That chart is based on SMPTE 30. It sets the line at 60 pixels per degree before recommending a higher resolution. Now it's true that 20/20 vision is based on 30 cycles per degree resolution to be able to read text. But human visual acuity easily goes up to 40 or 50 cycles per degree and beyond. The point is not from what distance you can still make out the individual pixels, but from where you see a smooth life like picture. |
I doubt those results. I have played 720p and 1080p with my 40" TV from distance of around 7 feet and difference is very minimal. Actually, there have been a lot of people who have thought 720p is 1080p and 1080p is 720p. I'm sure that 99% of the people won't see any difference at all between 4K and 1080p on less than 40" screen at view distances more than 6 feet when most can't even see the difference between 720p and 1080p on same screen. Even for those 1% difference is extremely minimal.
Anyway, even 1080p is overhyped and 4K even more so. Sure, it might be the "future" but it will never be a must-have. 1080p is just fine even 10 years from now.
