Myp3a Posted June 19, 2020 Share Posted June 19, 2020 (edited) I have a Samsung NP900-X3C. Anything I would try, internal display doesn't work correctly. CPU: i7-3517U Chipset: HM75 Mobile GPU: HD4000 (Only one) Display: LVDS, 1600x900 GPU ACPI Path: _SB0.PCI0.GFX0 Display ACPI Path: _SB0.PCI0.GFX0.DD02 Used kexts: WhateverGreen and Lilu, latest versions It boots fine with any graphics ID except for 01660003 and 01660004. Although, internal display is recognized as external, so Night Shift isn't working, and, I believe, this causes issues with backlight. Spoiler Hackintool shows this info (ig-platform-id = 0x01660002) Spoiler Booting with 0x01660001 enables both displays, internal and HDMI, however, internal one is still treated as external Spoiler Booting with 0x01660003 enables only HDMI - internal display showing verbose log up to IOConsoleUsers string, then turns black - but backlight is still on Spoiler 0x01660004 normally boots to the same place - verbose log up to IOConsoleUsers. If I patch second connector as HDMI, it recognizes HDMI display and brings it up. Internal one is going black again Spoiler So, internal display isn't recognized with any ig-platform-id - even if it works, it works on dummy connector and as external. At this point, I'm totally stuck. Anything that could help with this? Also, attaching IORegs (IOReg + last 4 digits of ig-platform-id) and current Clover folder.

Myp3a Posted August 29, 2020 Author Share Posted August 29, 2020 After messing around with remote display, it looks like GPU is fully working, but display is not detected. Graphics/Displays: Intel HD Graphics 4000: Chipset Model: Intel HD Graphics 4000 Type: GPU Bus: Built-In VRAM (Dynamic, Max): 1536 MB Vendor: Intel Device ID: 0x0166 Revision ID: 0x0009 Metal: Supported, feature set macOS GPUFamily1 v4 Injecting EDID that I extracted from Windows does nothing. Hackintool shows no displays. How can I inject display data or make it appear in system?
