I have connected it to my RTX2070 card, and it seems to work, all the way up to 115Hz @ 2560x1440p. All this without using your fantastic utility, so far!!!

However, I am having problems with the nVidia control panel not letting me select 120Hz, (which the monitor is capable of, with a GTX970 using a native DVD-DL connection) as it looks to be fine, and gives me the usual dialogue box asking me if I want to keep this resolution etc, which I click yes on, however the control panel does not "save" this in the list of available resolutions, as if I did not press yes. Do you think this is an nVidia bug, or does my display driver need to be patched with your utility?

You are probably hitting a bandwidth limitation. You probably need to stay under 476 MHz pixel clock. That should be possible if you reduce the vertical total to 1450. Also, it's likely the color depth is only 6 bpc beyond 357 MHz, but it shouldn't be too noticeable if it's dithering.
