Because we're discussing whether you can notice the flickering of LED lamps. In the film analogy you brought up the issue isn't the "frame rate", which determines whether or not the motion looks jerky, but rather the "flash rate", which determines whether or not you notice the light going on and off. 24 flashes per second at a 50% duty cycle would be very noticeable, which is why in the film days theater projectors used to flash each frame twice.

So I’m curious. I have about 1000 miles on my bolt so a newbie... is the rear view camera display multiplexed? I sense a flicker. Maybe it’s at 30hz refresh? Move head side to side rapidly and it is disturbing...

Use the video when you are backing up, for a wide-angle view, then switch to the mirror.

Why is this so difficult?
