@MaLd0n I managed to get sidecar displayed by changing smbios to imac19,1 but it is very blurry and laggy which renders it unusable? What can i tweak to get it smoothy? I've changed shikigva to 80 but with no luck. Did i miss something? What's the difference betweeen "Datahub - generic -Platform nvram and "smbios" under Platforminfo of opencore configurator. I've edited Platfomr nvram but not edited smbios. Did that make a difference? But i do changed my model to imac 19,1. I am confused. Thank you!

@MaLd0n I've done that according to general framebuffer patch guide. But it doesn't work. When I connect dp and hdmi simultaneously, only dp work. When I connect hdmi first and connect dp next, I got both working. It's really weird. I think I didn't configure it correctly. Can you help me to find out way. hdmi is using index 1 and dp is using index 2.

@MaLd0n hi MaLd0n! I am using your Big Sur olarila image to install macOS to my Asrock Z490taichi motherborad. It installed perfectly and Everything is working fine except I can't use sidecar and airplay to Apple TV. I have a rx560 graphics card and I want to use Intel igup in headless mode. Could you patch that for me? Thank you! liubo’s Mac Pro.zip
