You might need to set DVMT https://osxlatitude.com/forums/topic/13963-changing-dvmt-values-in-bios/

Not sure if you looked at your IOReg file, but your SMBIos shows Optiplex 3070 instead of iMac19,1 you try to emulate. Don't know if that could be the issue but it's worth looking into. Looking at your config file, I see you have UpdateSMBIOSMode set to custom which is fine, but you need CustomSMBIOSGuid enabled as well. They both must be paired correctly. You currently have it disabled. If you want it disabled, then you'll need to set UpdateSMBIOSMode to create. Go with the 1st option. Fix that and see if it makes a difference and we'll go from there.

Can you post IOReg file with the AMD card?

Honestly I have never done it from Windows but looking at the Dortania guide, that looks correct.

post IOReg file for each display detected

added the AGDP patch as suggested by Hervé Archive2.zip

@heysahilsingh try this patch, see if it'll help https://osxlatitude.com/forums/topic/8723-enabling-dvidphdmi-and-increasing-vram-with-intel-haswell4th-gen-hd420044004600etc-igpu/?do=findComment&comment=84623 R7 240 can work by spoofing See here https://dortania.github.io/Getting-Started-With-ACPI/Universal/spoof.html So to spoof the GPU, we need to find a couple things: Suitable PCI ID for the GPU ACPI Path of the GPU SSDT-GPU-SPOOF.aml

VGA port is either supported natively or it does not. It varies from system to system. In your cast, I assume it's not.

Looks like you put the EFI folder in the same location as com.apple.recovery.boot

https://dortania.github.io/OpenCore-Install-Guide/installer-guide/winblows-install.html#downloading-macos or use some 3rd party app to mount your EFI partition

follow installation guide here but use the EFI you have downloaded https://dortania.github.io/OpenCore-Install-Guide/ https://dortania.github.io/OpenCore-Install-Guide/installer-guide/mac-install.html#downloading-macos-modern-os

Did you download MacOS and create the installer using createinsteallmedia command? Then mount the EFI partition to add the EFI folder? Sounds like you only have an EFI folder boot without the installer
