TV resolution guide


Sony Bravia HDTV

The main difference between an HDTV and a standard television is the resolution. A High Definition TV that is displaying high definition content will actually be displaying millions of pixels that come together to create images that are very sharp. Although resolution is one of the main reasons HDTVs display quality is so much better, it is not the only factor that contributes to the picture quality. Resolutions can be slightly confusing for the average consumer. This guide to resolutions will help you understand more clearly.

Almost all HDTVs available today are fixed-pixel displays. They have a native resolution specification that indicates how many pixels are available on the display. The native resolution also indicates the maximum amount of detail you will see on that display. You will mostly come across 720p and 1080p resolutions in the market, especially for widescreen LCD TVs.

Here are the resolutions explained in more detail:

1.       1080p – This is a resolution of 1920×1080 pixels. TV’s like the Samsung 1080p HDTV come with progressive scans and wide screens. General content that come in this resolution are BluRay movies and video games.

2.       1080i – The resolution of this is the same as the 1080p. The difference however is when it comes to progressive scanning. 1080p has progressive scanning that makes it far superior to the 1080i which is only mildly superior to the 720p. This is the resolution that most TV broadcasters are using for high definition, such as CBS, NBC etc.

3.       720p – This is a resolution of 1280×720 pixels. This has fewer pixels but it has progressive scanning; therefore, the quality comes close to that of the 1080i. TV channels like ABC, FOX and ESPNHD use this resolution.

4.       480p – This is the regular resolution of standard definition TVs. They use a resolution of 852×480 pixels. Regular DVDs provide this resolution in output.

Generally, smaller sized HDTVs come with the 720p resolution. Bigger versions, like the Sony Bravia HDTV, come with 1080p resolutions that support full HD. Make your choice based on your content quality needs, and you’ll be happy with your TV.
