They are everywhere: big, small, thin, fat, plasma, LCD, Slim, Super Slim, High Definition (HDTV), with or without conversion to digital TV. Result: buy a TV has never been so confused! And the temptations are many, they are more beautiful. After all, many people question it, which should take into account the time to choose a new device for TV?

Well .. are many factors to consider, we give the right verdict. The first point, of course, is the old "want to pay how much?". Each with its each. Worth a lot of research in stores and sites, to check the payment terms, warranty etc.. It is the basic, right?

However, before closing the purchase, the consumer should bear in mind that the best TV is the one with the largest number of HDMI inputs with LCD (cheaper and smaller size), preferably Full HD (much higher resolution of image) with integrated digital TV converter and the size of screen that fits the environment where it is installed. Even complicated, right? So we the few.

Not to deny it: the greatest temptation today is the screen size. But the first thing the consumer needs to assess is where to install the TV and how far it is the dear viewer. Depending on the size of the screen, a greater distance must be respected - if not, there is a risk that the image is not satisfactory.

To calculate the ideal distance, get to the screen height and multiply it by three, teaches Daniel Kawano, an analyst of the products of Panasonic. An example: for a screen of 42 inches (which is 0.67 m tall), the minimum distance would be 2.1 m. Screens over 50 inches (0.70 m in height) should only be installed in environments with more than three square meters.

- The size of the TV will depend on the availability of space. This may be the first factor for a decision, because it influences the quality and display of the image and comfort of vision. When is very close to the screen, you can see the pixels very closely, giving the impression of bad image. The distance an ideal image is more homogeneous - complements José Mendes de Lima Andrade Jr., manager of marketing and products of the Division of Samsung's Consumer Electronics.

And we buy that kind of screen? Plasma and LCD (liquid crystal) still disputing the heart of the consumer, while the second takes advantage of sales. Although many of the traditional models of tube (CRT) for sale, with prices more into account. In this category are the Slim and Super Slim screens, which are nothing more than the last generation of the monitor tube. Moreover, the price of plasma and LCD has fallen every month.

At the top of the chain of consumption are supertelas plasma, some with more than 60 inches - going from 100 inches (or 100). The Panasonic, for example, sells 103 models of "here in Brazil (R $ 229 price mil), and in 2010, will bring a 150. "

Samsung is another of the manufacturers who bet high on the LCD and plasma - but she also believes in survival of the CRT screens. According to Andrade Mendes Jr., the world market consumes more LCD than plasma, a proportion of 80% to 20%. But in terms of technology, you will find quality both in plasma and in LCD, despite the many differences between them (see details on page 12).

Also be evaluating what the consumer thinks essential technologies for your TV. Here come the TVs HDTV (High Definition, or High Definition). Worth note: are not synonyms of digital TV, while HDTV products can "deliver" an image of better quality. It is an important question:

- The digital signal and high-definition TVs come from different sources. The digital TV signal is generated by the stations, which produce images in high definition. To receive them, you need a decoder or a TV with converter built - explains Andrade Mendes Jr. - already a high-definition (HDTV) is a technology that is inside the TV, and is not caused by broadcast. Equipment HDTV has more brightness, better contrast and better resolution of the image.

Ie: you can not have an HDTV and receive a digital signal, but the image will remain in high definition.

From there, the user set up, but now, it will choose a TV with integrated digital TV converter of the electronic card or buy a separate decoder. Today, most manufacturers offer models with embedded converter, a trend that may make life easier for the consumer and remove a picture of the environment.

- You can have a flat screen or TV tube, and still receive the signal from digital TV. Simply install the decoder of the digital signal. But in the use of the HDTV signal will be better because they work with higher resolutions - teaches José Mendes Andrade Jr., from Samsung.
