From your video, the human eye only has 6 million cones and cant perceive all of the 8 million pixels of a 4k image. That's still alot more than the 2 million pixels of a 1080p image. You can perceive enough information to tell the difference between the two formats.
Anyone who actually cares about image quality can tell the difference between 4k and 1080p, if you cant afford 4k then it's cool to try and argue that there's no difference at all.
That was a post completely irrelevant to the topic of this garbage ass thread.
By your garbage logic, the human eye shouldn't be able to perceive the difference in the pro and the 1X, when in real life the difference is very noticeable.
