[Solved] Kaby Lake - High Sierra: Issue dual monitor with integrated gpu

[dr.floyd]

Hello everybody,

The premise is: I'm new ... Therefore I hope my question is not too dumb.

I've tried many possible suggestions that I could find on the web on this topic without success. Most of them on this site, although mainly about issues with Sierra.

My problem: I'm trying to make two monitors work on the graphics integrated to the Kaby Lake i7 but I can't.
I have Gigabyte GA-Z270X-Ultra Gaming mobo and using 1 DVI and 1 HDMI. If both monitors are plugged before booting, system can't boot. If I plug only DVI system boots correctly and graphic acceleration works fine. If I plug HDMI with system already running, system crashes.

I attach my config.plist really hoping somebody could help.

Thanks already!
