Can't get dual screen to work with NVIDIA GeForce GTX 650

Hi, I'm pretty new to Hackintosh, actually to OSX in general (well, used it for a year at work due to being an iOS mobile app developer).

Anyway - pretty recently I decided to clean setup my desktop, with dual boot Windows and OS X. Windows 10 and OSX 10.10 to be exact (all the tens ).
The Windows setup went just fine, so did the OSX (using UniBeast). Then I read I have to install Clover to be able to boot into both with just my internal HDD (is that true? I used to have I think it's called Chameleon, but that was ages ago, and with Windows 7 alongside).
As long as I'm booting through my external USB and the UniBeast tool, both of my screens get detected and work just fine. Booting through Clover seems to work fine - bootloader shows up on my primary screen (well, I actually have them switched up, will get into details below), so does the OSX loading screen (which is pretty slow, probably due to kext caching being disabled or whatever, I had to do that to be able to even boot), it gets to 1/4 or 1/3 of the progress bar, then the primary screen just turns off, secondary screen turns on and is being used by OS X.

My video card is NVIDIA Geforce GTX 650, with 3 outputs: HDMI, DVI and VGA. Now, my primary monitor is connected via the VGA output and secondary via HDMI, with a HDMI->VGA converter (digital -> analog) (unfortunately, neither of my monitors have HDMI inputs). The reason for them being switched up (usually the primary monitor should be used via HDMI, right?) is because apparently the converter I'm using here isn't very good and causes some light blurred effects around text and other contrasting shapes being displayed - I don't really mind it that much if it's on the second screen.

Attached my Clover config.plist file. I tried many different and odd things to get it to work, to no avail, so the file can be really odd now - I wouldn't know though, I'm really a newbie, so bear with me here.

Any ideas what could I do about this all? I just really want to have a working dual boot setup with Windows 10 and OSX 10.10, both with dual monitors, without having to boot OS X via USB.

OS X doesn't support VGA. When booting with Clover the video is displayed using the VESA Mode for the card which supports VGA. When the drivers for OS X load then HDMI is supported which is why that port turns on.

Okay, I could understand that - why do both monitors work just fine if I boot OSX through Chimera (as that's apparently what the UniBeast bootable USB uses)? Could I possibly achieve that with Clover?

I have similar problem with my 650 Ti Boost, which I had... I don't remember exactly what was the problem, but I think something about not working displayport or what and I discovered, that it was because I'm injecting nVidia in Clover, when I disabled it, it started working great as well as (thing, which I doesn't care about, when it works) in About This Mac I had 0 MB VRAM, which changed when I disabled nVidia injection.

but never get VGA working (what is probably good, because it is a bit discrimination of this oooold port, which should be gone for years ago)

Yup, removing the "injecct nvidia" option solved my problem on dual display. I have the same GTX 650 Ti Boost, and for the record: I have one dvi display and one avg display with a dvi adaptor. Both are being recognized and they're working fine.

VGA is supported, seems: i was use dvi 1920x1080 and old 15' vga 1024x768 on msi gtx 750 ti in El-Capitan 10.11.5/6
until now. after the next restart, the second monitor just isn't determined by the system
so i have a similar question

VGA not being support by OS X does not mean that it absolutely cannot work: Depending on the specific GPU model, VBIOS, driver revision and OS X version it might work. But it can also easily break after a driver update (or other actions) without any note.

If you didn't change your setup, we can't help you. I'd suggest using a DP to VGA adapter if you really need that ancient technology.
