HD4000 LVDS black

[Myp3a]

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

Spoiler: Boot log

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.

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?

I see you are setting your id under device--> properties, I would try to set it under 'Graphics' and also Inject Intel...

set it under 'Graphics' and also Inject Intel

The same. I've tried...
1. Setting id with ig-platform-id
2. Setting id with igfxframe boot argument
3. Setting id with device properties
4. Setting Mac model and let system choose id
Everything goes up to graphic initialization, iGPU runs, but no display detected and I'm getting a black screen
(01660003, 01660004 id's)
