hi! I am looking for help for my Hackintosh GPU problem. I have been hackintoshing for some years now (since OSX Maverick). Usually I managed to solve most problems even by hacking GPU drivers. But my attempt to upgrade to Monterey has failed. I have a system based on: mobo GA-990XA-UD3 (UEFI), CPU FX-6300, Mem 8GB, GPU NITRO+ AMD Radeon RX590 8GB, 1TB SSD with Monterey and 120GB SSD with Big Sur. Big Sur works just fine. Monterey works only without GPU acceleration (NVRAM > boot-args = -amd_no_dgpu_accel). If I enable GPU acceleration in OpenCore (remove the -amd_no_dgpu_accel argument) then after the accelerated Apple logo during boot the screen goes black. Any ideas?

Hello Guest. Before you post check the Troubleshooting guide here, Dortania Troubleshooting
I mean physically record with your phone. There may be a message of use that shows while this is happening which we can see if we slow playback / look frame by frame.
Good evening! I did what you said and I am posting 2 videos from (failed) Monterey boot attempt. In the 2nd video near the end there are some messages, but I don't think they are relevant to the problem (failure to land the Login Screen).
Neither of the two videos is very helpful.
The first video is too out of focus/blurred to allow anyone to read the Verbose Text. You need to set the phone camera so it is held steady and focused on the verbose text, then shoot the video to show the whole screen in focus.
The second video is showing nothing hack related, rather it is showing a hardware issue between your GPU and Samsung screen.
I assume you are using a DisplayPort to connect the GPU and Samsung screen.
Are you using a DP to DP cable to connect the GPU and screen?
Are you using any adapters or cable adapters or anything else to connect the GPU and screen?
Is the cable fully seated in the GPU and screen DisplayPort connectors?
Is the cable in good condition, i.e. no kinks or sharp bends in the cable?
Is there any damage to the connectors at either end of the cable?
How many drives do you have connected to this system. When troubleshooting issues on a Hack it is best to remove any non macOS drives, e.g. backups, data or other OS drives. All. that should be connected is your macOS drive and the USB drive you are using to boot the system. These other drives can be reconnected once you have macOS Monterey booting to the desktop on a regular basis.

The 1st video shows just the messages of the display. A message aknowledging the pressence of Display Port and the bottom messages are the screen's messages regarding display characteristics and controls. Have nothing to do with the system GPU init process. The GPU and Display are connected with DP to DP cable and work fine on Big Sur installation.
