Hello @MaLd0n
It has also been impossible for me to create a patch with hackintool including the EDID in addition to other things. I think I'm going to give up because I've already tried everything I could find with no luck, I only get video through an external monitor, and it's a laptop, I need to get video through the internal lvds monitor but the screen always stays black .
Thank you very much for your help, I am sending you my donation for your DSDT.aml patch for sleep mode and other tips. I'm going back to Clover 5104 with Catalina 10.15.7 where I have full functionality, too bad graphics acceleration for HD 620 with OpenCore doesn't work in Big Sur 11.0.1,
regards
