mobo: Gigabyte z97x Ud5h
cpu: Intel i7 4790k
gpu: EVGA GeForce GTX 970 (FTW)

No signal after the loading bar reaches halfway.
Can only boot into Sierra by disabling the nvidia drivers (nv_disable=1).

Any help would be appreciated as ive been trying to get this to work for a little over a week now.

Things I've tried so far that didn't work:
-NvidiaWeb=true in system parameters
-nvda_drv=1 unticked in cc
-SMBIOS: iMac13,2 iMac14,2 iMac 15,1 MacPro4,1 MacPro5,1 MacPro6,1
-AGPDfix when using iMac15,1 and MacPro5,1

@rafferli, please update your profile (personal details) with your Motherboard or Make/Model, CPU and Graphics Card.
The Rules said:
Profiles need to contain at least your primary system to assist others with helping you.
BIOS - Disable Integrated Graphics - PEG as Primary
Use a digital connection - DVI or HDMI - VGA is not supported.
Config.plist - Do not inject Intel or Nvidia graphics and no ig-platform-id
Edit config.plist - NvidiaWeb = true as per Link
Gigabyte 100/200 series motherboards need to emulate NVRAM - Problem 6 (Install EmuVariableUefi-64 + RC Scripts)
Remove nv_disable=1 from config.plist
MacPro 6,1 or iMac 15 or iMac 17 System Definition need black screen fix as per Link
