Any purchase is always fun.
Especially if it's buying a 3D TV. A wide range of models and a lot of functions makes the choice difficult.
In fact, every modern TV has a standard set of functions and capabilities.
Having studied the most important parameters, you can make the right decision.
Before buying a TV, determine how muchYou are ready to spend money. Do not buy the latest model, even if money is allowed. The prices for novelties are always overestimated. Compare the cost of the same TV model in different stores. As a rule, prices vary, this can be saved.
Decide on the brand and design of the TV. If the brand is not important, then choose in appearance. Models with a thin frame look most spectacular. The TVs with LED backlighting have a small panel thickness, but the price is higher than with a conventional CRT backlight. Sometimes the TV brand makes a difference. If in your city there are service centers of any firm, then it makes sense to buy a model of one of these firms. Under warranty TV can be carried to the service center, bypassing the store. But where the question is resolved quickly, it is difficult to guess. However, this fact can be taken into account when choosing.
The cost of a 3D TV depends to a large extent on theScreen size. The larger the diagonal, the higher the price. For a home theater it is advisable to choose a TV with a large diagonal, but to follow the principle "the more, the better" is not always correct. It is necessary to take into account the distance between the screen and the viewer. The optimal distance for watching TV is 3-4 times the diagonal. For example, if the screen size is 82 cm, the distance should be between 2.5 and 3.5 meters. This must be taken into account, because the number of dots or pixels on the TV does not change as the diagonal increases. The size of the point itself increases, and at a short distance the image will be fuzzy and blurred.
Screen resolution refers to a very importantCharacteristics of the TV. The image quality directly depends on this parameter. To play a high-definition picture, the screen resolution must be Full HD 1920 by 1080 pixels. All 3D-TVs have this permission.
3D-technology makes the image volumetric andCreates an effect of presence. TVs use shutter and polarization 3D technology. On the type of system depends on what glasses are needed to watch movies - active or passive. Active glasses work on battery, passive battery is not needed. Glasses in active glasses play the role of closures and constantly flicker with a high frequency, which can create a small discomfort for the eyes. In passive glasses this is not, they have a different working principle and the price is several times smaller. Advantages of active glasses are high color rendering and no loss in image resolution. In a set with polarized TVs, 4 pairs of passive glasses are usually delivered, and with TVs of shutter technology there are 2 pairs of active glasses, or there are none at all. If you focus on the price, then TVs with passive glasses are cheaper. When buying a TV with shutter 3D technology, be prepared for additional spending on active glasses. Which system is better, hard to say, always has its advantages and disadvantages. Everyone can choose what suits him best.
The DVB-T2 digital tuner provides a high quality digital television signal for a normal antenna. When buying, please note whether there is a given tuner on the TV.
One of the new and useful features relates toSmart TV, or "smart TV." Smart TV allows you to connect your TV to your home network, computer and other devices. Through the built-in browser you can use the Internet, as on a computer. The TV becomes a media center. You can watch videos on YouTub, use Skype, connect a keyboard and a mouse.
Wireless technology allows Wi-FiConnect to the home network without using wires. Please note that not all TVs come with a built-in Wi-Fi adapter. Before buying, determine the need for this option, whether you have a home network and a Wi-Fi router. TVs with a Wi-Fi-module are more expensive.
The frequency of the picture update affects the qualityImages in motion. To prevent moving objects from being smeared, the frequency must be at least 200 Hz. This is especially noticeable on sports channels and when watching movies with a quick change of actions. For not very demanding users, this is not critical. In the latest models of TVs the refresh rate is 400, 800 Hz and higher.
Modern audio and video equipment is not onlyA means for entertainment and recreation, but also an interior decoration. Pay special attention to the fact that the TV harmoniously fits into the surrounding situation.
