Um... just no... that is completely and totally false, I wish people would stop repeating that nonsense... Maybe YOUR eyes suck and you can't see a difference, but put them side-by-side, sitting 6 to 10 feet away, the difference is clear and obvious to most people...
No, it's nothing to do with his eyes sucking, it's to do with the angular resolution that 20/20 vision can pick up. at 8-10 feet, a person with 20/20 vision can not make out better than 1080p on a 60" screen.
I speak from experience...
How sure are you you don't speak from placebo?
