From that, then, we conclude that somehow 500Hz is important or meaningful?
Movies’ 24Hz is too slow, just watch a horizontal pan. 24Hz is good enough for slow things, but it was chosen that low for cost reasons, not because it’s the limit of perception. US TV’s 60hz interlace isn’t the limit either, which is also shown with horizontal pans. 60hz progressive looks different than 30hz, just watch YouTube or turn on frame interpolation on a modern TV.
The limit of meaningful motion tracking perception might be in the 100-200Hz range. The reason 500Hz is meaningful to gamers is, I think, because of latency rather than frequency. Video systems often have multiple frames of latency, so there actually is a perceptible difference to them between 60Hz and 500Hz.
I don’t know what typical display latency of just browsing files with a monitor these days. I’d guess it’s probably a few frames, and I’d bet we would be able to feel the difference between 3 frames of latency at 144hz and 1 frame of latency at 144hz. I’m also curious if mouse cursor motion blur would make any difference.
