The receptors in your eyes are slow ass chemical ones, that can detect, under optimal conditions 13ms pulses. That is around 75Hz. Anything faster and you will not see it.
20+ years ago, I bought a vacuum tube monitor that could adjust the refresh rate from 60hz to 144 hz. I was able to see the difference in refresh from 60hz to 120hz. I could tell you if the monitor were running at 80hz, 100 hz, 60 hz, abd be EXACTLY correct every time. I would usually guess correctly between 120hz and 144 hz, but my ability to ascertain was not as solid as between 60hz and 120hz.
Long story short, do all the math and logic that you want but my brain notices a difference where your math and logic says it shouldn't. Now, I am a lover of math and logic, but experience has taught me that in theory, theory and reality match, in reality, they do not. Theory and logic ALWAYS lose out to reality.
But, this makes me wonder. Why do you appear to be resisting this change? Just because it doesn't suit you? Do higher refresh rates and resolutions hurt you in some way? Or are you just being a curmudgeonly old bastard?
I do not object if you buy low res and low frequency monitors. I do not object that they are available. Why do you object at high res and high freq?
