The resolution of a television is the number of pixels in each
dimension that the television can display natively. You can watch a
media that is not in the television native resolution. However,
watching content in a lower resolution than the television will not
increase the quality of it. Watching 720p content on a 1080p
television will not look better than on a 720p television. Inversely,
you will lose details if you watch a 1080p content on a 720p
television.
The image to the right compares the sizes in term of pixels of the
different resolutions. You can see that the 1080p resolution has
about 4 times the total area of the DVD resolution. Ultra HD (also
known as 4k) is also about four times bigger than 1080p.

Which resolution should I get?
The resolution needed depends on the size and distance of the
television due to the limitation of the human eye.
television due to the limitation of the human eye.
A higher resolution might not be worth it for you. The resolution
that you need depends on three factors: the size of your television,
how close you sit to it and what kind of footage you are watching
(discussed in the next section).
The human eye of a person with a perfect vision (20/20 for North
America or 6/6 in Europe) can only distinguish a detail 1/60 of a
degree apart. This means that at a certain distance, for a specific
size, you cannot see perfectly the full resolution of a television. The
chart to the right plots that distance for the different television sizes
for the 4 main resolutions (480p, 720p, 1080p and Ultra HD).
Using this data, if you are siting 8 feet away from your television,
you will not see a difference between 720p and 1080p for a
television less than 40”. Similarly, the new Ultra HD resolution is
only worth it if you have a television bigger than 60” and sitting
relatively close to it.

A high resolution television is worth nothing if you will only be
watching standard television. The best resolution media is currently
Blu-ray at 1080p, which is even higher than most HD channels or
Netflix. If you do not plan on watching Blu-ray movies, a 720p
resolution is sufficient for your needs.
As of today (2012), there are no widely available sources for Ultra
HD media, even if most movies are currently filmed and displayed in
theater on a Ultra HD resolution.
What is the most common native resolution for a television?
In 2012, most televisions are now in the 1080p native resolution.
Only the lower end models are 720p. The Ultra HD resolution is not
widely available to the public. Models have been shown to CES
2012, but their prices are out of reach of the normal public and they
are not found in common stores.
Conclusion
If you want a television smaller than 40”, stick to 720p only; your
eye will not be able to tell the difference at a distance. The 1080p
resolution is worth it from 40” to 60”. You will only start noticing the
difference with a Ultra HD (4k) resolution above 60”. However, there
are very few Ultra HD televisions available as well as very few media
in the Ultra HD format.
