This is very incorrect. With video, every person can tell the difference between 30hz and 60hz, if they at least know what to look for.
The easiest way to show this is by wiggling your mouse around quickly on a computer screen.
At 30hz - you'll see the mouse teleporting around - hopping from spot to spot, but not moving. For example, if you stare in the middle, and jerk the mouse quickly to the right, you'll see the 4 or 5 spots where it rendered.
With 60hz, you'll see the 9 or 10 spots - and have a stronger illusion of movement.
With 120hz, it might even look as smooth as a real object flying across your screen.
I'm wondering if this is why I find 120hz so jarring. It's almost as if I can't perceive the 'hopping' consciously, but I can subconsciously. It feels like my brain is asking "Wait, how did you get over there?" where "over there" is a fraction of a millimeter. I think maybe there is an uncanny valley for motion.
