Understanding Hi-Def TV

If you go in the first TV-Shop for your high-definition, you can have all confused by the many, many different specifications you'll see. While a full description of product information on the book would be, it is possible not only the difference between plasma and LCD in just a few minutes later.

Start with this difference. The three basic types of HDTVs today are LCD TV, plasma TV and DLP TV,modern version of the old projection TV. An LCD and DLP are backlit, making it difficult for light colors black screen, plasma televisions in a slightly different lighting, so that blacks have a very realistic, but tend to be a bit 'more expensive and much more tender . A DLP TV usually looks good, and the lighting is easy to change that for anyone, was perhaps the longest lasting of all the other HD TV is that, and if you have a projectorrather than a closed system, you can scale the image to fit your space – an advantage. But LCD TVs may also have the worst image of the three areas.

The next dimension. All HDTVs have a wider aspect ratio, so that instead of the TV screen almost square, the traditional form, have coined a movie screen, often called 16:9. This does not change, so do not worry. (For comparison, a regular TV aspect ratio of 4:3, although this is notnever mentioned -). Def screens measured on the diagonal, so that as high as a conventional TV with a TV the same list of small screen size and is unlikely to seamlessly in the same room. Keep this in mind.

The resolution is more complicated. Traditional TV and 480i resolution. This means that the image displayed on the screen in 480 rows, the "i" stands for "interlaced," meaning that the odd lines are displayed, then the even lines, with about one-sixtieth ofsecond ad before you turn it on. Our vision tricks to think it is a flat screen. Rare 480p TVs have all the lines shown at once, and you will notice a much better picture.

On HD TVs, on the other hand, from 720p set, most are just around 1080p. Look at this, you want to make sure that all video devices, as well as boxes and Blu-ray compatible cable with this resolution. A mismatch is the reason a number of HD TV can notas good as it should be. In addition, more is not better if you can get better than 1080p, if the devices do not match (and most do not), you are not a good image.

All standard HD TVs have covered the product information in the following areas. Test your TV and peripheral devices matched as closely as possible, and experience the best picture quality.

* 1080 lines with 1920 vertical pixels, aspect ratio of 16:9 and 60i, 30p, 24p or display (time-between updated)
* 720 lines with 1280 vertical pixels, aspect ratio of 16:9 and 60i, 30p, 24p or display
* 480 lines with 704 vertical pixels, 16:9 or 4:3, with 60p, 60i, 30p, 24p or display

When choosing an HDTV, more lines tend to be better, better is 16:9, and a number more p makes for better viewing. While HDTV is compatible with traditional broadcasting, it is wise to invest in high-definition channels, the picture is very, verybetter with an HD TV.
