QNIX 2710 monitor - Help me please, ideas?

[dseg]

Hello,

I bought two QNIX 2710 monitors and overclocked both to 120Hz easily on my nvidia 580. I was able to run the tester with no problems on both screens (getting 120 FPS) and even run them at the same time (one on each screen). Here is a screenshot of when I had both monitors on the 580 LINK

I just upgraded to the 780 yesterday and now I am having weird problems.
So I had to re-overclock them because it wiped my resolutions out when I switched to 780. So I can overclock both monitors to 120Hz but if I run the FPS test on both screens at the same time, my FPS average in the 50s on each screen. If I run each one separately at a time, I get 120 FPS. Picture

Now, if I overclock both monitors to 96Hz, both screens freak out and one goes solid blue and other goes solid green. So I started to experiment with overclocks:
I used this tester for Hz and FPS

If I set one monitor to 120Hz and the other to 96Hz. both average 50FPS
If I set the OTHER monitor to 120Hz and the OTHER monitor (just switching monitor OC above) They both show 96 FPS on both of the screens at the same time.

If I set one monitor to 96 and other to 60 - both average 50FPS
If I set one monitor to 120 and other to 60 - both average 50FPS

If I set them both to 60Hz - both average 50FPS
If I set them both to 120Hz - both average 50FPS
If I set them both to 96Hz - I get a flashing/solid blue/green screen.

I tried switching cables, power supplies, the obvious things. I don't think I need to do the Pixel patch since I am getting an OC already, correct? I tried reinstalling drivers. I am not sure what else to do.
I do not think it is anything with the screens because I had this stable on my 580 (gaming for weeks). But as soon as I got the 780, it has been problems.

I also OC'ed each one separately (using only one screen at a time) and had no problems getting 120 FPS/Hz. It's when I hook them both up that I have problems. Why wouldn't I get 120FPS or even 96FPS (96Hz is when screens just turn solid colors) on both screens at the same time? I would say my graphics card, but if my 580 can do it, the 780 should deff be able to do it.
