Hi everyone,
it's a couple of day that I'm trying to install 10.13.4 on my new build.

I had a lot of problems especially with the iGPU, now I found the actual problem:
When I set-up the platform-id= 0x5912000 and intelGFX= 0x59128086 and reboot, the result is the "black screen" with no signal (using HDMI) though the system works perfectly.
I verified this with screen sharing and the GPU is perfectly recognized with 1536MB VRAM.
There is a way to correctly "redirect" the video signal? I heard that it could be a FrameBuffer problem...

I attach the screen of 1 port of “AppleIntelKBLFrameBuffer”.
Others ports have id = 0x5 and 0x6
All have connector-type= 00 08 00 00.
Try ONLY this patch

In this motherboard display port works at port 0x5 and without patch is
not posiible get HDMI output signal.

HDMI works on port 0x6 but for UHD 630 this patch redirect hdmi to 0x6 port too.

Important ! Only ONE monitor can be connected .
With Two monitors (HDMI&DP) is something workaround. For example connect first HDMI display,
DP display must be power off (from the power outlet). Next when Mac OS is ready on HDMI Display
turn on DP display (from power outlet) then switch off HDMI display and turn on HDMI display.
Now You have two displays ready to work !

Greetings Everyone!!

My problem is quite similar, with additional glitching that starts halfway at the boot after which the HDMI screen goes blank and the boot continues on the VGA monitor. the OS version is 10.13.5.
the only difference is that there is no DP but a VGA port instead. The ports are HDMI,DVI and VGA. With full hardware acceleration only the VGA works on port 0x5, the HDMI and DVI black out during boot. I have attached the config.plist and EFI files.
The full acceleration was achieved by adding the following to Device properties
"IntelGFX - AAPL,GfxYTile-0AAAAA00-DATA"

I have tried changing the Mac model to 18,1 18,3 but of no help too many glitches and the problem persists

I have even tried this but it doesn't work. The screen goes blank halfway through the boot

Try ONLY this patch

Update!!

The DVI port is working. HDMI goes blank during boot.
I tried changing the igfx to 0x3e928086 and Mac to Mac18,1 both ports work but acceleration is gone.
Realized didn't need IntelGFX - AAPL,GfxYTile-0AAAAA00-DATA" for hardware acceleration. It only works when igfx is 0x59128086 and Mac is 17,1

Please help


Update 2

After going through a lot of threads, finally tried Rehabman kext for 0x3E9 along with putting the lilu and shiki kext in L/E and changing SYMBIOS to 14,2 and lo behold the DVI works with proper resolution and zero glitches and full acceleration.
The second monitor doesn't work (HDMI) but I can live with that for now.!!

I'm having a similar problem I can only get one monitor at a time to work. on clover both work HDMI and DVI till apple logo then DVI monitor drops out. both ports are definitely recognized I can boot with either as long as the other is disconnected. plugging either after fully loaded doesn't get them to work either. I need clear guidance to get the ports sorted and work together.
anybody please help.
