How are you connecting the monitor? The GTX 1070 shouldn't have VGA, so are you using some sort of adapter? There might be a pixel clock limit with the adapter.

I'm using this adapter. I think you're right. Here's the resolution in nvidia control panel, where it does apply and work properly.

Sometimes the driver applies pixel clock limits to EDID overrides but not the NVIDIA control panel. I can't do anything about that.

Well I'll mess around with the pixel clock patcher later. Thanks for your help!

Hi, I'm setting up the new 3440x1440p 144Hz LG 34GN850-B and I'd like to set the same refresh rate of my secondary 144Hz 1920x1080 monitor with a custom resolution so my GPU will not have high clocks in idle, but when I try to edit the single detailed resolution available (also I don't know why it's 99Hz) I'm not able to set 144Hz. I've already set the right refresh rate in the Nvidia Control Panel and in Windows settings. Am I doing something wrong?
Thanks!

Pixel clocks beyond 655.35 MHz need to be defined in a DisplayID extension block, which is probably what the "Default extension block" is. For some reason NVIDIA's driver will not read more than one extension block. Secondly, I'm not sure you can avoid high idle clocks with mismatched resolutions because there's no way to synchronize the monitors without making the totals the same, which would be too much for the 1920x1080 monitor.

I would have imagined that I could not have solved this way. Do you know if there's a way to set my primary monitor to 120Hz even if there are only 60, 100 and 144Hz options in the Nvidia Control Panel? Can I do this with CRU?

You can add 120 Hz with CRU.

I created a detailed resolution at 120Hz, but when I close CRU and launch the restart.exe or restart64.exe the result is always the same: can't see a new resolution in Nvidia Control Panel, and in CRU I see two copy of the monitor, and the one with the new resolution has an * like if changes aren't saved after the restart.

* means changes are saved. I don't see why that wouldn't work.
