High definition television is the highest form of digital television. It has a 16:9 aspect ratio, which is the same as a movie theater screen. This is possibly HD's biggest selling point. The other is the resolution. High definition is the best available picture on a television. It comes in three different flavors: 720p, 1080i and 1080p.
What do 720p, 1080i and 1080p mean? High definition programs are encoded with a type of resolution: 720p, 1080i or 1080p. The number stands for the amount of lines embedded within the signal. The letter describes the type of scan the television uses to display the picture. The 'i' means interlaced and the 'p' means progressive. Why does the amount of lines matter? The number of lines on a television is important because it allows for greater detail in the image. This is a similar concept to digital photos and how dpi determines print quality. The type of televisions all of us grew up watching had 480 visible lines on the screen. By doubling the amount of lines in combination with the type of scan, HD essentially doubles the quality of picture. Does it matter if the resolution is interlaced or progressive? The type of scan is arguable considering the amount of lines for each HD format. Progressive scan is a better type of scan because it doubles the amount of times the TV displays the image per one second in comparison to interlaced. Still, the difference between 720p and 1080i is so minimal that is isn't an issue at all. While 1080p is better than 720p and 1080i, very few programs are made in this resolution so it really isn't a factor right now…and, it might never be.

Is a full high definition television better than High definition ready television?
The terms used in HD television are confusing and inconsistent.The one term that is consistent is "HD ready". It means that if the television receives an HD signal, it will display it. However, it has nothing to do with the resolution of the screen itself. There have been HD ready televisions marketed that had a screen resolution of 480 lines which is the resolution of standard definition in North America. Whatever HD signal that television received, the end result can never be any better than standard definition. Such marketing is misleading and dishonest."Full HD" normally indicates that the television has a native resolution of 1920 x 1080. This is the highest HD standard being broadcast today and such a television is capable of retaining the full quality of the incoming signal. However, the term is sometimes used to describe other features of the television. The only way to guarantee that the television is full HD resolution is to examine the specification. If the spec says that the screen resolution is 1920 x 1080, it's full HD. If the spec says it can display a 1920 x 1080 signal, this does not mean the screen itself is that resolution.Despite the numbers, the best way to select a television is to look at it. If the image looks good, the detailed specification is not important. It is important to do the research before going to the shops. Having information will help to survive the misleading and uninformed salesmen that are found in so many stores. By no means all salesmen are of this standard - many are honest, competent and informed. Your job is to know enough to tell them apart.
Which passive 3D TVs are full HD 1080p?
Passive 3D televisions are normally 1080 line. However, the image is split into left and right images so the effective resolution becomes half the full HD resolution, namely 540 line. So although they can claim to be full HD, they have a total of 1080 lines, the viewer sees only half the full resolution.
