High Sierra 10.13.6 HD 4600 4k / VRAM Help

Hello all

Specs:
Dell Optiplex 9020 SFF
i5 4590
HD 4600
840 Samsung 120gb SSD

OS: High Sierra 10.13.6

I am using DisplayPort with a DP to HDMI converter.

So I have narrowed down my problems that I am occurring.

  1. Whenever I put 0 or 0x04128086 as my IntelGFX, the system boots great, but in low resolution. It says it's 1080p but definitely does not look like it. I can switch it to 1440p in Display settings but it only looks slightly better.
  2. Whenever I change IntelGFX to 0x012345678, system boots in 4K but I only have 31MB in VRAM on my HD 4600. I am unable to change the preallocated DMVT in my BIOS, very limited in settings.

I have googled both problems and tried multiple solutions:

  • Tried following a 4K enabling guide from a reddit post here: https://www.reddit.com/r/hackintosh/comments/3zt8ti/4k_uhd_with_hd_4600_displayport/
    I am not that knowledgable with clover configuration. Either I did not follow correctly (as I'm not sure I'm following it correctly.) OR it doesn't help my system.
  • Tried reading and following changing DMVT preallocation of VRAM. Either the methods I try don't work (Installing kexts like IntelGraphicsFix.kext or framebufferazul.kext from youtube videos such as this one: https://www.youtube.com/watch?v=PYuTSPzqQnw)
    The other ones I found talk about changing binary code and I get completely lost.

I will post my EFI and anything else you need. I don't have anything in my Library/Extensions folder. Should I? Thank you.
