Problem with 4k Dell monitor not recording when set to 1080

I've got a secondary Dell monitor that is native 4K. I've used both SwitchResX and the native display app to make sure that it is set to 1080 and not 4k (3840). What is odd is that when I right mouse in OBS and say "resize output source size", it shows the monitor as 1920x1080 (see attached), but if I don't set my output recording to be 4k (3840), what gets recorded at 1080 is just a quarter of the screen.

I can capture it correctly if I leave the output video set to 3840x2160, but my files is huge and I need to scale it to the 1080 I want.

I was using a 2K monitor previously and did not have the problem.

Thoughts?
