GUIDE How to Enable Intel Skylake Graphics (Intel HD Graphics 515, 520, 530, 540, 550 and 580) on macOS Ventura and Later

[Kpbicka]

On your advice, I removed unnecessary lines and defined 2 connectors:
0 - a monitor is connected to it
1 - must be HDMI
System boots normally but HDMI does not work

When I changed framebuffer-con0-type from value 0200000 (LVDS) to 00080000 (HDMI) - see screenshot - then nothing happens - after reboot the image is still on the screen, although I thought it should disappear, I conclude that the patch does not work. Why?

You cannot expect it to work as the ig-platform-id and device-id values are not as per the guide. The guide states to set the following values

ig-platform-id = 00001259 (Desktops) but you're using Mobile ig-platform-id.
device-id = 16590000 but you're using 1B590000

Moreover, you're looking for Mobile Connectors.
Set the con0 to 00040000 and HDMI to 00080000.

As I said earlier I use laptop-id because I have laptop-board with integrated (built-in) display connected via LVDS bus. If you use Desktops ID then no display will be detected on any connector (in IOReg) and the image is missing.
I checked your configuration option (screenshot) and applied different platform-id and device-id - no change

The values depend on the CPU, not the motherboard.
If you don't see any images (probably, display), you need to patch Bus IDs.

Simply set con0 busid to 01000000 and con1 busid to 04000000

Here is the config you asked for:
con0 busid = 01000000 and con1 busid = 04000000

and earlier asked:
ig-platform-id = 00001259 (Desktops)
device-id = 16590000
con0 = 00040000 and HDMI to 00080000

Nothing happened - Mac OS boot into black screen, only ssh can connect, no Apple Remote Desktop this time connected - GUI not loaded

So, LVDS boots into blackscreen and still no HDMI?

Yes

 

[EliteMacx86]

Yes

Change the following.

con0-busid = 05000000
con1-busid = 02000000
con1-flags = C7030000
con1-index = 01000000

 

[Kpbicka]

Change the following.

con0-busid = 05000000
con1-busid = 02000000
con1-flags = C7030000
con1-index = 01000000

Done. But same shit.
No LVDS signal, no HDMI signal
For undo changes I login via Apple Remote Desktop from another Mac.

Are you sure your HDMI port is in a working state and no dGPU exists on the system? Also, are you using a certified HDMI Cable?
