Custom Resolution Utility (CRU)

Quick question... I'm using an LG 34GN850 which is 3440x1440 (native) and supports 60, 100, 144, and 160 Hz refresh rates. It does not support 120 Hz.

However, when I use CRU to add custom resolutions that are higher (3456x2160 with 60 and 120 Hz), the Nvidia control panel automatically adds 120 Hz for 3440x1440.

Is this a bug? It seems like Nvidia assumes if my monitor supports a higher resolution at the same refresh rate then it must be supported at a lower resolution.

If I test 3440x1440 @ 120 Hz, the monitor freaks out so it really doesn't appear to be supported which seems very strange but regardless...

This is normal behavior for refresh rates in Windows. Refresh rates are automatically propagated down to lower resolutions by the graphics driver as scaled resolutions. I don't see why the monitor would freak out because it's supposed to be scaled to the higher resolution.
