Need help with intel HD 630

[Jackson Lino]

-Motherboard: Intel Cannon Point HM370, Intel Coffee Lake-H

- CPU: HexaCore Intel Core i7-8750H, 3900 MHz (39 x 100)

- iGPU: Intel(R) UHD Graphics 630

boot-args:    -v -wegnoegpu alcid=28 -cdfon -igfxblr

AAPL,ig-platform-id: 0900A53E
device-id: 9B3E0000

 

The graphics is all messed up and can't read text.

 

 

I've tried almost everything.
Maybe the problem is with the monitor, because when I take the printscreen, the image comes out perfect

Thanks!!!
Added the attached config.plist.

I tested the following patches
adaugherity/patch-edid.rb
ejdyksen / patch-edid.md
WhateverGreen/Manual/edid-gen.sh

• property: AAPL00,override-no-connect
• type: DATA
• Value:  00FFFFFFFFFFFF0009E5950600000000011A0104952615780A3750A5554E9C26105054000000010101010101010101010101010101013C3780DE70381440302036007CD21000001A302C80DE70381440302036007CD21000001A000000FE003939443439804E5631374E3431000000000001411196000000000A010A20200099

 

None of them solved the problem

According to the attached screenshot, the amount of bit depth supported by the monitor is 6 bits per primary color, total of  18 bits  and on the mac it was 24 bits, so the screen is getting distorted.

Are there any solutions for this?

 

I'm losing hope this works.

- I set up a new efi for laptop and the monitor was recognized as an internal monitor

- I tried all PlatformId below, the Platform ids: 0x3EA50004 and 0x3E9B0006 got black screen

- I still have the same problem

 

 

 

 

 

 

- Attached, the data generated IOregistry and the new config.plist

-> What about without the -igfxblr boot arg?

Answer: The screen is black if you don't use the -igfxblr argument

-> Did you try the EDID script if simply injecting the collected value changed nothing?

  Answer: I've tried it doesn't change anything, from one script to another it changes little

 

-> NB: young inject SSDT-XOSI.aml table which presumably defines the usual XOSI method, yet your config shows no renaming of _OSI to XOSI. As such, there's little chance that news method will ever be used. I also noticed you added a path to that table and same for a couple of kexts; unusual but I guess you must have used subfolders...

  Answer: I removed, I left only what was necessary

 

- Almost everything is working.
- Hdmi was 100%
- The laptop screen remains the same, I applied several solutions:
Many device-id, AAPL,
Many ig-platform-id,
Many "AAPL00,override-no-connect",
  WhateverGreen - editd-gen.sh,
  Framebuffer Patching Guide,
ejdyksen/patch-edid.md,
adaugherity/patch-edid.rb
etc...
They all like the same problem.

I'm almost accepting that there is no solution for this case, because the HDMI external monitor works perfectly.

 

An interesting thing I noticed is that in the first second the screen is displayed perfectly and then the colors change, maybe it's too much white light. Follow the link of the video displayed this effect:

Why on earth do you inject DP connector type to your LVDS built-in LCD connector? 😲

 

-> Regardless of injecting the port (02000000) or (00040000) or not injecting anything in con0, the result is the same

-> My monitor is displayed in windows 10 on DisplayPort input, as shown in the image below

 

For the HDMI to work I had to make several combinations until I got the following result;

Hdmi only works when injecting the value 02021000 00080000 C7010000 into Con1 or con2

Color bit depth .... 6 bits per primary color

It is what you see. Try to change EDID such a way it will be 8 bits per color. Or change matrix.

[Jackson Lino]

I injected edid in two ways:
