High definition is the best available picture for TV viewing; HD comes in 720p and 1080p. 720p and 1080p are both standards of high definition signals.

It may be helpful to know that resolution is just a term that means to show more detail. The number portions of each TV standard refer to the number of vertical lines that is in a single image. Also, note that the initial p stands for progressive, which means the image on the screen creates from the top to the bottom. In addition, the initial i means that the set is interlaced, and that every other pixel line is filled in, usually working on the odd lines first and then returning to the even lines. This process happens so swiftly that our eyes only see the complete image upon the TV screen.

The number of pixels contained per inch of a viewable screen determines its resolution, that being so, then more pixels mean a larger resolution or quality of detailed images. Picture quality displays best at a higher resolution. 1280 pixels X 720 lines (1280x720) and 1920 pixels x 1080 lines (1920x1080) are formats of resolution measurement. Moreover, the vertical and horizontal pixels of an image correspond to the numbers that are used.

A TV display resolution deals with three issues, first there must be a TV station broadcasting signals. The TV must be capable of displaying the broadcasted signal. In addition, unless the set is HDTV ready, it must have a decoding tuner component so signals received in clarity.

HDTV's are able to display resolutions of 720p and 1080p and other formats, which are determined by individual model programming of TV screens bringing better viewing pleasure. As long as the tuner decodes the HD signal, a TV set can display HDTV subject matter. Either a TV can have a built in tuner or a tuner is installed as an external receiver.

These external tuners can be purchased from any dealer that sells consumer electronics. If the signals you prefer are from non-broadcasting stations, you will have to subscribe to your local satellite or cable company for a compatible tuner to your HDTV.

The stir concerning 1080p resolution standard seems to have the advantage of 360 more lines of resolution, which offers a wonderful quality of detail that is several times higher than traditional TV standards of definition. However, its draw back is a native 1080p format is currently not widely available. Although there are so many possibilities of tomorrow's programming and air waves to keep in mind while shopping for the perfect TV screens and their resolution.

Therefore, even though the image is more detailed for 1080p formatting, being able to receive new content is limited in supply. Yet again TV and broadcasting technology are working wonders everyday and there will be new interesting content development in the 1080p format before we realize it.

The choice of 720p or 1080p is best left up to the factor of being able to pick up a native broadcasting signal. As well as your budget and preferences in individual TV screens.
