Well, the answer is pretty simple; there is indeed a tipping point after which upping the resolution of video doesn’t make any sense. Our eyes are for example not able to detect resolutions above the 4K(about 8.3 megapixel), but what is the resolution of our eyes?
In short it boils down to the fact that in our field of vision we are able to register 576 megapixels, but our eyes will trim this resolution down to 7 megapixels. Our eyes will make the rest of our field of vision hazy, in this manner our brain can handle the information and won’t overload.
From this point of view 4K is the very limit of what we can perceive normally with the naked eye. Although the difference between 4K and 5K or 10K – 14.7 megapixel or 80 megapixel) – may seem impressive but with our ‘limited’ view we are not able to see the difference with the naked eye.
A higher amount of pixels also means the color spectrum is doubled, which results into a more realistic experience
But although we are not able to register the higher amount of megapixels it also entails a real advantage. This benefit is related to the fact that, despite that thousands of retina cells in our eyeballs capture the visual information (similar to a camera lens, it is our brain that eventually creates one coherent experience of what we see. In this manner a higher amount of megapixels will result in a more realistic experience.
This is due to the fact that a larger amount of pixels also results in a higher number of colors that can represent. In other words, the color spectrum on the screen is doubled and is comes much closer to the way we perceive reality.
