[Solved] Dual Monitor for on-board HD 630 graphics with 10.12.6

[nijat12]

Hello I finally managed to get on-board Graphics working with following:

ACPI : patches : Rename HDAS to HDEF and Change GFX0 to IGPU.
Boot : flag : -shikigva=1, -disablegfxfirmware
Graphics : Inject Intel checked and ig-platform id :0x59120000
Device: IntelGFX: 0X59128086
SMBIOS : iMac 18.3
IntelGraphicsFixup.kext, Lilu.kext and Shiki.kext.

But i still have an issue when i try to connect the second monitor.

My mobo has an Hdmi and displayPort outlets. I want to run 2 monitors without a graphics card (using on-board graphics of i7-7700K)

I tried plugging the monitor after boot and the second monitor came on patchy for couple of seconds and then the computer would crash.

PLease help


Edit: The issue was SMBIOS. I put 18.3 instead of 18,3. I guess Apple uses a comma instead of a period in their versioning. Once I changed that both monitors work fine. Now the only thing i need to figure out is to have them work from start instead of having to plug them in afterwards
