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.

The problem with 96 Hz sounds like a driver bug related to memory clock changes and link retraining. You're getting blue and green because that happens to be the colors of the wallpapers on each screen.

The 50 FPS issue sounds like a driver bug related to desktop composition with multiple monitors. In Windows 7, you can check by switching to the basic or classic theme to disable desktop composition. Windows 8 doesn't have a way to disable desktop composition. The problem might not affect full screen games. You'll have to check the frame rate in games to make sure.

Those are issues that NVIDIA has to address. Try installing the latest beta (326.80).

The patch isn't needed for a single GTX 780 if you're using the NVIDIA control panel to add higher refresh rates, but many games won't use the higher refresh rates unless you install this: https://www.monitortests.com/qnix.zip

Install it using the Device Manager: Right-click the monitor -> Update Driver Software... -> Browse my computer for driver software -> Let me pick from a list of device drivers on my computer -> Have Disk... -> Browse for the .inf file -> OK -> Next -> Install this driver software anyway

If you're using Windows 8, you'll have to temporarily disable driver signature enforcement first: http://sixcolumns.com/t/how-to-disable-a...dows-8/151

That won't work for some stubborn games. CRU is a bit more effective. If you want to use CRU to add higher refresh rates, you'll have to use the regular patch at least. The full patch isn't needed for a single GTX 780.

Thanks Toasty, yes it had something to do with the drivers and the desktop composition. I get mixed results but I am able to get 120Hz on my gaming monitor. I will just wait until they update the drivers. Thanks a lot!
