Choosing an LCD TV: what to look for

Presenting a modern life without a television is still difficult to imagine. And this despite the fact that the Internet is very popular. Meanwhile, television technology also does not stand still.

Once it all started with black and white broadcasting, then it was replaced by color TVs, in fact, which we use until now. Not yet disappeared from the shelves of the usual kineskopnye TVs, although they have long been out of fashion, because they were replaced by modern LCD TVs. A few years ago they were scarce, only rich people could afford to buy them. Today, everything has changed: pleases the abundance of TV models and affordable prices.

Such famous brands as Samsung, LG, Philips, Toshiba, Sharp, etc. are engaged in production of LCD TVs. However, the choice of an LCD TV requires some knowledge, so that in the future you do not have to be disappointed in the purchase. What parameters to pay attention to? Let's try to figure it all out.

Diagonal LCD TV

When you are going to buy such a TV set, be sure to think about where it will stand. This will largely depend on the size of the diagonal screen you need. Today on sale you can find LCD-TVs with a diagonal of 14 inches. Until recently, the biggest was its size of 42 inches, but models with an index of 50 inches have already been released. It is not necessary to chase large-size LCD TVs, if the room where you are going to install it is small. Determine the size can be as follows: while watching your favorite gear, the distance between you and the picture should be about 2.8 meters. The choice of a 32-inch LCD TV is one of the most optimal for apartments, but for a private house in which there is a spacious living room, you can choose a TV with a much larger diagonal.

Screen format

Currently, there are two main formats for the LCD screen. The first - 4: 3 - is used to broadcast ordinary broadcasts. The second - 16: 9 - is used in to watch movies from DVD. If the TV model does not support a wide format, while watching the movie, the picture will be stretched to the full screen, cutting off at the edges. You can buy the TV with the largest format, but at the same time know that in the case of watching ordinary broadcasts, their picture will be somewhat cropped from below and from above.

Resolution

The choice of the LCD TV must necessarily affect this parameter. Television broadcasts are broadcast in 720x576 resolution. But if the use of TV in your case is not limited to viewing analogue transmissions, for example, you are going to watch movies from DVD, digital transmissions, then the resolution should be 1920x1080 pixels.

Contrast and brightness

Both of these indicators are important, since it depends on how high-quality the image on the screen will be. Choosing an lcd-TV will allow you in the future not to regret the purchase made. The contrast of the screen should be at least 800: 1. True, in modern models it is already higher, but it's worth paying attention to. But the brightness should be at least 450 cd / m2. You can learn about these parameters from the technical characteristics of the model.

Response time

In order to choose the right LCD TV, be sure to find out how much is the response time of liquid crystals. The faster it is, the better the quality of the picture. But the response time should not exceed 8 ms.

What to look for more

Of course, the sound. It must be qualitative. And for this, a 2-cavity acoustic system should be built in the TV , the basis of which is four speakers. Also find out which viewing angle in the model in question. It depends on it, what will be the quality of the picture, if you watch TV not in the center, but from the outside. Take the TV safely if its viewing angle is about 178 degrees.

And the last thing - the choice of LCD TV is also in examining the outputs that are available in a particular model. There must be connectors for connecting digital devices. It's about DVI and HDMI. Well, it is mandatory to have standard outputs: SCART, composite and component output, S-Video.
