Unless you're sitting closer than two screen diagonals to your TV, it's a scientific fact that even with 20/20 vision you can't tell the difference between SD and HD.
Please reference the NHK's book on their analogue HD technology, Hi-Vision Technology, where they go into the psychovisual research extensively.
