Want to rotate image 90 degrees - Can't - Resolution

I have one of my cams (2831) setup and decided I'd like to try rotating the image 90 degrees. After hitting Save in the cam UI, an error message appears saying "Current resolution doesn't support this function".

Is there a resolution setting somewhere I need to adjust to make this possible or is it really just trying to tell me that this isn't possible on the camera at all?

That's not a question I remember being asked on the forum previously.
So -
I'd guess you'd figure out what resolution setting would support the 90Deg rotation by changing the various resolution choices and trying the rotate function.

Had to step it down all the way to 1920x1080 to be able to get it to allow the 90 degree rotation. So from 8MP to 2MP.
