(Fail) High Sierra - Clean Install GA-Z77-DS3H & i7 3770k

[Torrijos]

Hello guys, so I am a proud user of a very nice and functional Hackintosh, BUT after years of usage I'm starting to get a bit worried and want to make sure I haven't loaded up some craps on the way.

So my goal is :
- To make a clean install on a secondary SSD, with the least possible changes and Kext added.
- Once that system is stable to copy back the EFI partition to my main drive

Where I am :
- I made a new UniBeast boot drive
- I finished the installation process of High Sierra.

First Issue :
- Using the boot key as a boot loader one of my displays gets stuck on the Apple logo loading...
So I have
AMD GPU -> Display 1 (2560x1440) WORKING
iGPU HD4000 -> Display 2 (1600x900) STOPS WORKING AT Apple logo

Display 2 (iGPU) works during BIOS or booting BUT then, at the Apple loading bar, it gets stuck
Display 1 (AMD GPU) gets alive at the Apple Loading Bar
- My problem is that the iGPU display is considered as principal so the configuration windows (or login prompts) are on that display.

Any idea what might be happening?
Attached the UniBeast boot key config.plist (I tried changing the resolution just in case it was that but without luck)

Any chance for help I'm sure it's just some setting wrong in the config.plist

I see someone moved this to graphics...
It is supposed to be more of a guide once it's finished, but why not ^^

So any advice on this? I'll try this week to touch only graphics Settings (radeoninit and Intel ID)
