Rating TV: how to make the right choice

TV choice - not an easy task for a professional, not to mention ordinary users. Year after year, producers fill all the instruments wide range of functions. Less often the device is used only for watching TV, often it connects to the Internet, video games and gadgets. Technology has allowed many models actually equate to computers. To make the right choice was easier, here is the rating of TV features.

What are the TV: the main types of screens

In order to understand how best to choose a TV, you need to learn the technology, often used in the manufacture of machinery. It should be noted that the rapid development progress leads to the fact that the old model quickly fade into the background, although not all of them are losing relevance. If we study the opinions of experts, which TV is better, we can see that there is a clear solution here because the selection of the best model depends on the purpose for which the device is purchased - for gaming or for watching TV, films.

A popular type of television CRT is a model with a CRT screen, which is used for a cathode ray tube. Previously, the most common model is considered a TV from Sony Trinitronot with a perfectly flat screen. Now, these TVs are in the past because of the large size, lack of opportunity to improve the image quality.

It is interesting!The first television sets that can be installed on a wall, steel plasma screens.

In a separate group can also distinguish laser TVs, which have not received much popularity, but are considered a promising direction. It works by transmitting a laser beam through the RGB filter doubling the frame and the lens on a special chip, which projects the image on a special screen. Rated as the best TV manufacturers with the laser system is considered to be firm Mitsubishi Electric.

How much are plasma TVs and why they were not involved in the ratings

First to replace devices with CRT came plasma screens, which differed a great diagonal - over 32 ", as well as good image quality. Price of plasma TVs is much higher than was the cost of CRT models, but they had a large number of advantages, among which are the following:

• a high resolution;
• more juicy and rich colors;
• an improved depth of the image;
• good brightness - 1000 cd / m²;
• the opportunity to view the screen even in bright light in the room.

By design type plasma consists of two parallel glass plates arranged in the space between which the microcapsules are composed of a mixture of inert gases with phosphor. The image is transferred onto the screen due to the passage of electricity through high-voltage gas mixture where the filler is converted to a plasma state.

Initially, plasma televisions were very expensive both in terms of the high costs of production, and on the amount of energy consumed in the process. Even when the screen is off, if the TV remain involved in the socket, it still consumes energy.

Another negative aspect of plasma screens was considered that because of the constant heavy heating panel is very often screen pixels appear bleached and observed delay residual silhouette, which disappeared after only a time. For these reasons, many companies have stopped making plasma devices. Today in shopping centers can be found less than 1% of plasma. The lack of popularity of such models determines how much it costs a plasma TV. Price appliance varies from 7 to 20 thousand. rubles.

LED-TVs, what it is: the main characteristics of

The most common and popular types of TVs have long considered LED-model or LCD screens. That's LCD (Liquid Crystal Display) release marked the third stage in the development of screen technologies.

Helpful information!LCD, LCD and LED- models - all of these options can be combined into one group, because the LED-TV - is, in fact, there are liquid crystal displays, like LCD, but each of them has a slightly different characteristics and, accordingly, prices.

As the name implies, the LCD panels are composed of liquid crystal lattice, colored filters, protective coating and the light source, whereby the screen and displays an image. The principle of operation of the monitor based on the passage of electrical impulses through a medium consisting of a liquid crystal, which is located between the two electronic boards under constant pressure. Crystals in response to an electric current predictably begin to spin at different angles by altering thus light transmission.

Sami crystals in LCD TVs are not a source of light and color, just depending on their condition, they can completely twist or untwist, changing the light transmission. In order to transmit the image, the crystals must be constantly illuminated. Includes such types of light sources in LCD TV models:

1. The fluorescent lamp. It is a cold cathode flow with white light and is called Cold Cathode Fluorescent Lamp.
2. Cold-plasma lamp. It replaced the fluorescent model, characterized by the presence of external electrodes. Another name - External Electrode Fluorescent Lamp.
3. Neon lights. The technology, which was developed at the turn of the twentieth and twenty-first centuries. It is allowed to make thin and light models of TVs that more accurately convey the color, less heat and consume electricity sparingly.

If you wonder what it is - ICE TV, you need to refer to the interpretation of abbreviations: light-emitting diode, which means "a diode that emits light." This is what distinguishes the LED-display on the LCD. The latest technology allows you to change the brightness of the dot on the different parts of the screen, and makes it possible to get more contrast and better color reproduction.

An important advantage of using diodes considered much smaller size and weight of the TV. The thickness of the current models do not exceed 2-3 cm. Another important fact is considered that the ICE-TV - is a technique that uses minimal electricity.

Useful advice!Studying reviews TV, you can select the Sony LSD TV with 4K resolution and contrast HDR. Models XE93 XE94 and with a diagonal of 55 to 75 inches are used system polnomassivnoy illumination grid matrix, allowing to control color reproduction at the highest level.

The OLED, or organic light-emitting diode, is considered to be the fourth generation in the evolutionary branch of screens when the diodes have been used not only for lighting but also for building telematritsy.

How to choose a TV: What is OLED and QLED technology

Modern technology has allowed instead of liquid crystal lattice used for the display LEDs, because in one pixel can accommodate from one to four units, and each of them will emit blue, green, red and white colors. Due to the presence of such a basic set of colors in the process of mixing can be displayed on the screen millions of different colors, allowing you to make the picture as much as possible detailed and colorful.

In this case, black and greyscale adjustment of presence is performed by muting, and partial or complete shutdown diodes emitting light. The important point is considered to be the fact that the color of each pixel is formed separately, and it happens almost instantly. If a comparison of OLED TVs and LCD models, it should be noted that the main advantage of the first the group believes it is possible to view the picture without distortion from any angle and at different lighting.

It is interesting!LCD TVs with LED backlight LED and LED OLED panel - are two completely different things. The concept of ICE LCD TV means that the instrument uses liquid crystals, but OLED screens consist entirely of organic light emitting diodes.

The main difference between the OLED-model lies in the fact that in this case the sensitive LEDs also act as a light source, eliminating the need for other elements. This fact makes it possible to produce every year more and more thin and light models that make realistic and clear picture, and it allows to build in additional improved TV system sound.

It considered interesting by the fact that OLED system has been developed by LG, designed but is commonly used, and other major manufacturers such as Sony, Philips and Panasonic. Despite the many advantages, advanced technology, and also have some disadvantages, the main ones are:

• the high cost of equipment;
• short life of light-emitting diodes;
• road repairs;
• the fragility of products;
• a small selection of the size of the diagonal.

As for QLED technology, it has been developed by Samsung engineers and used only in TVs of the South Korean manufacturer's other brands such a system is not applicable. QLED principle of operation differs little from the OLED system, and also depends on the action of organic LEDs and unconnected pixels.

Improved color rendition and visual extension of the depth images occur due to quantum dots. In fact, as a result of tests by independent users of televisions they were unable to visually to tell the difference between images and QLED OLED - only an experienced specialist is able to distinguish between these types of screens.

How to pick up the TV for the parameters: the main types of matrices, and the viewing angle

Price, televisions quality as well as the level of contrast, viewing angle and sharpness of the image, dependent on the type of matrix used, which is considered the basic element of each LCD. Initially, a glass matrix represented multilayer flat plates between which layers of different crystals settled. At the turn of the XXI century, the basis of the production of the plates was not glass and more resistant polymer materials. Consider the types of matrices used in the manufacture of television sets, which today are considered major.

IPS-matrix. It has a stylistic contrast of 2000: 1 is used in expensive models, as well as in TV medium-price segment. Televisions with IPS-matrix characterized by a high color transfer and an increased viewing angle as well as better behaved when displaying dynamic scenes. The main disadvantage - long response time, insufficient transmission range of tones of black, high power consumption.

PLS-matrix. It refers to another popular variety that is used in the manufacture of Samsung TVs. It has a high density of working pixels. The advantage is considered to be good, colors and shades. Television games is mainly equipped with a matrix, because the flicker and glare practically do not interfere with the process, and before such screen eyes get tired less.

S-PVA-matrix. It is considered one of the highest quality. Conveys quite deep black color, is characterized by its wide viewing angle, as well as well-behaved in dynamic scenes. List of brands of TVs using a matrix consisting of items such popular manufacturers as Sony, LG, Samsung and Philips.

UV2A-matrix. The technology developed by Sharp, is rarely used in competition. Another firm, employing this technique is considered to Philips. In the manufacture of screens seen improved technology that allows to achieve exceptional contrast ratio, in thereby producing a more intense black color and bright color tones and features a large image volume.

How does the rating of TV viewing angle selection

By comparing the characteristics of television, we can not ignore and such features as the viewing angle. Due to the operating principle underlying the LCD screen technology, it is on this parameter depend on the declared transfer of color, brightness and contrast levels. If your TV model has a low viewing angle, it can not be seen from the side and tilt up or down. This is especially true when setting the fine the TV on a wall, when you can not change its position drastically.

How to choose a TV: the orientation of the size and functionality

Choosing diagonally depending on the size of the room. Other important characteristics: type of matrix, resolution, and additional options.

If you do not comply with the precise parameters of the installation of such a device, you can get the color distortion, as well as cause a glare on the screen, so the device can be secured only through the eyes straight ahead user. Modern TVs have a viewing angle of 90 to 178 degrees.

If you decide which TV is better, it is recommended to give preference to models with a viewing angle of 120˚. It should be noted that due to the development of IPS-matrix could increase the angle up to 178 degrees. But OLED-technology makes it possible to view the image without distorting the angle of 180˚. In the future, manufacturers are planning to increase this number to 360 by the development of flexible and transparent matrix.

The resolution and frequency of the index in the TV updates: what it is

Frequency Index TV updates calculated in hertz and indicates how many times per second, change frame. It is from this figure depends on the brightness and the accuracy of the transmitted TV pictures. Most common TV models have a frequency of 60 Hz, which is considered optimal for human eye perception.

Due to the fact that when shooting the scene, filled with active frame rates, use of modern films such frequency is already beginning to miss. Therefore, updates to TV pays great attention to improving the quality of the dynamic image by increasing the refresh rate to 100-120 and even 200 Hz. This method allowed to move away from the image flicker and improve the image quality of transmission. The larger the screen resolution, the higher the refresh rate used in the manufacture of machinery.

Screen resolution of the TV is one of the most important characteristics that affect the quality of the picture, the LCD monitor display. Most modern screens represent a matrix consisting of a plurality of pixels, and the original density which affects the type of television resolution. Image sharpness thus depends not only on the number and size of pixels, but also from their distance apart.

Useful advice!Comparing the two TVs with the same size diagonals it should be noted that a high-definition screen will be different one which has a smaller pixel size. Thus, the higher the rating will be equipped with a diagonal of 50 inches with a resolution 3840h2160 than the same model with the performance of 1920x1080.

Today highlighted the following main types of formats, screen resolutions:

1. SDTV. It refers to the standard picture from the analog TV. The maximum resolution of up to 720x480 or 720x576 values. The system is considered obsolete and practically no longer used by manufacturers.
2. HD Ready and High-Definition Ready. It observed in the majority of models of modern TV and includes 2 times more pixels than the previous system. Resolution in this case is in the range of 1280x720 megapixels, which allows you to receive high-quality and clear images.
3. Full HD, or HDTV. the system is first started to be used in the production of Sony TV even now in 2007. The number of pixels in this case reaches 1920x1080. The system prevents the distortion of the image, and is characterized by a progressive scan.
4. Ultra HD (4K), it also UHDTV-1. The latest technology used in televisions premium with a high price. The picture has the greatest clarity and reality to deliver color. Resolution is 3840h2160 and update frequency in such models comes to 100 Hz.
5. Ultra HD (8K). To date, the shopping malls there only a few TV models, which differ in such high resolution. The main reasons for this include a very high price on the model, as well as a small amount of available content as such. Therefore widespread 8K TVs in Russia will get no earlier than 10 years.

Interesting information!The advantage of maximum expansion of 4K TV is considered the fact that you can watch movies, even at close range. For example, a TV with a diagonal of 65 inches, which is more than 165 cm, it is permissible to look even from a distance of 2 meters, and with the eyes perceive the image normally.

Diagonal size and other parameters of the TV screens

The rating models mainly goes grading is based on the size of the diagonal, because this is the main characteristic of which is a regular user selects the TV. It is the magnitude of the diagonal and depends on the optimal screen remoteness of the eye that allows you to comfortably view the screen and not be afraid of the sight. In general, the choice depends on the size of these parameters:

• of floor space, in which the screen will be installed;
• TV license;
• the ratio between the vertical and horizontal planes model.

Table, how to choose a TV the size of the room:

Diagonal Size, Inches	Equivalent in centimeters	The distance from the eyes to the television, meters
17	43,18	1
25	63,5	1,5-2
32	81,28	2-2,5
40	101,6	2,5-3
50	127	2,5-3,5
65	165,1	3-4,5
80	203,2	5-6

In the ranking of the best TV for the kitchen are models with a diagonal of 17-25 inches, because in most room all the listening devices in the background when a person prepares or takes food in room. Bedroom usually choose the size of 32-50 inches diagonally, because in this room almost always have the option to postpone the TV 2-2.5 meter from the bed. The large living room is overdue to buy a screen with as large a size that allows room area.

Another thing to consider in determining how far you need to watch TV, the screen resolution is considered. It is important to understand: the smaller the pixels per inch device, the worse it looks at the big picture distance from the screen. In the above table shows the characteristics for televisions with standard extension HD, and televisions Full HD resolution and higher permissible to install at a closer distance, and is connected with what their higher position ratings. As well as these TVs have a lesser impact on the eye.

How does the rating of the appearance of the model, the TV to the Internet: what it is, and whether 3D is needed

In appearance, modern TVs are divided into flat, curved and models with varying screen geometry. The most popular were and remain devices with flat-screen TVs, which can be easily hang on the wall without using additional furniture or stand. Despite this, the powerful companies such as Sony, Samsung and the LG, released on the market model, which differ curved screens.

Interesting information!According to experts, it is really easier on the curved screen to focus the view on several levels because of close to each other the edges of the matrix, which creates the effect of three-dimensional images without any additional adaptations. However, in the opinion of consumers, the effect is achieved only when the scale picture, when shooting close-up image, on the contrary, may be distorted.

The most popular models in the rating are considered curved TVs Samsung UE49KU6500UXUA, UE43KU6650UXUA and UE43KU6510UXUA. The company also produces a unique 78-inch model, which uses a new concept, - Bendable TV with the screen, smoothly varying the angle of bending. A feature of the model is considered as an opportunity to watch a standard flat screen, as well as dish it using the built-in drive.

Smart TV is a set of specific functions, and suggests the possibility of connecting the TV to the Internet by using a Wi-Fi network or LAN cable. High ratings smart TVs have received thanks to the possibility to display entertainment content directly to the screen. It is possible to monitor social networks, listen to music from YouTube, viewing movies and photos.

Another advantage, thanks to which the rating rose smart TVs - is the ability to screen controls using the remote control, not only, but also voice, hand gestures. A fundamentally new stage in the development of Smart TV began to Android TV, allowing you to install the necessary applications and games directly to a TV.

Useful advice!Function smart dialing, built-in TV, significantly increases the cost of the device. There is the possibility of buying a conventional TV model, which is then connected to the external console with the Android system, which makes "smart" virtually any device.

Initially were very popular TVs with built-in 3D using technology alternation of images on the screen for each eye. Due to the fact that every TV viewer is required to have special glasses, as well as due to the small number of TV content available quickly lost relevance, and the use of this function is moved, even in the flagship models.

Which TV is better: "Sony" or "Samsung", an overview of the main producers

The unequivocal answer to the question of which company best TV does not exist, because each manufacturer has its own advantages and disadvantages, so experts recommend when choosing to focus on the required specifications and reviews about the models. If you look at the ratings of brands, the highest positions are occupied by:

• samsung;
• panasonic;
• LG;
• sony;
• Philips.

Japanese company Sony holds the first place in the ranking due to the fact that he had long been on the market and has a good reputation. The company began to produce more CRT screens, and then the LCD-model. With regard to the production of LED-TVs, the Sony manufactures products in relatively inexpensive, and in the premium segment. The main difference of this TV company - perfectly clear and the most realistic picture, attractive design and solid engineering. The advantages should be attributed assembly and high quality, which is held in Slovakia or Malaysia.

It is interesting!The most recognizable line of the company is considered BRAVIA A1, which used high-performance displays with OLED system.

"Sony" TV company is distinguished by the high price and a large selection of sizes - from 32 to 100 ". Negative points include the fact that the Smart TV function only uses paid services.

Manufacturer Samsung is considered the most widespread and popular, because it is a model of this company occupy a leading position in the rankings. According to many reviews, Samsung is the best manufacturer of televisions. This is due to a huge choice of models (24 and 88 inches), as well as with a large spread in prices that can satisfy any user.

In the past year the company has released a line of premium flagship 4K TV with its own QLED system. The assortment is the model with the matrices 60 and 120 Hz, which, in spite of this, different low-contrast and low-definition black. Another drawback is considered to be not the best build quality of devices that runs the factories in Russia.

Other manufacturers that produce the best TVs

LG is also the South Korean representative, which is popular. The main disadvantage can be considered that the perfect image is transmitted only premium model, which is used OLED technology. Despite this, the screens with LCD-matrix and LED-illumination are characterized by high quality and reasonable price. The smart TV companies present a large selection of free applications.

Panasonic - a firm that has long been engaged in production of televisions. Until recently offered a model produced in Japan, and only the latest versions of the devices began to appear in China. Due to the small selection of models firm is losing ground, even though it also produces 4K OLED TVs with high picture quality.

Philips. Despite the fact that the company produces premium models, the most popular is the budget line, which, unlike the products of other companies, have a high image quality. Price of small TVs are much lower than those of competitors. Popularity and adds dynamic lighting Ambilight, which is appreciated by many consumers. In general, Philips TVs are in the category of the ideal price-performance ratio. The downside can be considered a Smart TV work slow and it frequently hangs.

Rating TVs 43 inches and models with a diagonal of 40 and 42 "

In the ranking of 40-inch TVs in the first place can be put of SAMSUNG products - model 40MU6103, which is considered ideal for family viewing. Due to the broad functionality and precise color rendering device has not only excellent picture quality, but also a decent level of brightness. HDR technology makes the image as realistic as possible. Smart Hub allows you to use a variety of applications, and pause live television. Affordable Smart View application allows you to connect to the device gadgets. The price starts from 30 thousand. rub.

In second place in the ranking of TVs of 40 inches is the firm "Sony" model 40RE453, which despite its affordable price - 25-30 thousand. rubles, has an arsenal of useful options and features. Thanks to concise frame of television itself is small in size and low weight, as well as an attractive design. 1920x1080 resolution allows for a high quality picture. Another advantage - the cables exit from the rear side, which allows you to conveniently arrange the outlet for the TV and hide the wires carefully when installing on a wall screen.

TV LG 42 inch is among the most popular models in this segment, because it uses a resolution of Full HD (1920x1080), the vivid, clear and detailed picture. In the production technology used newest system webOS, which provides quick access to entertainment applications.

Built-in universal tuner allows you to receive analog and digital signals. Other useful features include a processor Tru ULTRA HD Engine Pro, and Smart TV technology and Smart Share, allow you to connect to the Internet and other devices. Price - from 20 thousand. rubles.

The best TV with a diagonal of 43 "is considered a model UE43N5000AU company" Samsung ", whose popularity achieved due to optimum balance of price and quality, the presence Edge LED-illumination and resolution Full HD. Better image quality with respect to other models with similar resolution, is provided by Ultra Clean View technology, which reduces the possibility of noise and interference. Other advantages:

• The "picture in picture";
• presence light sensor;
• a standard set of connectors;
• the ability to connect home theater;
• small power consumption - 105 W;
• price - 25,000 rubles.

Rating televisions 55 inches and other large models

If we consider the question, what brand is better TV with a diagonal measurement of 55 ", there is the advantage belongs to the company SONY, most of the models are produced in Slovakia. The first model of "Sony" size of 140 cm, which is equivalent to a diagonal of 55 ", is the KD-55XE8096, which is considered the most cheap with available features.

High resolution 4K UHD with support for HDR and IPS-matrix gives an opportunity to get a beautiful, realistic image. Smart TV function works on the Android platform and has a stable job fast. TV, thanks to the built-in features Wi-Fi, Bluetooth and Miracast, has access to the Internet, as well as built-in memory of 16 GB. The average price of the TV to the Internet is at the level of 62 thousand. rubles.

Slightly better in quality second model SONY - KD-55XE9005, which also has a resolution of 4K and supports HDR. The main difference from the previous version - the presence of the backlight Direct LED, the light is evenly distributed over the entire area of ​​the screen, and light sensor. Another advantage of the model - three built-in TV-tuner, which are used to view multiple channels simultaneously using the "Picture in Picture" function. Price models - from 132 thousand. rubles.

If we talk about the big screen, here a strong lead Samsung TVs. Especially popular model, released last year, - UE78KU6500U. The screen has a curved shape and a very small frame, which almost corresponds to the size of the screen. The width of the model - 78 ", which is equal to 198 cm.

The TV uses a cutting-edge feature Wide Colour Enhancer, regulating the coverage of the color expansion, allows you to enjoy a large-scale detailed picture. The increased image sharpness available through local dimming UHD Dimming technology which further improves color reproduction. Other features:

• format - 16: 9;
• matrix type - blue LED;
• resolution - 3840h2160 pixels.

TV, thanks to Dolby Digital Plus technology transmits good sound, has a smart function, Internet access, built-in tuners and energy efficient. Such an extensive set of functions and affects how much TV "Samsung". Prices in shops will start from 280 thousand. rubles.

In addition to these companies, there are ratings and other manufacturers, such as Sharp, Toshiba, Thomson, BBK, and many others. However, a small selection of models with different characteristics do not allow them to overtake already won the popularity of the company, who are constantly working to improve the quality and additional set functions. Keep in mind that every year the rating of the best models vary, so before buying a better review the existing trend.
