Blank screen during boot with display port (with GTX 1070)

[daulex]

Installation method: Unibeast/multibeast.
MOBO: Msi Gaming 3
Video: GTX 1070
Cpu some oldish i5 @ 3.3ghz

I went through the installation process with my main screen (using display port), but without Nvidia drivers loaded I think (had safari gfx glitches, animations were slow).

Installed Nvidia drivers and upon restart, once the bar goes 60% way there, screen blanks out and that's it. in -v, it goes too fast to read, there are no panics, the display just loses feed and it's gone.

Now if I pull out the display port lead and restart with just my second monitor (using dvi-d), the screen also goes at the same spot(I think that's when Nvidia drivers take over, although I saw some text about Nvidia web driver in -v closer to the start of the boot process), but the apple logo re-appears a few seconds later and I can then see the login screen.

Now, what's even better: if I plug in the display port after boot/login, the system detects it and runs it correctly, I can even set it to 144hz mode (which this display supports) and everything works fine(both displays concurrently, see screenshots)... Till I reboot.. Then the same thing starts all over again.

I'm not sure what info is required, but I took screenshots of everything that I know that might be useful and attached them.

Will appreciate any pointers in getting this to work without having to pull out the display port cable to boot. Please ask if there is any info or anything I can do to supply any required information.

May need to install Lilu.kext and NvidiaGraphicsFixup.kext to /Library/Extensions

Ok, I've installed both, using kext wizard, no noticeable change.

Did I also need to do something like -v -f, or is that done automatically these days?

Edit: actually, here they are, already loaded. So, that didn't do the trick. Any other things I can try?

Edit 2: I figured out that if I simply switch off the display port display, before booting, boot happens on the dvi-d device and then I simply turn it on when I'm logged in. I mean this ain't pretty, but it's better than the stuff we had to go through in the olden days. I'd still love to get this resolved if anyone has any ideas though
