OK, thanks for your help. I understand getting the acceleration on Intel Iris Plus is not a simple thing. I thought you might have a ready solution. That means you have another Intel UHD not Iris Plus and the other card does work correctly? What about getting the Nvidia MX230 running. Do you have it working on your system? Here our Nvidia cards are the same, could you please share your full EFI with me if possible?
Thanks for your help again.
PS. I messed things with my henrkk amount, lost my password and could not retrieve it so I created a new one henrkk1.
