Hi there, my CPU is i5-8250U and when I plug HMDI cord in my laptop and in my monitor - nothing happens at all. The cord is functioning because I was using it when my laptop had linux installed and everything worked okay.
Here is what I've tried to do:
1. In the DSDT section of my config.plist I've changed 47465830 with 49475055, it should had changed GFX0 to IGPU or something like that.
2. Change 48454349 to 494d4549 (change HECI to IMEI)
3. Set IntelGFX field of the Fake ID (in the Devices section) to 0x59168086
4. In the Graphics tab I've checked Inject Intel and set ig-platform-id to 0x591b0000.
Then I've saved the config.plist.

After that I've downloaded FakePCIID kexts and installed it into Library/Extensions and rebooted my laptop.
It didn't even brake the system, it just did nothing, or at least it looks to me like this =(

Here is an archive with all the info :thumbup:
