What can a modern TV do? Expert recommendations for choosing a TV

The TV production industry is one of the most dynamically developing. It has always been this way: once upon a time the world imperceptibly moved from black and white screens to color ones.

Then - from huge CRT screens to miniature “flat” ones.

What are the main trends of today? How to choose a TV that will not become morally and technically obsolete within a reasonable time? There are, of course, purely subjective criteria. Well, for example. What diagonal should I choose for my TV? It all depends on the preferences of the buyer.

Where to place the device, how to choose a bracket for the TV, or how to most conveniently place the TV on the stand? All these questions, of course, are relevant, but each owner will have to solve them individually. Because, as you know, there is no comrade’s taste and color. We will try to consider the technological aspect of purchasing equipment.

TV: plasma, LCD or LED?

The most modern technologies for manufacturing displays that are used by the electronics industry in the TV segment are LCD (their operating principle is based on the physics of liquid crystals), LED (in addition to liquid crystals, they also use special light-emitting diodes) and plasma (they work using gas-discharge elements ). Displays based on these three technologies are gradually replacing traditional CRTs (cathode ray tubes). How to choose a TV based on the pros and cons of each?

LCD and LED displays are united primarily by compactness (“flat screen”). Also, these technologies are characterized by lower energy consumption compared to CRT monitors. There are ongoing discussions among experts about image quality. Some experts emphasize that LCD TVs are characterized by a fairly low level of contrast, and there is a distortion effect when viewing the screen from different angles. LED devices for the most part do not have such disadvantages.

LED TVs are divided into two subsegments, depending on the type of backlight. The most common today are Direct and Edge. The first type of backlight is characterized by the location of diodes directly under the monitor matrix. Thanks to this solution, the picture turns out clear, bright and rich. But such devices are much more expensive than analogues that use Edge technology, in which the LEDs are located not under the matrix, but along its perimeter. In addition to being cheap, this technique has another advantage - small thickness (no more than three centimeters).

Among the disadvantages of LCD TVs (especially for outdated models) is the presence of a “pause” between the signal being sent to the screen and the actual projection of the image. This interval is called the "matrix response". When thinking about how to choose an LCD TV, you should keep this in mind. The technology used in the screens of LCD devices involves the following feature: when current is applied to the matrix, the pixels begin to glow (produce a programmed color shade) not immediately, but after a certain period of time. The smaller it is, the higher the image quality, especially in dynamics (when there is intense movement of the video sequence).

Plasma TVs are devices that use gas bulbs instead of liquid crystals and LEDs. Such devices are characterized by very high brightness and contrast. In terms of image quality, “plasma”, as many experts believe, is significantly superior to LED and LCD TVs. However, it has a number of significant disadvantages. First of all, this is high energy consumption. In addition, the peculiarities of the technology are such that screen “pixels” fade over time. In addition, the price of such devices is usually higher than that of LED and LCD analogues with similar functions.

“And which TV is better to choose?” - the reader may ask. There is no clear answer. The buyer has to decide what is more important: picture quality, power consumption or shelf life of the device.

Projection TV: mini-cinema in the room

Among the innovative types of TVs are projection ones. They are designed on the principle of a cinema, when a color image is projected on a white canvas. Their main advantage is their low price. Experts note, however, that such devices have the problem mentioned above related to pixel burnout. In addition, the image seems to many users to be insufficiently bright and inconsistent when viewed from different angles.

Laser TV: an ideal option at an immodest price

Another innovative type of TV is laser. Many experts consider them ideal in terms of picture quality and service life. There are no problems with pixel burnout, their power consumption is low. However, the price is much higher than for LCD, LED, plasma and projection TVs.

Does brand matter?

Having decided on the criteria for choosing a modern TV in terms of display manufacturing technologies, the buyer will certainly pay attention to who made the TV. There is a version that almost all household appliances are assembled according to the same principles, similar or completely identical technologies. Sometimes devices differ only in the brand logo on the panel. There are also opponents of this thesis, who believe that the quality of equipment still greatly depends on the manufacturer. To confirm this, they provide sales figures that clearly show that there are leaders and outsiders in the market. Which suggests that the quality of equipment produced by both differs.

Which TV to choose - Japanese, Korean, European or Russian? This question is answered, of course, by the buyer himself. But it is, of course, worth considering the specifics of the market positioning of leading brands. This will help form an idea of ​​the consistency and competitiveness of the manufacturer and give some clue as to which brand of TV to choose.

Comparison with SAMSUNG

In recent years, the Korean brand has been the leader in the Russian market in terms of TV sales (its share accounts for about 30% of revenue in the segment).

The specificity of Samsung is that a significant part of its products is produced here, in Russia, at an electrical plant in the Kaluga region. It is quite possible that some TV buyers, when thinking about how to choose a TV for their home, first of all pay attention to the country of origin of the equipment. The fact that the device was released in Russia may please patriotic citizens.

It is significant that in 2012, when many of the largest market players lost turnover, Samsung sales in Russia increased by 12%. Marketers note that the brand pursues a competent marketing policy and also pays great attention to the constant updating of the line of TV models. Some experts also especially emphasize the fact that the Koreans played one of the most important roles in promoting SmartTV technology on the Russian market, which is now rapidly gaining popularity.

PHILIPS is breathing down your neck

The Dutch brand Philips is the second largest brand in Russia after Samsung (about 20% of the market). Just like the Koreans, the European company opened its own production facilities in the Russian Federation - in Kaliningrad and in the village of Shushary (Leningrad Region).

Experts praise Philips for its wide range of models in a wide range of price segments. Thus, everyone has the opportunity to buy a good and at the same time inexpensive TV. If a buyer is thinking about how to choose the diagonal of a TV, and at the same time he is interested in the reasonable cost of the device, he may need to pay attention to the offers from the Dutch.

By the way, one of the samples of their technology earned the title of best 3D TV in Europe in 2011-2012. It is worth noting, however, that the brand’s global marketing strategy was not very successful. Due to large losses, the concern sold the bulk of the shares of TPV Technology (Hong Kong).

TOSHIBA: Honorable Bronze

The share of the Japanese brand TOSHIBA in Russia is about 12%. Experts explain the company's success by the fact that the TVs it produces are, as a rule, very easy to learn and take very little time to set up. Just like Philips, the company is ready to offer the Russian buyer a large selection of models in a wide price range.

SONY: almost a pedestal

In fourth place in Russia is the Japanese brand SONY (about 10% of the market). Experts explain the popularity of the brand in the Russian Federation by the fact that the company has proven itself well in the first years of its appearance on the Russian market. Until now, the SONY brand is associated among the residents of our country with high quality. True, as in the case of Philips, the situation at the global level for the Japanese company is not very good: over the past few years, as analysts note, the company has been steadily incurring losses.

Other famous brands

There are other major players in the TV sales segment. Many Russians decide to choose an LG TV - this brand has about 9% market share in the Russian Federation.

Panasonic also has a significant position, traditionally offering Russians interesting innovative solutions.

Top 10 most important options

Once we have decided on the display technology and brand, the question will arise: “How to choose a TV based on the need for certain functions?” Let's look at the 10 most important criteria for modern TV that you can focus on when purchasing a device in a store. It is worth noting that they are universal for all types of devices popular today - LCD, LED, plasma. So, our task is to choose a TV according to the parameters that are most significant for the modern buyer.

1. Matrix resolution

There are two main formats - HD Ready (considered a lower level) and Full HD (more innovative). Experts note that there is no point in choosing a matrix with Full HD (a TV that supports it usually costs more) if the device screen is small - it will still be problematic to see small details. To see how good the picture is in HD modes, it makes sense to choose a 32-inch TV at a minimum.

2. Supports HDTV and UDTV standards

HDTV stands for High Definition Television. This is an innovative standard that allows you to achieve very high image quality by making the most of the high resolution of the device in combination with digital data transmission technologies. Also, the HDTV standard allows you to achieve the highest sound quality (due to multi-channel playback of the audio stream). The typical HDTV screen format is 16x9. As the technology continued to improve, the UDTV standard emerged, which stands for “ultra-high-definition television.”

3. Screen resolution

Resolution is a parameter that determines the number of dots (pixels) per unit area. The more there are, the brighter, clearer, and more saturated the picture. Resolution is usually specified in vertical units (for example, 1080 p or 720 p, where p is pixels), but almost as often the number of dots that form their image is indicated horizontally. For example: resolution 1920x1080. TVs that support the Full HD standard typically have a resolution of at least 1080p.

4. Contrast

The higher the contrast of the device, the higher the image quality. This parameter is the ratio of the maximum brightness level of the monitor to the minimum. Contrast is one of the most important characteristics for LCD and plasma TVs.

5. Sound power

The higher this parameter, the better the sound quality. Even if the nominal volume level of the TV is low, with significant power we have less distortion of the sound stream. That is, the question is not the volume of the speakers (including external ones that can be connected), but the level of technology of the device’s sound subsystem.

6. Availability of multimedia connectors: HDMI, SCART, VGA D-sub, USB

If your TV has an HDMI connector, this will significantly expand the functionality of the device. This technology allows you to transmit video and audio signals in digital format. Using HDMI technology, you can, for example, synchronize a TV picture and a computer monitor image (or mobile devices).

SCART is an innovative interface, which is a patch connector compatible with a large number of multimedia standards - S-Video, composite video, stereo audio, etc. Using the SCART connector, you can not only send a signal to the TV, but also receive a digital data stream from the device itself (for example, to record a video broadcast on a tape recorder or computer).

This interface is designed to transmit video signals from the TV to other devices with minimal distortion. The VGA standard was first used in personal computers. Now it can be used to exchange information between many types of devices.

Another typically “computer” interface that has been introduced into the television industry is USB. Using this connector, you can connect flash drives, other storage devices, and a large number of other devices to the TV.

7. 3D support

One of the most pronounced trends in the modern TV industry is 3D technology. They allow you to see the picture shown on the screen in three-dimensional projection, that is, in a form as close as possible to the real one. Watching 3D movies and clips fascinates people a lot. Many people constantly think about questions like this: they say, I have a 3D TV. How to choose a good movie to watch tonight? And they forget about important pressing matters.

8.SmartTV technology support

SmartTV is an attempt to “hybridize” TV and computer. If the TV supports this technology, it thereby turns into a kind of PC (or, with a certain platform architecture, into a “large” smartphone into which various applications can be downloaded).

We noted above that the popularization of SmatTV technology in Russia is largely due to the marketing of the Korean company SAMSUNG. Therefore, if the question is “how to choose a smart TV,” then perhaps it makes sense to pay attention first of all to the offers from this Asian brand. It can be assumed that, occupying about 40% of sales of TVs with SmartTV support, SAMSUNG is able to supply Russian users with a wider range of opportunities - in particular, in terms of the number of specialized TV applications and their adaptability for the Russian market.

9. “Picture in Picture”

Before you finally choose a TV, having studied the specifics of displays, brand positions and analyzed the necessary options, you should pay attention to a number of additional functions that are quite useful in many cases. Among these is support for “picture-in-picture” technology, in which not one, but two or more images from different sources can be displayed on the screen. This allows you to watch several channels at the same time (or, for example, a certain program and a DVD movie).

10. Child protection

Another useful feature is childproofing the TV. Before asking the question of how to choose the size of a TV, it makes sense to think about whether it might turn out that something that is not entirely compatible with the age of the audience will be shown on the big screen? And if this is the case, perhaps you should choose a device that allows you to limit the display of unwanted images (to children, for example)?

Moreover, many modern TVs have such options. Using a special code (or a sequence of actions performed by the user), access to certain channels or functions of the device can be prohibited. So, for example, you can block channels in the “adult” category. It is important not only how to choose the right TV, but also how to watch it correctly, from the point of view of how the TV picture is perceived by different categories of viewers.

Choosing a TV antenna

Despite the dominance of digital technologies that allow you to watch TV programs in unprecedented video and sound quality, the use of traditional TV antennas is still relevant.

For residents of dachas and country houses, solving the problem of installing a high-quality device for receiving a signal is much more important than the question of how to choose a good TV. What parameters should be taken into account in order for the channels to be caught well? Let's look at the characteristics that apply to devices for receiving signals of any type. Knowledge of the following features may be useful to those who are interested in how to choose an indoor antenna for a TV.

1. Gain

The higher it is, the greater the chance of “catching” the signal, and the clearer the image will be. This parameter should not be confused with any values ​​for a device called an "antenna amplifier". In this case we are talking about ordinary (“passive”) indoor equipment. Gain is measured in decibels. Experts consider a value of 3 dB to be a good indicator.

2. Directional pattern

Measured in degrees. This characteristic, as experts believe, is one of the defining characteristics for indoor antennas. The range of the most common values ​​is 40-80 degrees.

3. Anti-interference factor

Measured in decibels. The higher the coefficient, the higher quality the television picture will be. This parameter shows how big the difference is in signal reception by different parts of the device.

How to properly install an outdoor antenna?

Having decided how to choose an antenna for a TV, from the point of view of key technical parameters, we systematically approach the next question: “Where to place the device?” If possible, take the equipment outside - this increases the likelihood of “catch” more TV channels than when using an indoor antenna. Not to mention the picture quality - it is almost guaranteed to be higher.

First, if possible, there should be a direct line of sight between the device and the TV tower.

Secondly, the antenna should be clearly fixed. It should not turn around or sway too much from the wind.

Thirdly, the cable connecting the equipment and the TV must have a sufficiently large cross-section (the best option is 8 millimeters). In this case, the signal from the device to the TV will pass with minimal distortion.

Fourthly, if there is an amplifier, you need to place it on the antenna itself, and not in the room. Only in this case its functionality will be fully utilized.

No matter how functional and technologically advanced modern digital TVs are, “how to choose a high-quality TV antenna” is a fairly pressing question. We hope you received a comprehensive answer to this.

A pleasant decision to buy new equipment for your home always entails a number of questions, without answers to which a trip to the store will turn from a successful event into a complete disappointment. Which TV to choose? What should you pay attention to first? Which brand should you prefer? In order to choose a TV according to its parameters, you need to have a general idea about them and select several that seem most significant. As a rule, selection begins with the manufacturer. And if the consumer is not a supporter of experiments, then he limits the brand names to six: Samsung, Philips, Panasonic, Sony, LG, Toshiba.

How to choose the TV diagonal and screen format

So, how should you approach the purchase of such equipment? Before answering the question of which brand of TV to choose, you need to decide on the screen diagonal. For comfortable viewing of TV shows, the following rule is not enough: small for the kitchen, large for the living room. The principle of ergonomics is quite simple: the distance from the screen to the human eye should be equal to five diagonals of the TV. So, if the size of the model’s matrix is ​​42 inches, then the chair or sofa should be on average 2 m away.

When the answer to the question of how to choose the size of a TV is clear, there remains the need to visually evaluate the perception of the picture. In a store, ask a consultant to turn on several receivers with the same diagonal and move away 3-4 m, then evaluate the image quality.

Defining the format is even easier. Manufacturers in most cases produce new models of LCD and plasma panels in the proportion 16 x 9. This choice is justified by ergonomic requirements. At first, the picture seems a little unusual. The fact is that in previous generations of receivers the proportions were 4 x 3, but it is completely unsuitable for widescreen digital content and high-definition video.

Permission

Which TV should you choose if you have already purchased a Blu-Ray player or purchased a satellite dish, that is, in cases where it is possible to watch high-definition video? In this case, you need to purchase a model with a diagonal larger than 40 inches. It is these TVs that support a resolution of 1920 x 1080. Non-digital, terrestrial broadcasting transmits a picture of 720 x 576.

But, when thinking about which TV to choose, you need to remember that when purchasing a receiver with a high screen resolution and planning to watch programs, movies, videos, being at a considerable distance from the transistor, you should not overpay for such models. The fact is that the human eye has a limit to its resolution and at a certain distance does not perceive small details for which individual pixels are responsible. If the room or its design does not allow you to install the TV closer, then it is worth remembering the rule for choosing the screen size.

Full HD, HD, or How to choose a good TV?

New technologies make it possible to transmit high-definition images. Hence the prefix of the English abbreviation HD. It stands for High Definition - “high definition”. The number of pixels determines the quality of the image. Their number during on-air broadcasting, which is received by a TV through a conventional antenna, is equal to 720 x 576. HD models have a minimum resolution of 1280 x 720 pixels. The highest figure is 1920 x 1080.

When displaying images on the screen, high-definition televisions use progressive scan technology. Unlike its four-line predecessor, it does not convey visual distortions; the screens of HD models do not flicker, saving our vision. To understand that the TV receives a high-definition signal, it is enough to see the designation “720p” on the price tag. The number indicates the number of lines simultaneously displayed on the screen, the letter indicates progressive scanning. If the TV does not receive a high-definition signal, then the “Support” line will contain values ​​from 720i.

The literal translation of the prefix Full is “reached the highest degree.” It only makes sense for owners of Blu-Ray players and satellite dishes to overpay for it. TVs that have this prefix in their name must necessarily support 1080 lines simultaneously.

Connecting other devices

When thinking about how to choose the right TV, do not forget that modern models support many functions. One of them is the ability to connect other devices. So, a good TV is simply obliged to play video not only from a USB drive, but also from a camera. The ability to connect a game console will also not be superfluous. Laptop, DVD and Blu-Ray players - in order to synchronize this equipment with the TV, the latter must have certain connectors built-in. How to choose the right TV based on this parameter?

Initially, it is necessary to separate the inputs and outputs into analog and digital. The latter include HDMI and DVI connectors. It is with their help that you can connect the latest models of digital equipment to your TV. Analogue equipment (antenna, audio system, etc.) is synchronized with receivers via component, composite, SCART and SVideo connectors.

TV and the World Wide Web

Not the last parameter when answering the question of how to choose a TV for your home is its ability to connect to the Internet. Modern TV broadcast models cope with this task without connecting them to a personal computer. Anyone who has purchased such a receiver can freely communicate with friends and relatives via Skype and have access to a library of video and television content from both international and Russian channels. In this case, the user can freely create a TV program according to his taste and preferences.

Owners of TVs that meet the requirements of the DLNA standard can set up a local network. Some models are equipped with Wi-Fi adapters. With such an adapter, there is simply no need for some connectors. Without wires, the user will be able to display photos on the TV screen, listen to music or watch their favorite movies from the computer’s hard drive.

LCD or plasma

It is sometimes difficult for consumers to understand the differences between these two technologies. How to choose an LCD TV? Or give preference to a plasma panel? One thing can be said: if the area of ​​the room in which the new TV will be placed is very large, then it is better to choose the last option. To understand why, it is worth considering its advantages and disadvantages.

Plasma panels differ from their counterparts filled with liquid crystals by their high image contrast. The gas filler reacts much faster to an electrical discharge, hence the better pixel response time. This parameter is important when playing dynamic scenes. The lower the response time, the lower the likelihood of image trailing. The wide viewing angle of the plasma panel is due to the fact that each screen cell containing gas is itself a light source. Therefore, a high level of contrast remains even if you watch the video at an angle of 170 degrees. Where the plasma panel loses is in the level of energy consumption. It is almost twice as high as LCD transistors. There is one more disadvantage: plasma manufacturers promise that the panel will operate for up to 30,000 hours, while the LCD screen will serve its owner for almost 100,000 hours.

If the listed advantages are unconvincing, then let’s move on to the question of how to choose an LCD TV. The optimal solution would be to purchase a latest generation transistor. All the imperfections of LCD screens: lower contrast compared to plasma panels, the remaining problem of the cable, limitation of the maximum diagonal size, small viewing angle. Each new model from all well-known manufacturers enters the market with improved technical performance. Of course, LCD transistors also have their advantages:

1. The screen of this TV does not fade.
2. This receiver has low power consumption.
3. At the end of its service life, it is enough to install a new lamp (in plasma, the entire panel must be replaced).

Listen and enjoy

Videos and films of high quality, naturally, cannot be perceived as such if they are not sounded at the same level. But can every TV convey the entire intended gamut? Digital transistors are, in principle, free from problems such as wheezing or other extraneous sound in the speakers, but is the sound quality? Is it possible to enjoy the so-called “presence effect”? The consumer will be disappointed with the performance of this parameter. In order to watch movies in Full HD format and hear the rustling of leaves, rumbles of thunder, and the cracking of branches in stereo sound, in most cases you will have to additionally purchase an audio system. Only some models of modern digital TVs can create an immersive effect. And there must be a note about this in the technical passport - Surround Dolby. Accordingly, such transistors are much more expensive.

If you don’t want to overpay, then which TV should you choose? What do manufacturers offer? As a rule, consultants in stores, when presenting a particular model, recommend paying attention to the power of the speakers. But is it really that important? To assess sound quality, you need to pay attention to a completely different indicator. Its name is intensity. In the technical passport it is designated by the English letter I. The intensity is measured in decibels. The more there are, the better the quality. 4 speakers of a two-way audio system are a sufficient condition for fairly tolerable sound. But their size must be at least 6 centimeters, otherwise there will be problems with reproducing high frequencies.

Contrast and Brightness

The levels of these parameters in digital TVs are not satisfactory. But when buying such an expensive toy, you need to check everything. So, brightness. Its indicator must be at least 450 candelas per square meter. The higher the number, the more comfortable it will be to watch TV programs in daylight. Otherwise, the room should simply be darkened.

Contrast is the ratio of the darkest colors to the lightest. The brighter the screen displays whites, the deeper the blacks will be. With high contrast, the screen transmits a larger range of shades and forms a clearer picture. Until recently, LCD digital TVs were significantly inferior to their plasma rivals in this technical characteristic. But the idea of ​​using LED backlighting significantly increased the contrast of LCD screens.

Design

Is the appearance of the receiver important? Gone are the days when the side panels of TVs were wide, and manufacturers produced them in the form of wooden and later plastic boxes. The frames of modern models are so narrow that it would seem difficult to come up with anything interesting. But even here, manufacturer designers were not left without work. Some models have transparent frames. And since televisions in homes often begin to take up space on the wall, in addition to them you can purchase a so-called baguette. The screen framed by it looks more like an elegant painting with a changing image. Thanks to the invention of the baguette, the question of how to choose a TV for a home made in a certain design disappears.

Decoration is an expensive idea. But it’s not just the side design that gives elegance to TV models. You can avoid disturbing the interior ensemble by choosing a receiver on a curved, cross-shaped or classic stand. And especially for lovers of deep retro, LG released a model in the style of the 60s. Monochrome screen, plastic body, chrome legs, but at the same time there is a digital tuner, the ability to connect a game console and switch channels remotely.

Nice and convenient additions

Should you choose an LG, Samsung or Philips TV? Everyone gives preference to the manufacturer whose equipment has gained trust. This is what they strive to conquer by increasing the functionality of a particular model. Each consumer can choose a TV with convenient additional features.

• The on timer is a function already familiar to everyone. The transistor turns on at a strictly specified time. For example, the TV in the kitchen will start working at 7 am, informing its owner that it is time to get ready for work.
• 24p True Cinema. All films are shot at 24 frames per second. But the DVD plays at 25 fps. This increases image speed. Some models are equipped with a function that restores the frame rate. However, it should be noted that this becomes possible only if the DVD player also supports this playback mode.
• The program guide is a convenient additional feature that rids your home of excess garbage. However, it is worth remembering that you can only ask on what channel and at what time your favorite movie will be shown if you have cable or digital television.
• Automatically adjustable volume - equalizes sound from different sources. Freeze frame will allow you not to miss a single minute of your favorite program. Child protection helps set up the TV so that the younger generation will not only not be able to turn on the transistor at inopportune times, but also some channels will simply be unavailable for viewing.

This is not a complete list of additional features that digital TVs have. How to choose one of them so that it fully meets your needs? Rely on the basic technical specifications listed above. Choose the highest indicators of a particular parameter.

Thanks to the development of modern technologies, liquid crystal or lcd televisions have gained great popularity among users. The undeniable advantages of this technology include modern design, low power consumption, small size, and ideal high-resolution image geometry. However, the task is complex: the range of products is growing, there is a lot of information on this issue. Our review will allow you to navigate the main technical characteristics of LCD devices, and useful recommendations on how to choose a TV with an LCD display will save time and money from a thoughtless purchase.

The abbreviation LCD (full name liquid crystal display) indicates a liquid crystal display in technology. From him, televisions received their modern name with the prefix “LCD”. The monitor manufacturing technology consists of using liquid crystal molecules that react to electrode discharges. As a result of these discharges, they change their brightness and color, lining up in the direction of the electric field.

The image on the monitor is made up of combined combinations in a certain mosaic order RGB triad subpixels(green, blue and red colors). Hundreds of thousands of dots make up the visual video image on the display, which we perceive as a colorful “picture” on the monitor. You can learn more about the operating principle and features of such TVs from them or.

From theory, let's move on to practical advice that will help you choose an LCD TV based on the main parameters.

What technical characteristics should you pay attention to?

Before going to buy a TV, the buyer must decide on a number of factors:

• monitor diagonal and proportions;
• matrix type and class;
• display resolution;
• brightness and contrast of the video image;
• viewing angle;
• acoustics;
• response time;
• number and availability of connectors for connecting digital devices.

Each parameter is an important aspect in technology. Therefore, it is better to choose consciously and after studying each characteristic in detail.

Features and different screen size formats

LCD TVs have different diagonals, which are measured in inches. When choosing this option, you need to take into account the minimum.

1. If the viewing area is planned at a distance of 1.5-2 meters, then a 20-26″ monitor is recommended.
2. For two to three meters – a display of 32-42″.
3. For 44-56-inch monitors, the distance for the viewing position should be at least 2.5-4 meters.

In addition to the display diagonal, all modern TVs, including LCD ones, have screen aspect ratio: width to height value. Manufacturers adhere to two proportions: 16:9 and 4:3. The second meaning occurs on TVs designed to display analogue television, the first indicates that the display is widescreen. The 16:9 aspect ratio is required for digital TV broadcasts.

Advice! To avoid mismatch between the display and image proportions, choose a widescreen screen.

Distinctive features of the matrix class

Televisions use several types of matrices, differing in their production technology. Let's look at the most standard varieties.

Technologies do not stand still, and based on the last two types of matrices, manufacturers have created improved versions that improve image quality and other parameters.

Display resolution

This criterion determines the smoothness of the transition of the color spectrum and degree of detail video images. Resolution is measured in the number of pixels horizontally and vertically. The manufacturer indicates a smaller parameter in the passport. The larger the monitor, the higher the number of pixels. associated with the capabilities of the broadcast signal.

When choosing equipment for analog TV, 720p is enough, for satellite or terrestrial – 1080p in Full HD quality. For streaming DVD movies, a resolution of at least 1366×768 is recommended.

Video contrast and brightness

Device contrast is a parameter that indicates a rich palette of different colors. The higher this criterion, the better the color rendition of the resulting video image. LCD TVs are produced with a statistical contrast ratio of 800 to 1. This proportion means that the darkest areas of the picture differ from the lighter areas by 800 times.

The next important characteristic of a TV with an LCD screen is the brightness of the image. In order not to strain your eyesight, a value of at least 450 cd/sq.m is recommended. Some models are equipped built-in sensor which determines the level of illumination in the room where the equipment is located. When you change its value up or down, the brightness automatically changes to a more optimal one for viewing.

Viewing angle

Image viewing angles can be horizontal or vertical. Their meanings must also be taken into account. This is due to the fact that when broadcasting TV shows and videos at a certain angle, the contrast is reduced and colors are distorted. The minimum values ​​of viewing angles in different planes are 160 degrees. They indicate that when broadcasting TV programs at an angle of 80 0, the contrast of the image will decrease by 10 percent, as opposed to if you look at it from the center.

Acoustics

The LCD stereo system is equipped with digital amplifier for optimal sound clarity. The latest model equipment must be equipped with at least a 2-way acoustic system consisting of tweeters and four speakers. To comfortably perceive sound, the size of the speakers is no less than 6 cm.

Monitor response time

In order for a broadcast image to appear on the monitor display, liquid crystals move from their original position to a given one, spending time. Image quality and optimal viewing comfort depend on it. This parameter is measured in milliseconds. If the response time is higher, then the picture may overlap and a loop may appear. This parameter is very important for gamers when .

Connectors and main ports for connecting devices

To turn your LCD TV into an advanced media center, it must have a standard set of built-in inputs and outputs.

1. S-Video, component inputs and composite ports. They are necessary for transmission analog signals.
2. RGB connector – with the help of it the image from the PC is transferred to the monitor display.
3. SCART – multi-channel 21-pin transmission interface bidirectional analog signal.
4. Digital DVI connector. When transmitted through this port, the signal is not converted. Using it reduces the likelihood of interference.
5. HDMI. It can transmit a high-definition HDTV signal with simultaneous audio transmission. This interface helps quickly connect the PC to the TV.
6. FireWire connector – consists of a digital system for other digital recording devices.
7. USB for media player and other devices.

Popular LCD TV models

If you have any doubts about which LCD TV is best to buy for your home, we recommend that you familiarize yourself with the best models.

Modern TV is more than just a source of news and TV series. Today, TV is a complex device that allows you to connect to the Internet, communicate via Skype, enjoy 3D reality, etc. Modern models have a lot of functions, and it’s quite easy to “get lost” among them. How to choose a suitable TV?

How to choose the right modern TV based on functionality

The capabilities that manufacturers pack into TVs turn these devices into full-fledged multimedia centers. When making a purchase, it is important not to fall for the bait of marketers and pay only for those functions that are really needed.

The most useful features of modern TVs include:

1. 3D format support. The function allows you to watch movies in the appropriate mode. One of two technologies can be implemented:
   • active – characterized by high image quality. Requires the use of special glasses with LCD curtains, which are powered by built-in batteries. The cost of such accessories is about $100 and you will have to buy them yourself, since the TV is rarely equipped with such glasses;
   • passive - provides a relatively low image resolution, although this is not so noticeable to the average user. The technology works with inexpensive polarized glasses that usually come with your TV.
2. Smart TV. “Smart” functions imply the availability of a direct connection to the Network and work on it: for example, you can watch videos directly on YouTube or read news on your favorite portal. The possibility of online communication via social networks or Skype is well implemented. In the latter case, you need to make sure that the TV is equipped with a video camera. It is also important to check how the connection to the Network is supposed to be used: a LAN port is present in all models, but a Wi-Fi module may not be present.
3. Media player. This program allows you to play photos and music, as well as the most common video formats (their list must be specified when purchasing). You can open files from a flash drive, external HDD, or receive them via the DLNA network protocol.
4. Video recorder. Designed for the TV to record the desired films or programs to an external memory source. The time shift function is also available: by pressing the button, the user can pause broadcasting.
5. PIP (picture in picture). This mode displays images on the TV screen simultaneously from several sources - TV tuner, PC, DVD player. You can switch between pictures (for example, when an advertisement ends/starts or a chat message is received). If you need to monitor two sources at once, you will need to choose a powerful TV with a pair of tuners.
6. 100 Hz, 200 Hz, etc. Such modes are designed to improve image quality by increasing its smoothness.

The more functions a TV has, the higher its cost. Everyone decides for himself what he needs. For example, if there is a slow Internet connection to the house, then the capabilities of Smart TV will not be fully used.

Which modern TV to choose: LCD, plasma or OLED?

Based on the way the picture is formed, all modern TVs are divided into several main groups. What's better?

You need to choose a TV based on your capabilities. For example, the minimum plasma diagonal is 32″, so the TV requires placement in a really spacious room.

Most users can only dream about OLED for now. But if finances allow you not only to purchase, but also, if necessary, to pay for expensive repairs, then you can give preference to this model.

Modern TV: how to choose based on screen characteristics

The display is the most important part of a TV. The user needs to decide on the following screen parameters:

1. Diagonal. The overall size of the TV and its cost depend on it. Models up to 26″ are placed in the kitchen or bathroom, up to 32″ in a living room or medium-sized bedroom, up to 42″ in very spacious rooms. A 46″ or larger TV requires that the distance between the walls of the room be at least 4 m.
2. Sweep frequency. Describes how many frames will be reflected in a second. The maximum required value is 120 Hz (this is exactly what is needed for HDTV and 3D), while the majority of TVs offer a number several times higher.
3. Permission. It plays a role only for digital television; the analog signal does not depend on this parameter in any way. Today's standards: HD Ready (1024x768 for plasma, 1366x768 for LCD) and Full HD (1920x1080).

Separate mention should be made of the so-called Ultra HD 4K TVs. Their feature is high resolution, 3840x2160, which leaves all popular formats behind. Representatives of this group are LG 65UF850V (RUB 150,000) and Samsung UE48JU6790U (RUB 72,000). It is argued on all sides that such models are the future, but is it worth buying them today?

The benefits of 4K TVs can only be appreciated with a diagonal of about 80″. Moreover, it is assumed that the viewer will be at a distance of at least 2.5 m from the screen. Not everyone has the opportunity or need to build such a “telecenter.” In addition, modern technologies have not yet reached such a high resolution:

• almost all TV channels provide a 720p picture, so the potential of 4K models will remain untapped when watching terrestrial TV;
• Internet content designed for Ultra HD is minimal. The problem is the same as above;
• Streaming games where you can enjoy 4K are also not very widely represented. Neither PS4 nor Xbox One support 3840x2160 resolution.

In general, buying a 4K model for a specific period of time seems unjustified. But it's up to the user to decide.

A modern TV is a powerful platform that combines the capabilities of a multimedia player, an Internet center and a cinema. The combination is impressive, but it will only work if the TV is chosen correctly.

Modern televisions have long broken out of the narrow concepts of devices designed only to demonstrate acceptable video and sound quality. Nowadays we are talking about high-tech devices that combine the functions of a TV tuner, computer and multimedia center. In this article, we invite you to consider together the most current characteristics and capabilities of televisions, which may be useful in choosing the model that is right for you.

Picture and sound quality

Screen resolution . This parameter is really important, since the clarity of the image on the screen largely depends on it. Resolution is especially important for large-diagonal TVs. Today, the most common TVs with resolution formats are HD ready (1280x720 pix), Full HD (1920x1080 pix) and Ultra HD (3840x2160 pix).

Ideal image quality is achieved only when the resolution of the video signal completely matches the resolution of the TV screen. In any other option, it will be necessary to use signal interpolation using software methods, adjusting it to the physical resolution of the screen matrix. Therefore, when choosing a TV resolution, you should take into account the type of signal that will be supplied to its input: terrestrial or cable television, DVD or Blu-Ray format, etc.

Motion Enhancement Technology . Modern manufacturers prefer not to indicate the actual frame rate, which mainly affects the quality of motion transmission on the screen. Most often, the specifications describing the main characteristics of televisions indicate only virtual complex values, which sometimes reach fantastic values ​​of 600, 800 and even 1200 Hertz.

On Samsung TVs this is Clear Motion Rate ( CMR), LG has Motion Clarity Index ( MCI), and Philips prefers to evaluate the quality of dynamics in the Perfect Motion Rate ( PMR). These values ​​are practically incomparable between different brands, but in the model range of one manufacturer you should choose a TV with a higher index.

Acoustic format . The built-in acoustics format used by most budget TV models is 2.0. (two wideband stereo speakers without a subwoofer) practically does not transmit the low-frequency component of the sound. Therefore, developers are forced to use various software methods to improve acoustic characteristics.

For better sound quality, it is preferable to choose models that use the 2.1 format (with a subwoofer), which provides acceptable bass sound, or use external speaker systems in 4.1 or 5.1 format.

Additional features and functionality

Smart TV

A high-quality TV with Smart TV function should have the following properties and components:

• High qualityweb browser;
• Intuitive interface;
• Be integrated into social networks;
• Built-in media player that allows you to play files from externalUSB devices and memory cards;
• On-board webcam or the optional ability to connect it to use the serviceSkype;
• Access to the company's application store;
• Be equipped with alternative control and access methods (voice, gestures, visual user identification);
• Have a sufficient set of pre-installed widgets.

Some manufacturers have taken care in advance about the possibility of upgrading their Smart TVs. For example, the South Korean company Samsung has launched the production of external replaceable modules Smart Evolution, allowing you to update the software of last year's models, providing them with new functions and capabilities.

Support 3 D

Today, active and passive technologies are used to create three-dimensional images on TVs. The advantages of active 3D include high picture quality, which does not require additional software processing, while passive 3D impresses with its simplicity and convenience. In addition, passive systems are easier to manufacture, which has a beneficial effect on the cost of the TV.

When choosing a high-quality, top-level device, you should remember that main characteristics of TVs The following 3D features must be enabled:

• Adjusting the depth of the volumetric image;
• Converting a flat image to 3D;
• Supports simultaneous use of the screen by several users (playing together, watching different TV programs).

Data exchange

As the fleet of household multimedia devices grows, the role of technologies that facilitate the exchange of streaming content and media files between them is increasing. Among the features that should be present in premium models are support for the following technologies:

• DLNA , allowing you to combine all homeHi-Tech devices into a single local network (LAN);
• MHL , providing a wired HDMI connection between TVs and mobile devices for display on the big screenFullHD content;
• Miracast (Wi-Fi Direct) , providing the transfer of multimedia information from one device to another via a channelWi-Fi directly, without combining them into a LAN network;
• WiDi , which allows you to mirror the image shown on the display of a mobile device paired with it onto a large TV screen via a channelWi-Fi without using a router;
• NFC, which makes pairing other devices with the TV as convenient and fast as possible.

All methods of information exchange used by various manufacturers of TV receivers are based on these technologies; it’s just that developers prefer to call these TV capabilities differently, adding sonority and attractiveness to them.

Communication capabilities

Today, almost all lines of TVs are equipped with a comprehensive set of connectors necessary for full operation and switching. Typically, the difference between models of different classes lies only in the number and versions of installedHDMI- And USB- connectors providing high speed broadband signal transmission.

The USB interface is the most common and convenient. Many premium TV models are already equipped with the most advanced type of USB version 3.0. As for HDMI ports, today some Hi-End TVs support version 2.0. of this interface, which allows transmitting ultra-high definition UHD video signals.

In addition, the HDMI interface can be used to connect all home devices into a single multimedia network, each of which can be controlled from a single television remote control. Almost all manufacturers use this function. LG calls itSimpleLink, Samsung - Anynet+, and Philips - EasyLink.

Premium TVs require additional slots for connecting external memory cards of various standards (Compact Flash, Memory Stick or MMC), which can be used in parallel in portable cameras and mobile devices.
