Hardware acceleration not full intel HD 620

[EliteMacx86]

Here are the PR files with the ig-platform-id 00001619 so skylake. I only have internal screen working without hdmi and 5mo VRAM without graphics acceleration.
The EFI is splitted into 2 files because of too big for the website

Why are you using SSDT-PMC? It's not meant for KBL.

Also, the correct ig-platform should be 591B0000.

I thought it will fix the shutdown issue but not.
I attached PR files with 591B0000 and removed SSDT-PMC.
Only the external screen work, the internal screen is well detected, brightness control work, resolution is ok (1600x900) but I have a black screen...

It would good if you prepare the EFI from scratch.

Is your BIOS updated? What's the internal display connector?
