Reviewing Your High Definition Television Options

HD TVs continue to grow and increase their market share. HD Televisions have successfully replaced standard definition TV sets and as the technology for better, thinner HD TV grows, it will be interesting to see where the industry goes. Today there are many manufacturers of HD TVs and there are also a lot of different HD TV types, it can sometimes be hard to know what the main differences are and what features you should be looking for.

HD is defined as high-definition and is used to refer to a higher-resolution image that is displayed using at least 2.1 Million pixels in some instances. There are 3 main HD resolutions that are used today. These resolutions include the 720p HD, 1080i and 1080p or full HD resolution. For HD TVs,720p and 1080p are used for displaying content. HD TVs are fixed-panels television sets, this means that they reproduce content in their native resolution. There is no adjusting of resolution apart from up scaling or down scaling the resolution to fit the HD TV screen. This would mean for example that a 720p HD TV would adjust a 1080i transmitted signal to fit its screen size. This may result in a slight distortion of the image and content but un like standard definition TVs that automatically adjusted the picture, an HD TV will fit the content to its screen size. There are also many types of HD display technologies that are used today, these include plasma, LCD, LED and front and rear projection HD technologies. In terms of screen sizes, HD TVs are the largest TV set that have ever been made available. Where as previous analogue TV sets maxed out at about 55 inch TV screens, some HD TVs are available at up to 150 inches in diagonal size, this does also mean that although the screen size is bigger, the fixed-pixel resolution means there will be minimal benefits of a larger screen.

The real benefits of having HD TV include the multiple connections which include in some instances analogue settings as well as digital connections including HDMI, the universal digital audio and video connection port. There are a number of multimedia systems that can stream or output to HD resolution. Some HD TVs are now also coming with built in internet streaming features as well as wireless display technologies.
