I'm trying to convert a HP EliteDesk 800 G4 Small Form Factor PC into Hackintosh. I've sorted out most of the things on this machine except the in-build UHD630 iGPU. Currently it shows as "Intel UHD Graphics 630 1536 MB" and works flawlessly until it blinks (screen goes completely dark and comes back). I've noticed this happening right after the sleep and reboot.

Another problem is the display settings has only 1080P and 4k resolutions but intermediate 1440P etc resolutions are missing.

Configuration:
  1. CPU: Intel i7 8700
  2. Motherboard: Q370
  3. OS: Mojave 10.14.6
  4. Video output: 2 DP and 1 VGA
  5. Clover Plist: <I'll attach>
  6. Clover Plist configurations modified for GPU:
    1. Devices -> IntelGFX -> 0x59128086
    2. Graphics -> ig-platform-id -> 0x59120000
    3. SMBIOS -> 18,1
NOTE: I know these for Kabylake CPU but these are the only configuration which got me the graphics acceleration.

Kexts used (/Clover/EFI/../Other)
  1. IntelMausi
  2. Lilu
  3. WhateverGreen
  4. USBInjectAll
  5. VirtualSmc
  6. VoodooHDA
I've seen the Hackintool Framebuffer patching but when I connect and disconnect my monitor DP cables it doesn't highlight the row in red. I tried for 3-4 hours and gave up.
