Hardware acceleration not full intel HD 620

[Lucpop2007!]

Hi everyone !

I am facing with a problem with Monterey 12.1 with OpenCore 0.7.5.
I have successfully install it but I have glitches on the internal screen, the dock isn't translucent like QE/CI is not fully activated.
I have no HDMI Audio too...
I have tried many patches, tests but nothing worked, can you help me ?

I attached my config.plist and a screenshot, I think I have trouble with device-properties.

Incomplete PR files attached.

IOReg, Kextcache Output and EFI folder is missing. Also, are you sure that your screen resolution is 1600x900? It should be probably between 1366x768 or 1920x1080, unless its 4K/UHD/QHD.

Oh yes I forgot these. I attached them.
Yes I am sure that it is the max resolution for this laptop, you can check on the screenshot.

As per the files, the VRAM is working. Although, the platform ID you injected is for Desktops. For Laptops, the ideal Platform ID would be 00001B59

I tried 2 patches :
- replaced 00001619 with 00001B59 -> No HDMI, no internal screen and brightness doesn't work

- try another device-properties with 00001B59 -> graphics works perfectly, HDMI Audio works, brightness works but internal screen still black.

I attached IOReg and a screenshot of the new device-properties.

You shouldn't need Device ID.

Add igfxonln=1 to your boot args and then check.

Are you sure there is no Display instead of any no Brightness?
