[SOLVED] No video output after bootloader. GTX 1050 ti on a z97x, 10.12.6

Hi guys, posting in the forums is usually my last resort, but I'm really on a dead end here.

A friend of mine gave me his system to update the GPU, he moved from an ASUS gt 620 to a very cool Gigabyte 1050 ti.
Thing is, I can't seem to make it work.
I've put together a bunch of hackintoshes before and come across this same problem every now and then, but the usual solutions always did it for me.

Now I'm just stuck on a black screen after the apple logo if I select the Web Drivers from the Nvidia application.
System's still responsive, just no image.

Specs are the second build on my signature ("Friend's build").
Running Sierra 10.12.6
Using HDMI
Trying to run WebDriver-378.05.05.25f10
Initial Display Output on BIOS = PCIe 1
Onboard Graphics = Disabled
SIP = 0x67
NvdiaWeb = true
Updated Clover to add EmuVariableUefi-64
Lilu and WhateverGreen are installed
nv_disable=1 takes me to the desktop.

I'm sure I'm missing something, but I can't quite put my finger on it. That's why I'm here.
Adding the *.plist for your convenience.

Thanks everyone for the great job!

Don't ask me why, but tried every HDMI output of the GPU (it has 3) except for... the first one.

That was the problem, installation was fine as usual after all... it turned out that ports 2/3 won't work as primary outputs.

Lost a solid 4 hours on this xD
But at least my friend will have an updated clover and some minor tweaks.

SOLVED!
