EDID may be different for different screen. this is mine:
Please add it to DeviceProperties/Add/PciRoot(0x0)/Pci(0x2,0x0) like this:
Create a new entry: AAPL00,override-no-connect (with type data)
And set the value to:
00FFFFFFFFFFFF004C834FC30000000000190104A52213780AC585A3574F9C2612505400000001010101010101010101010101010101A6A600A0F07019803020260058C21000001AD8CC00E0F17071813020260058C21000001A000000FE0044574A305280313536464C0A2000000000000241219B610000002B010A2020004D
