assuming the jpeg i posted above, can you tell me what steps you would take to accomplish the following using windows 10 and a nvidia card (2080 ti, latest drivers):

- create a 1920x817 custom resolution.

- have this custom resolution appear in nvidia's control panel with the ability to select 60hz, 59hz, 24hz and 23hz using the cp's refresh rate dropdown menu.

- have this custom resolutions appear in nvidia's control panel with ability to use "3. apply the following settings" (i.e. color depth, output color depth, output color format).

- in windows display settings have this custom resolution show as 1920x817 desktop resolution and 920x1080 active signal resolution.

this was a very simple process using intel's igpu, all of the above could be accomplished very easily using cru (or even intel's "graphics command center"), but i just can't get it to work with the nvidia card / drivers.

The only way to add 1920x817 with CRU is to add it as a detailed resolution. Beyond that, the behavior depends on the graphics driver, so I don't know what you can do. The graphics driver normally adds the refresh rates available at the native resolution down to lower resolutions as scaled resolutions if not explicitly defined, but maybe that only happens with certain color formats with NVIDIA. I don't see why the desktop/active signal resolution matters. GPU scaling is supposed to make the active signal resolution stay at the native resolution.

One idea you can try instead of using CRU: search the registry for "NV_Modes" and add 1920x817 there. That controls the list of scaled resolutions that are automatically added by NVIDIA's driver.
