Should I have restored the backup patch before running the full maybe? I ran the full and just patched whatever was missed from the regular patch.

It doesn't matter. The green horizontal lines indicate a signal quality problem. Try manually reducing the totals to 2664x1450. You can probably tweak it down a little further, but that will give you a good starting point.

What is an appropriate amount to tweak this total pixel field by? I still get a green line very rarely so I'm guessing I need to adjust it a little more.

I think the lowest horizontal total that works with the QNIX is 2652. If you set the vertical front porch and sync width to 1, you can set the vertical total to 1445, or possibly 1444 or 1443 if your GPU can handle that low.

Toasty thanks in advance really love what you are doing to help us get to 120hz. (I will continue to donate as well). I have a minor issue but its bugging me.

I have two 780's with a custom vbios and 331.82 drivers and even in the last drivers BF4 (have not checked others games yet) will not see the 120hz unless i remove the custom resolution then re-add to the Nvidia control panel.

My process is this:

New driver
Patch
Apply Custom resolution/refresh
Go into SLI
Apply custom resolution/refresh
Apply Precision X fan/Frame Cap

I then start up BF4 and go into the video options and only 60hz is available (59.something actually)
If I tab out nvidia control panel show it at 120hz and i hear coil whine with a white background
once back in game the nvidia control panel will drop to 60hz
I then delete the custom resolution/refresh and it will then work. Any suggestions? Thanks in advance

Try removing GeForce Experience. Have you tried using CRU?

Geforce Experience -I saw one of your post about it being an issue so I do not install it. I only install the base drivers and physics drivers.

I have CRU but have never tried it since the control panel was working until recently fine for me.

Do you suggest it over the Nvidia control panel option?

[ToastyX]

There might be a driver bug with custom resolutions and SLI. CRU uses a different method to add custom resolutions, so it might not be affected.

Hey, over @ 120HZ.net, they are saing you no long need this with the latest NVIDIA drivers? Is that true...?

I was experiencing constant driver halts on 320.49, but I hear that's common, I tried the latest and had the same experience.

I went to 314.22, recommended to be some of the last good oens - same thing.

But now, the idiot that I am, I think my timings may be the reason it was crashing.

[ToastyX]

The patch is needed if you use CRU, and the full patch is still needed for SLI with most cards. The GTX 780 and the Titan might not need the patch for SLI, but I don't know for sure.

Quote:400/500-series GPUs will not reduce clock speeds on idle if the pixel clock is greater than 404 MHz.

Is there any known workaround to this issue (aside from reducing pixel clock, obviously)? It makes my GPU idle quite a bit hotter. I don't run at 120 Hz all the time, so it's fairly minor, but I'm curious about this.

Also, thanks ToastyX for the awesome tools.

No workaround other than getting a newer video card.
