Hello, I wanted to install Sequoia. But somehow I think my graphics card is causing problems. There are always some mosaic points. I did the complete installation with Opencore and created all Kex etc.. Would be nice if someone could take a look at my Efi. Thank you

Your system shouldn't require the following:
ResetLogoStatus
FixupAppleEfiImages
CustomSMBIOSGuid
UpdateSMBIOSMode (Custom)

Also, ensure that your kexts are up to date. If the issue is not fixed, check your BIOS settings and ensure your display cable is not faulty.
 
My screen cable is not defective, when I start windows a picture comes up, my texts are up to date, I try to delete the unnecessary and try again.

Could you share the video describing the issue? It might be possible that the system memory has problems or the GPU is faulty itself.
 
I'll make a video and post it here

Seems like there was a misunderstanding. Provide the current settings of your BIOS>Advanced>IO Ports section
 
Here its photo from IOPorts

Is there a complete guide (not Opencore long way guide) to making SSDT's from my DSDT and not using SSDTTIME.
