The ideal viewing distance for a 42″ 720p display, for example, is 7.7 feet. If you view it closer than 7.7 feet, most people will be able to see individual pixels, but at distances further than 7.7 feet, you can’t see them. In the case of a 42″ 1080p display, the ideal viewing distance is only 5.5 feet–beyond that, you can’t see the pixels and you can’t really appreciate the full resolution of the display. In other words, it would be virtually impossible to distinguish between a 42″ 720p display and 42″ 1080p at distances of about six feet or more. Given that many people view their televisions from 8-10 feet away (if not even more), you would have to have a 65″ or larger screen to really notice the difference between 720p and 1080p.
