I presume you know this is to avoid Three-Two Pull-down.

I do not, so bear with me if I veer off-track (just coming into video from photography): is the issue that the camera can't read the sensor and refresh the EVF at 120fps, as 120 is not a multiple of 23.97, resulting in the need for a three-two pull down of sorts?

If so, what is the technical limitation/drawback for using instead a refresh rate that is a multiple of the recording frame rate e.g., 119.85?

You are quite correct on all counts.

Cameras with only 60Hz display panels (most have been up till now, and including most laptops - 60Hz also), result in regular judder as occasional frames need duplicating (unless you're shooting/playing back 30fps or 60fps).

I'm not sure why you'd shoot at 23.98fps (or 23.876) these-days? - more generally 24fps works fine and is now the cinema standard. Whichever, as you say they are not perfectly divisible into 120.

Why a 120Hz panel that is capable of variable rate display, cannot run at 48Hz or 96Hz - (for playing 24fps footage smoothly) I'm not sure. My explanations run out here, someone else will need to pick up the baton!
