Stating optimum viewing distance as a range rather than as fixed distance is on the rise; possibly because of changes in the profile of the typical HDTV purchaser. Early adopters of HDTV were typically videophiles , [ 29 ] the technically adventurous [ 30 ] and the sports enthusiast [ 31 ] looking to have the ultimate viewing experience.
A 1080p screen will give a very clear account of a 1080p bluray signal, but will give a very blocky version of a PAL widescreen signal. The consequence will be that the optimal viewing distance for an HDTV fed with a standard definition signal will be very much further than a high definition signal.--ML5 14:06, 16 August 2010 (UTC)
For full HDTV resolution, this one minute of arc implies that the TV watcher should sit 3.2 times the height of the screen away (optimal viewing distance). At this distance, the individual pixels cannot be resolved while simultaneously maximizing the viewing area. For more TV resolutions, see "The optimal viewing distance". [3] [4]
A good rule of thumb is that your viewing distance should be about 1.5 to 2.5 times the TV's diagonal measurement. For a 50-inch TV, this means sitting between 75 and 125 inches away.
For example, the optimal viewing distance for a 42 inches (110 cm) Full HD TV (1080p) is 5.5 feet (170 cm). Lechner researched the typical distance between a viewer and their television screen by taking measurements in many American homes. The median distance compiled from all his data came out to 9 feet (2.7 m).
The viewing cone refers to the effective viewing directions of an LCD display, as seen from the eye. This collection of angles resembles a cone. The concept has been introduced as an international standard ISO 13406-2, which defines it as the range of viewing directions that can safely be used for the intended task without "reduced visual performance".

MUSE is a 1125 line system (1035 visible), and is not pulse and sync compatible with the digital 1080 line system used by modern HDTV. Originally, it was a 1125 line, interlaced, 60 Hz, system with a 5:3 [14] (1.66:1) aspect ratio and an optimal viewing distance of roughly 3.3H. In 1989 this was changed to a 16:9 aspect ratio.
