Why are the fastest high-speed cameras so much faster than the faster monitors?

Question

There are commercially available video cameras that can record at 100s of thousands of FPS, and scientific cameras in the millions of FPS. Yet the fastest monitors are around 500fps. Of course, there is much more utility to a fast camera than a fast monitor, but I get the sense that there are also technical restrictions. Why has no one made a 1 million FPS monitor to show off as a tech demo?

Answer 1

Monitors are mostly used for human eyes, we can only perceive a limited framerate, so there is limited use to have a higher framerate.

If you extend the definition of *monitor* a bit, then high framterate single pixel monitors do exist. Multiple of these pixels can be combined to achieve ridiculous speeds for fibre transmissions and each one has a frame rate in the TerraHertz range.
