HD TV Features

Technological advances are occurring within the television industry day by day. It seems that we often have to compare different brand names of television to ensure the best quality possible. One of the best 'upgrades' ever done in the world of technology is the creation of HD TV. But what is an HD TV and where can you get free HD televisions?

HD stands for 'High Definition' and it simply means that a television has a higher resolution than a normal television – meaning more clarity and more details. The normal encoding system (PAL) which is typically used for analog and digital televisions, has a resolution of 720 x 576 pixels. This system is also called a standard definition (SD) system. There are two main types of HD TV: those with 1280 x 720 pixels and 1920 x 1080 pixels which means that these two types produce two times and five times more details respectively. HD TV produces resolution with extraordinary quality. An HD-ready logo implicates that a particular television produces HD images in an appropriate manner. This is actually an official logo that lets us know that a certain television meet the requirements of being an HD TV. For instance, a television has to have a minimum of 720 pixels in widescreen format to be coined as HD TV. There are also flat screen TVs with a screen resolution of 1920 x 1080. These flat screen TVs are colloquially termed Full HD TVs. This is not an official logo but more and more manufacturers make use of this term to specify a certain TV. There is also an official logo for televisions utilizing the highest form of HD-format. It is called HD-ready 1080p. It is an expanded form of the 'HD-ready' logo. This type of format also has its own set of requirements. Nowadays, almost every Full HD TV meets the requirements of the mentioned format. There are also televisions which makes use of 1080p format but can also adjust to a lower resolution format.

It doesn't matter if you have an LCD or LCD-LED television as long as the television you purchased has an HD-ready or Full HD logo on it. Some might question which one performs the best or has the best quality – the 720p (first type) or the 1080i (second type). If you're more of a sports fan or the programs you typically watch show a lot of motion and speed, you can choose for the 720p. Meanwhile, the 1080i is more suitable for documentaries and talk shows.
