So if we compare apples to apples, taking the same brand and type of High quality TV sets, if we compare a 30inch with a 60 inch with a 90 inch all with 1080p specs, won't the 90 inch seem intrinsically less clear because the lines of resolution are in theory further apart than the 30inch TV? So back to my initial question of "is there an optimum size screen where the 1080p display will be at its best, and any added increase in screen size will degrade the picture". Another way to ask this question is "what is the optimum size screen to have so that the 1080p display will be at its best?
