MSI GS73VR 17" 4k Display black screen on boot

[iamsanoj]

Hello,

My MSI GS73VR with a 17-inch 4K display only works with an external monitor over USB c with full graphics acceleration in opencore. I have googled a lot and found that the EDID has to be patched with 48Hz for Big Sur to boot with a 4K panel at the moment. I have tried editing EDID using CRU in windows but couldn't get it working. Tried with Linux as well using a python script(Link), There were some errors that I am not able to fix. I don't have such expertise to troubleshoot the python codes. The EDID I have extracted using Catalina in hackintool and DarwinDumb are attached. Need help in editing EDID.
