question, I got the same laptop as you 7559 4k screen I patched the dsdt and everything seems like its working fine except graphics acceleration, can you please tell me how did you get your graphics working? I can only boot with ig-platform set to 0x0a260006, thank you very much
Using an invalid ig-platform-id will simply disable the graphics drivers.
Did you use the pixel clock patch (IOKit/CoreDisplay patch) for 4k?
