/CI acceleration, however some applications have garbled text/images on all displays so I guess it it not fully compatible. Interestingly, the UHD630 and display does not appear at all in system report, however the connected monitor appears in the displays...

I just need to know the correct bootflags in case there is WhateverGreen interference, and the correct ig-platform-id to enable the GPU correctly. Would you happen to know this information? I had an RX 580 and the HD 4600 working in this way on my previous build which worked fine with multiple...

I have a specific reason for wanting to plug this display device into the IGP - the VII does not support >4 monitors on macOS, this includes when chaining DisplayPort outputs through my U2515H.

I'm wondering if anyone can help with this, I have a system where I would like to use my integrated GPU and my discrete GPU for powering dual monitors. Currently my integrated GPU has been configured as headless. I have an Intel UHD 630, and the rest of my specs can be seen in my profile...

Perhaps I should post here about this too; has anyone tested these? I am looking at StarTech's MST hubs.
