How to choose a TV LED Smart TV with 3D technology
In the last time very often meet people who are interested in how to choose a LED TV and the need to pay special attention to bought the TV brought no disappointments, instead of joy and laughter. In our days, as a rule, every sane person before buying an expensive and long-awaited things is looking for some tips and advice, not sales assistants in stores, and have relatives, friends, work colleagues, acquaintances or more often in the Internet space.
I think that the purchase of LED TV with a Smart TV can be attributed, if not to the category of dear, it is to acquire things in which I would not like to make blunders and that is called «to get into the pool». In this article you will find tips and recommendations about what brands and companies need to pay attention not to discredit their reputation and not to cause resentment and disagreement from supporters and fans. And each of us has its own brands in quality and reliability which we believe…
I shall therefore try to convey to You information about the highlights and technologies that are worth paying attention when choosing LED Smart TV. Of course, progress does not stand still, and the technology now used in TVs follow each other so fast that to navigate in such a space can only be holding «the pulse» and keeping pace with the times. Before how to choose a TV for the home, I recommend to read the technical highlights in deeper.
Well, since I volunteered to tell You about how to choose a LED TV and to do a review on this topic, I will start with defining key words in the article.
LED (Light-emitting diode) — is a new technology that has made a revolution in lighting, which makes it possible to obtain light emission between the cathode and the semiconductor is connected to the anode. Light emission is achieved due to the fact that the electrons when passing through the semiconductor to the cathode interact with the emission of photons. This technology has a clear advantage over its predecessors and does not contain harmful compounds for human health and the environment.
Sales consultants, as a rule, tend to raise the level of store sales without considering the wishes and interests of the buyer. Not to be disappointed from the lack of some necessary features and to choose the right TV without resorting to their help, offer yourself to understand and define a set of features and technologies, which should have Your TV with LED backlight.
Diagonal, case and the settings of the LED TV.
or Diagonal screen size , measured in English inches. This is a standard feature for tablets, digital photo frames, phones and computer monitors. I recommend to read table of the diagonals TV with full calculation of the inches and centimeters in height and width.
To choose the right TV for the home, I recommend to follow the recommendations on the choice of diagonal from the producers themselves. As a rule, all companies believe that a comfortable distance for eyes, and watching TV in General should be no less than 3 of its diagonals.
For example, for comfortable viewing of the flat screen LED TV 40 inch (102 cm) is recommended at a distance of not less than 3 metres. A simple calculation with rounding: 102 * 3 = 306 cm (3 meters). Remember that to choose a good TV with the right diagonal in the store more difficult. Because of the expanse of the trading floor it can appear in sizes smaller than it really is. Therefore, choosing an led TV, make sure that the dimensions of the room ensure a comfortable viewing.
Today TV LED backlight is not only a source of information and a center of video and audio entertainment, but also an integral part of any interior. And probably it would be foolish not to use the elegant forms of design solutions, beautiful and versatile panels that are framed by ultra-thin frame in a home or any other interior. Ultra-modern and stylish design case Supplement manufacturers do not only design, but also technological solutions.
For example, some models of LED TV can automatically adjust the color and brightness of the backlight for the image and the action on the screen. In addition, the creators of the LED TVs sometimes give the model a thin frame, which can change color depending on the viewing angle and brightness. These TVs will easily complement Your interior as the paintings on the wall.
The popular 3D technology used in Smart TV.
Today probably will not find people who do not know or at least heard about the possibility of playing a TV «three-dimensional» image. But if you don't know say that in addition to the width and height of the TV to transmit a visible third dimension — depth.
In our days relevant and popular two technologies with active and passive 3D. As a rule, the choice of TV for many people the question arises, what kind of 3D technology to choose. For starters, let's see how does active and passive 3D technology.
The active 3D technology.
Active technology transmits 3D image for each eye in turn. This is achieved by points that serve as a filter and shut alternately left and right eye which creates the 3D effect. These glasses are called active shutter glasses that need power supply. Typically, the power source is a battery placed between the lenses.
In active 3D technology, each eye may see the picture in full resolution video stream. In other words, if you watch the film in high definition with Full HD, and the eyes perceive and see in Full HD. The disadvantages of active technology can be attributed to a slight darkening of the image and the eye fatigue with prolonged viewing. By the way, the TVs with active 3D technology complete with 2 pairs of glasses due to the high cost in production. But you can buy them separately.
Passive 3D technology.
In passive technology the image is transmitted to the two eyes at the same time, but sent at different angles, and during the passage of the images through lenses of the glasses they are perceived through the eyes of a viewer as a three-dimensional image. Thus alternately each eye receives the intended image that creates the illusion of a 3D effect. Glasses in the passive technology does not need power source.
In passive 3D technology, the image is transmitted with a lower vertical resolution than it actually is. That is, if you watch the film in Full HD (1920 x 1080), the image you'll see in the resolution (1920 x 540), which may not significantly affect the quality of the construction of a 3D image. Glasses is covered with a polarizing film, which in turn will be not a lot to darken the image, but less than active 3D glasses. Moreover, in these glasses the eyes will be tired much less. Passive technology is less expensive to manufacture and typically, these televisions are equipped with 4 pairs of glasses.
To all the above, it only remains to add that feature active 3D is kind but passive in comfort when viewing 3D video to the eyes and optimum cost as a whole. How to choose a 3D TV with active or passive technology, you have to decide for yourself based on Your wishes and possibilities. By the way, keep in mind that glasses from one manufacturer most likely will not work with TVs other.

The functionality of smart TV.
The presence of such features in the LED TV significantly expands its capabilities and transforms it from a source video data in an advanced network media center. To connect to the Internet using a network cable via the LAN interface or wireless Wi-Fi connection, if such is completed with Your chosen model. Otherwise, when you build home wireless connection, you will have to buy a USB Wi-Fi adapter.
Depending on the model and the family of which belongs to TV manufacturers equip and kit them different software and hardware. For example, there may be limited support of services and applications (widgets) built-in browser may be not complete and does not play flash videos, have limitations in the number of simultaneously open Windows, and so on.
in General, before choosing a TV LED Smart TV be sure to define for yourself what opportunities must have Your Smart TV, without paying for options that you won't use it. But in General, Smart TV — it's a home entertainment center that enables you to watch online videos in different genres, watch educational, informational and sports channels, play games and many other interesting things and useful for the whole family.
By the way, the recommended Internet connection speed for standard definition and comfortable viewing online video from a 1 up to 2 Mbit/s, and HD video (high resolution) not less than 10 Mbit/c. If using a wireless connection (Wi-Fi) and watching HD videos, you may experience discomfort in the form of lockups and breaks, but it's also depends on the settings of Your router and subscription from the Internet provider. If observed this behavior of the TV when viewing online videos, you can try to connect Smart TV and the router with a network cable, as the transmission speed on the wire is much higher. Before you run to the store for a patch cord — I recommend to read an article on how crimp network cable LAN at home without any special tools.
As a rule, in Smart TV include the ability devices your local network which allows you to play video from network carriers. It is advisable to Smart TV supported technology DLNA, which will help You to easily integrate the device (computer, phone, tablet…) for sharing media content in real time. Depending on the model and series of your TV, it can be controlled with the keyboard or mouse (described here connect manipulators to the Samsung Smart TV), additional remote control, or tablet and smartphone, gesture and even voice.
Is to say that the term Smart TV to use not all manufacturers, and some represent only their own special sets of functions. As you understand, here already it is necessary to proceed from specific model and series Smart TV. To choose the right TV with Smart and avoid cheating by not bona fide and competent sales consultants You need to determine in advance the model and to obtain for him information, and then to go to the store for purchase.
specifications LED Smart TV.
So I'm not going to paint all the technical characteristics of modern LED TVs, and it is not in the format of this article, and will tell you what you should pay attention to choose good TV. If You opted for Samsung's, be sure to read an article on how to decipher the markings on the Samsung Smart TV.
The modern TV can have a matte screen surface, and glossy. Matte finish is sometimes preferable because the glossy screen in direct contact with bright light can appear dark glare, which can interfere with comfortable viewing. But if the TV will be located in area where no direct light — I recommend to pay attention to the glossy finish, because these screens have better picture quality and can provide higher brightness and vibrant colors. By the way, you can find glossy screens with a special anti-glare coating that significantly minimizes glare under bright lighting.
a Significant part of the LED TVs produced by one of several technologies . Backlit along the edges of the screen (matrix) with white LEDs or with RGB technology groups where the LEDs are arranged in matrix.
- edge-lit — it's not expensive technology in production. The light sources (LEDs) located on the sides of the matrix, and the matrix applied reflective coating, which provides uniform illumination. With the help of this technology you can create a very thin panel, about 3-4 inches.
- The side with dimming — it is a modification of a side backlight in which the LEDs Shine constantly and can disconnect in the area where the lights of the matrix at this point is not needed. This approach allowed us to obtain a more saturated black colour than technology with continuous illumination.
- Local illumination — this technology is more side illumination, but it more accurately highlights individual sections of the matrix, which improves contrast and better color.
- with Local dimming — it is a modification of the previous technology which LEDs may be turned off in that area of the screen where you need it. This approach has made it possible to achieve deep black colors than previous technologies.
To choose a good TV I recommend to pay attention to the screen resolution. The higher the screen resolution the better and more detailed the image on the TV screen. By the way, it is very important to the incoming video signal had no less resolution than the TV screen, otherwise the potential and possibilities will be revealed not until the end.
screen Resolution — is the matrix size of the TV in dots (pixels) horizontally and vertically and is usually written with two digits. For example, 1920 x 1080 pixels. But some modern models can have a matrix of high-resolution HDTV. In HDTV may be a record in the form of one number that represents the number of lines on screen (vertical resolution).
720p (HD) — on a number of technical reasons, the value used is 720 (768). 1366 x 768.
1080p (fullHD) — used in models of primary and secondary level. 1920 x 1080.
2160p (4K ultraHD) — usually used in top models. 3840 x 2160.
p (progressive) — standing letter after the number stands for progressive or progressive scan type. Here the image on the matrix is formed by drawing each line in turn.
i (interlinear) — stands for interlaced. The image is formed on odd lines and then even.
The best image quality provides progressive type progressive.
frame rate (previously called the frequency sweep) is measured in Hertz (Hz). The higher the frame rate — the smoother and less «torn» the image will be. This parameter plays a not unimportant role in the viewing of dynamic scenes. By the way, for comfortable viewing of 3D the minimum value of the frame rate is 120 Hz. However, experts recommend at least 400 Hz.
A few tips for choosing LED TV.
— In our days a very popular digital interface HDMI because able to efficiently transmit both audio and video signal without compression, and in the new versions of some of the interactive features. Actively used for connection to external iPods, home theaters, gaming consoles, computer,… Therefore, it is desirable to have in your TV was at least 2-3 HDMI ports. In one of the publications I have written how to choose a quality HDMI cable.
— Buy a quality surge protector to protect Your TV from power surges in the mains. Modern appliances are very sensitive to them.
— Before purchase, be sure to confirm the lack of TV so-called dead pixels (defective pixels). Because the standards have allowable rate which is calculated by the formula. It's roughly anywhere from 3 to 5 dead pixels which will not be considered a marriage, which means guarantee you can not return (details about the standards and appearance of dead pixels, and how to resolve them see here).
In conclusion, I would like to say a few words about the advantages of LED TV before their fellow men. They have perfect color reproduction, clarity and contrast, which gives the opportunity to evaluate the smallest details of the image. Have a stylish and contemporary design, large viewing angle 178 degree and low power consumption.
