Gigabyte Z390 UD + i5-9400 HDMI Black Screen Problem (Catalina 10.15.5)

[svValentyn]

Hi. Can not fix video on Gigabyte Z390 UD + i5-9400 (no external graphic). The motherboard have only one HDMI and I do not have external graphic card.

-------------------------------------------------------------------------------------------

Currently I can achieve only this results:
a) Unrecognized graphic device with 7MB memory and no acceleration.
b) Black screen after [IGPU] section on boot ( no signal message on monitor).
c) Screen stuck after [IGPU] section on boot.
d) Intel UHD Graphics 630 7Mb (no acceleration, hackintool detected connected monitor as external).

Next kexts are present: AppleALC, Lilu, VirtualSMC, WhateverGreen, USBInjectAll, RealtekRTL8111.
Sound and gigabit connection are working.

In UEFI possible values:

• DVMT -Pre-Allocated: 32, 34, 96, 128, ...(many more)... 1024
• DVMT Total Gfx Mem: 128, 256, MAX
• Aperture Size: 128, 256, 512, 1024, 2048

Spoiler: Examples:

• (GFX IGPU) + (MEI IMEI) + (HECI IMEI) + (IntelGFX 0x3E9B0007 / 0x3E920000) + (InjectIntel) + (ig-platform-id 0xE9B0007 / 0x3E920000) + (iMac15.1 / macMini8.1) = Unrecognized 7MB.
• (ig-platform-id 0xE9B0007 / 0x3E920000) + (iMac15.1 / macMini8.1) = delay after [IGPU] section and screen off.
• (InjectIntel) + (ig-platform-id 0x3E9B0006) + (macBookPro15.1) = stuck after [IGPU] section.
• (ig-platform-id 0x3E9B0000) + (macBookPro15.1) = delay after [IGPU] section and screen off.
• (InjectIntel) + (ig-platform-id 0x3E9B0000) + (macBookPro15.1) = after [IGPU] section screen off.
• PATCH (0x3E9B0000) + (3x connections -> HDMI) + (connectors) + (DeviceProperties) + (VRAM) + (EDID) + (Graphic Device) + (All) + (Use AllData Method) + (Use Intel HDMI) + (HDMI 2.0) + (Spoof Video 0x3E9B) + (macBookPro15.1)= after [IGPU] section screen off.

• PATCH from this post. + (iMac19.1) = Intel UHD Graphics 630 7Mb (no acceleration, hackintool detected connected monitor as external).
• PATCH from this post. + (with and without memory fix and other) + (iMac19.1) = Intel UHD Graphics 630 7Mb (no acceleration, hackintool detected connected monitor as external).
