How to choose a TV: orientation on the size and scope

TV has long ceased to be a luxury or some inaccessible object. Huge home theaters, not everyone can afford, but the installation of the usual small electrical appliance is now available to everyone. Before you select TV, you want to see that offer shopping centers, and clearly understand the purpose for which the device is purchased. That is why, how and where will be operated device that determines the set of functions that affect the price.

How to choose a TV for the home: what to look out for

More competition between producers leads to the fact that almost every month goes on sale televisions with new features and functions. Firms are now trying to not only make the screen bigger, but also improve the quality of the transmitted image, sound and other technical characteristics. Therefore, before you choose a good TV in the first place, experts recommend to decide for what purpose it will be used.

If the equipment is purchased solely for watching movies, you can safely give up many functions. When the device is used mostly for games, there is better not to save and buy a device with a maximum resolution and the ability to connect to the Internet.

For many buyers, the determining factor is the price of LCD TVs, because you can buy as a small model with a standard set of functions for 10 thousand. rub., and give everything to the full with the purchase of a large widescreen display with maximum possibilities.

Rely solely on price is not considered correct. So before you buy you need to determine the financial limits and to explore all the television sets that are in acceptable price range, and their functions. It is important to understand that the device is not available for one year, so the choice should be done after careful consideration and, in addition to price, should pay attention to such important parameters:

• screen type and the backlight;
• and the diagonal size;
• resolution;
• the refresh rate of the image;
• audio transmission quality;
• convenience of the interface;
• additional options;
• operating system.

The main types of screens: LCD, plasma and LED. What is it

The first thing you should look for when buying a TV - type screen, where the market is represented by a large number. The most old-fashioned option is considered to CRT TVs, which not only has long lost its relevance, but is outdated by several decades. However, despite this, even now in stores you can find these options, because they are low cost, easy repair and a long service life. By the significant disadvantages include:

• impressive dimensions of devices;
• minimum number of functions;
• negative impact on vision.

LCD screens - models, which are peculiar to the low cost, good quality of the transmitted image, small size, and high color rendering. A key disadvantage of this option is considered to be a TV high propensity to burn under direct sunlight. If you install the TV near the window overlooking the brightly lit south side, after a while spots may appear on the screen.

TVs with LED-screens are among the most advanced, because these ICE TVs, unlike LCD screens using LED matrix illumination. This feature affects the size of the equipment and allows you to make television even more thin and light. The image is of good quality, but the device consumes more power.

In the plasma display panel does not consist of crystals in the LCD, and of cells filled with a gas, for this reason, these TVs also called gazoyacheistymi. Design features provide a good quality image is displayed, and the screen is resistant to fading. Use negative aspects are considered high energy consumption and frequent overheating of the device. And no plasma TVs with a slight diagonal, the minimum dimension of the plasma - 32 ". Most budget price of a plasma TV with a diagonal of 40 "is 50 thousand. rub.

Projection and laser options: important parameters screens

About 10 years ago we entered the market so-called laser screens, which provide long service life and improved image quality. Thanks to modern energy-saving technologies the device does not consume a lot of electricity, and makes it possible to watch high-quality picture. The main drawback - high cost of equipment.

Projection TV models are characterized by an optimal price / performance ratio. However, these devices are susceptible to the appearance of the dummy pixels that spoil the image quality. Over time, some of the screen can burn, which adversely affects the color reproduction. Another negative aspect of the use of a projection screen is considered to be a limited viewing angle, which also does not add to the popularity of TV sets.

Regardless of the type of device, the screen may have two variants of the coating:

1. Glossy. When light enters the screen glare and image distortion. The picture itself is bright and saturated. Some models are further equipped with anti-reflection coating.
2. Matt. Covering not scary exposure to direct sunlight, because it does not appear glare, but colors are not as rich as in the glossy version.

Recently, in shopping malls, you can see the curved screen, which until recently was attended only by an expensive premium segment, and is now available in low-end models. Bent form screen provides a proximity edges matrix relative to each other, which allows to narrow the field of view. This feature makes it possible to relieve the load on the eye, because the view is focused on a smaller angle. However, this effect can be achieved only zooming the screen at maximum distance, or by setting the TV with a big diagonal.

How to choose a TV with optimal size: the size, depending on the area of ​​the room

The size of the diagonal depends from what distance to watch TV, not to unnecessarily strain the eyes. Very often the customer when choosing the art chasing large screen size, while forgetting to correlate it with the parameters of the area and room where the appliance is installed. Surprise guests a large screen in a small room, of course, turn out, but to enjoy the long view will not work, because the eyes get tired quickly.

Helpful information!When translating inches to centimeters, note that 1 inch equals 2.54 cm. Therefore, if you want to know what screen size of 32 ", this figure should be multiplied by 2.54 - 81.3 will see as a result.

Looking through the characteristics of TVs, you must know that the first two digits represent the labeling namely diagonal size, that is, meaning the distance between two opposite corners monitor. Measured rate in inches. It should also be borne in mind that the size of the screen does not always coincide with the TV size, which is usually a bit more due to the extra frame. It should be noted that the current model of "Samsung" TVs are so thin frame that the device size is almost the same as the screen parameters.

In the selection of televisions on the parameters you can give preference to the expensive model having diagonal of 55 ", but if you put a screen in a small bedroom, then the desired effect will not work achieved. This is due to the fact that the eyes will quickly get tired, which may even lead to constant headaches.

Experts recommend that when choosing equipment for the home use of a simple formula that allows you to select the optimal size of the diagonal. To do this, the screen size in inches multiplied by 3 and divide by 100. Thus, to the TV 40 ", which means 101.6 centimeters, calculate the optimal distance in meters is as follows: 101.6 x 3/100 = 3.048 m.

From this it follows that the most suitable distance to the TV from the eye level should not be less than three meters. The best size of the diagonal for the kitchen TV considered parameters from 19 to 24 inches. There is no sense to put a big screen for the reason that in this room the TV more often listen than watch. Therefore it is better to pay attention to the audio settings.

For a small bedroom area of ​​15-18 m² The optimum size of TVs of 28-32 inches, which is best viewed from a distance of 2-2.5 m. can be purchased in a spacious room and large widescreen display with a diagonal of 40 to 55 inches, but it is important to know how far better to watch TV, to enjoy the view:

• 32 '- 1.2-2 m;
• 40 "- 1.5-2.5 m;
• 46 "-1,8-3 m;
• 55 "- 3-3.4 m;
• 65 "- 3-4 m;
• 80 "- 3,7-5 m.

Interesting information!The largest TV promoted by C Seed. The device differs 4K resolution system and has a diagonal of 262 inches, which is 6.65 m Price model -. 540 thousand. dollars, and weight - about 800 kg. For the first time the TV went on sale in the summer of 2017.

Resolution, frequency and format of your TV: prices of electrical appliances

Technical characteristics of flat-panel TVs need to be taken into account always, because they also affect the image quality. Among the key parameters should be allocated resolution TVs. This characteristic is an index that specifies the number of functional points per unit screen area.

In other words, the image size in pixels, from which depends the sharpness of transmitted image at the screen. It is important to consider the number of pixels in the horizontal and in the vertical plane.

The main varieties of expansion and key features are presented in the table below:

Format	The number of pixels	Description
HD	1280x720 1366x768	The main type of resolution, presented in most LG and Samsung TVs. This is sufficient for small kitchen appliance or TV for the bedroom. Prices start at 5-6 thousand. rub.
Full HD	1920x1080	The most common variant in TV medium-sized - up to 32 ". The main advantages of TVs Full HD- reasonable price, good quality pictures. Prices - from 5 to 30 thousand. rub.
Ultra HD or 4K	4096h2160 3840h2160	This extension is available mainly in TVs larger than 32 ". Characterized by excellent image quality, but the high price of the TV - from 50 thousand. rub.
Ultra HD or 8K	7680h4320	The ultra-modern screens, to acquire that so far in our country does not make sense, because there is no programs or channels that transmit the image in this expansion. Characterized by a small selection of options, high price - from 250 thousand. up to 1 million rubles. and more

Choosing a TV with a specific resolution, we must focus not only on price but also on the purpose for which the equipment is purchased. If your TV is only for watching analog broadcasting or cable, buy expensive TV with a maximum resolution makes no sense. High resolution Ultra HD (4K and 8K) are only necessary if you plan to watch movies with high quality images or to connect to technology game console.

TV format draws directly on the resolution, but in most cases the instrument is present widescreen display with parameters of 16: 9. This figure is considered to be the most popular, because it is supported by most of the channels, downloaded films and programs.

Based on studies conducted by scientists, that figure of 16: 9 is the best for human perception. If you familiarize yourself with the reviews of TVs, it becomes clear that a fairly popular are other formats, such as 21: 9 and 16:10, but it should be noted that these characteristics are unique to Screens more than 55 ".

Frequency brightness, contrast ratio of the TV: What is better to choose specifications

The refresh rate indicates how many frames per second can appear on the screen. Index Measured in Hertz (Hz). It is considered the most common refresh rate of 60 Hz, which is enough for comfortable viewing of most films. If we ask what is different from the TV screen, you can see that it will be just about this one, because for dynamic modern games 60 Hz is no longer enough, and this figure rises to 144 or even 240 Hz, which allows you to immerse themselves in the virtual world.

Sometimes refresh rate confused with a frequency response which is measured in milliseconds and mean velocity of the liquid crystals from a horizontal to a vertical position. According to reviews, the TV with a response time of more than 8 milliseconds in the case of viewing the scene with fast-moving subjects freezes, and the edges of the image are blurred.

It is interesting!The faster screen response to the change, the better the image quality when viewing dynamic scenes. However, not everyone will be able to capture these changes on the screen.

When you buy should pay attention to such a nuance, as the contrast, as in the description of the goods are such abbreviations:

1. HDR. Means a high level of contrast between light and dark shades, as well as between the more vibrant colors on the screen: red, blue, green. This figure provides the image maximum realism.
2. HDR10. Supports 10-bit deep shades, making the picture more vivid and bright. This characteristic is inherent in devices with longer extension 4K.

In a separate group can be identified TVs capable of transmitting three-dimensional 3D-image. We should not forget that in this case, as when watching movies in the cinema, it is necessary to use special glasses. If you read the reviews of the TVs, we can note that this function is not gained wide popularity and gradually receded into the background, not only because of insufficient image quality, but also because of the lack of a large selection 3D content.

If you want to buy a large TV, you need to pay attention to the sound quality. In the case of a small TV is not enough space to build a good speaker system, which is not the large-format screens. When the sound is a defining characteristic, it is necessary to pay attention to the presence of options such as:

• integrated subwoofer;
• stereo capacity of at least 20 watts;
• Dolby Digital sound system.

Types of templates for TV: the main advantages and disadvantages

The matrix is ​​considered a basic element of the media device, which directly affect the quality of the transmitted image. Depending on the TV matrix type image on the screen has some peculiarities. You can not always see the difference with the naked eye, sometimes it takes a look at the display under different lighting and from various angles.

Features of arrangement of liquid crystals, their combination and a method of motion detect the presence of anti-reflective coating and the ability to view television without distortion regardless of the viewing angle. The quality of the matrix and the life of the product depends. Allocate such basic types of matrices:

1. LCD, the so-called Liquid Crystal Display, they are also LCD monitors, which due to the low price and economical energy almost completely replaced the plasma screens.
2. LED, or Light Emitting Diode. Led-TV - which means that the device uses a certain type of backlight.
3. Plasma. It differs fundamentally different technology, when used in the screen manufacturing gas which refracts and emits light when current flows.

The main element of Liquid Crystal Display matrix is ​​liquid crystal that an electric current is able to change the position of the molecules in the space of the screen. The liquid crystal matrix in TV consists of the following components:

• a liquid crystal layer;
• a layer of transparent electrodes disposed on the sides of crystals. With this control layer occurs crystals transmit light;
• color filter responsible for the color dots or pixels;
• the backlight located on the rear of TVs matrix;
• external glass or a special film that serve to close the front of the screen.

The operating principle of an LCD TV is in action crystals from the electrodes through which current flows, resulting in a change in the molecular structure of the crystalline substance. As a result, light passing through this layer, is refracted and is incident on the filter, whereby the point on the screen is the desired hue.

TN matrix was first used it in an LCD TV. Because of the simplicity of the work price of plasma TV with a matrix is ​​the most accessible, even if we are talking about an instrument with a large diagonal. For this reason, the device is very popular among buyers. This type of matrix is ​​composed of liquid crystal arranged perpendicular to each other in a spiral. Irregular rotation of the particles leads to the fact that when viewing an image at different angles is its distortion. This moment is considered to be the biggest drawback.

It is interesting!TVs with TN matrix is ​​not necessarily true color reproduction, and sometimes appear on the screen dead pixels, unable to provide a high-quality image. many firms add Film coating for improving the viewing angle.

Other types of matrices used in modern televisions

IPS technology is considered to be the elder brother of the matrix TN, which were corrected its main shortcomings, which resulted in the emergence of more high-quality equipment. In this matrix-type liquid crystals are all located in one plane parallel to the screen, which allows the elements to rotate simultaneously. The main advantages of using IPS technology include:

• enlarged viewing angle;
• obtain a clearer picture and a high level of contrast;
• deep and correct colors;
• extended service life;
• reduction of harmful effects on the organs of vision.

Among the shortcomings can be identified high price for TVs, as well as a low response speed, which can be observed in some models. Part of the user notes and the lack of transmission in black. Similarly, the principle of operation and the matrix differs PLS, which has a high throughput of light and more energy efficient, but such televisions have a low brightness level. Considered the most expensive TVs with AH-IPS and P-IPS systems, because they are distinguished by a higher quality of the transmitted images. The most cheap matrices include E-IPS.

Averaged option TN and IPS considered VA system that is used in most modern TV models. In this case, the liquid crystals are in a perpendicular position relative to the plane of the screen that provides a more saturated black tone which can not be obtained in other matrices. The crystals in the system VA move freely and provide a high-quality image by changing the viewing angle without distortion at the same shades. This type of matrix is ​​constantly being improved and updated to include the latest developments MVA and PVA.

What is an LED-TVs, other types of backlights

On the final cost of the TV and on the quality of the resulting image also affects the type of illumination. The following will be considered, which means LED-TVs, as well as their basic versions.

Modern technology, which provides a good viewing angle, equipped with Edge LED system, where LEDs are located on the contour and create the effect of a luminous frame. The technology enables thin, light and cost-effective devices.

Improved technology is considered Direct LED, when diodes are already distributed on the entire screen surface. Thanks to the autonomous operation of each diode is regulated by local dimming that allows you to get quite bright and high-contrast picture. TVs equipped with such a system, give the opportunity to enjoy a more colorful image.

No backlight unit is observed in televisions with QLED system. In this case, quantum dots are used, playing the role of the backlight. Such TVs most correct color reproduction as well as very easily perceived by the human eye. Price ICE TVs slightly higher cost of the other models, but it does not affect their popularity.

The latest development is considered to OLED technology, where diodes are used instead of the illumination unit, coated with a substance - a phosphor that glows when passing therethrough electric impulse. TVs have the largest viewing angle, and when viewing programs on such eyes will not tire quickly screen. The downside of technology is considered to be a high price.

LG or Samsung: Which TV is best, depending on the type of illumination

QLED system first used it in an ice-TVs "Samsung", so the matrix of this type are found only in the South Korean manufacturer. Despite the fact that OLED technology has been developed by engineers the LG, it can also be found at other manufacturers.

In 2018 on sale left the flagship "Samsung" - white TV QLED Q9FN, which once was a competition device LG OLED65E8, released in the same year. The main difference between LG Samsung's model is considered not as clear, colors black spectrum. However, when displaying a mixed picture with black and bright colors in the TV "Samsung" dark areas dominated by obscure and little bright colors, which is not the appliance LG. Unlike OLED-TV QLED, due to the presence of anti-reflective coatings, better preserves contrast in bright light.

Advantage TV LG considered high contrast for dark scenes, because elementary pixels of dark tones can be disabled, and thus not violate the brightness of adjacent pixels.

Interesting information!When buying a company TV LG and Samsung will need to choose between a more active medium brightness LG and Samsung high dynamic range.

With regard to the definition of the image, it can be argued that QLED Q9FN little left in the gap due to the granular permissions 4K. Although LG OLED display gives a more detailed close-ups, in the case of large-scale image of the scene is much inferior competitor. Another advantage, which is different white TV "Samsung", is considered to be the best color rendition.

Many users have reported that the bright image of the TV screen LG may distort the color and, for example, instead of showing an intense blue blue tone. In general, both models have both advantages and disadvantages, so when you select should be guided by personal preference and trust in a particular brand.

Benefits of Smart-TVs to the Internet

When buying a TV with Internet access, you can get rid of the need to wait for your favorite transmission, broadcast football, because in the network there are always resources for watching movies, clips and series. Opportunities Smart TV can surprise any user. With this TV, you can easily stop watching a movie and be distracted by other things. You can not get out of bed, go to social networks and chat with friends. The convenient location of the widgets on the screen allows you to quickly find your site and go to his view.

When choosing a very good TV with Smart-system need to be familiar not only with the interface, but also with the technical possibilities. For example, in LG TVs on the screen set television icons. Samsung puts on the screen social networks, gathered in one Social TV folder. Panasonic's catalog of SHOUTcast makes it possible to listen to your favorite radio station. Number of widgets can be increased, downloading them on official sites: some of them are paid, and some can be downloaded free of charge.

Another useful feature of Smart TV is considered SimplyShare option to link the TV to any device that supports wireless Wi-Fi network. This feature provides a fast connection to the computer or telephone, when it is possible on a large screen display the photos you want, or video.

Control function makes it possible to control your TV, not only with the remote control, but also using the smartphone, tablet, or computer. Considered useful USB-Recording option to while watching the digital channels on the air supply to the transmission of a pause and some time to watch it.

It is interesting!It can be said that Internet TV has many advantages compared with simple models.

TVs with wi-FEMA and other useful functions

Modern technology is filled with a lot of features that simplify life, not spared this statement and televisions. Today, even equipped with wi-FEMA, which allows you to surf the Internet without being distracted from the screen, it is hard to surprise. The main advantage of TV with WiFi - no need for additional cables to connect to the Internet, which are required if there is only LAN-connector. Other popular features of TVs:

1. Anti-reflection coating. It allows to obtain a normal image with intensive light. Particularly relevant function for bright rooms.
2. Picture in Picture. Option, which previously could only dream of many, makes it possible to simultaneously view multiple channels.
3. The ability to use the card. The presence of the connector allows the use of SD-card from your phone or other recording device to view photos or videos.
4. 24p True Cinema. Function allows the TV to transmit the image with the frequency with which it has been removed - 24 frames per second, allowing you to remove stress from the eyes.
5. TimeShift system. Available only in Smart TV and allows you to pause the transfer, which is broadcast live on television.
6. Control with your voice or gestures. This function eliminates the need for constant search for the remote.
7. The list of favorite programs. Add to favorites just right, you do not have to scroll through a large number of TV channels.
8. Progressive Scan. The technology allows you to add an image definition and a better quality due to consistent supply of personnel.

How to set up channels on TV that this requires

Those who buy a TV to a greater extent for streaming broadcast, should be aware of what kind of built-in tuners must be present in the art. If the current models have almost all the features you need, the budget option may be available only to one or more tuners. To perform the TV settings on certain channels, you need to know such basic types of tuners:

1. DVB-T. This embodiment relates to a terrestrial digital broadcasting standard, capable of transmitting a high quality signal, but it does not take more than 10 channels.
2. DVB-T2. An improved model, which "catches" 32 channels. Video of high quality and that the apparatus has a stable relationship with the repeater.
3. DVB-C. Standard, allowing you to view cable TV in digital format and in high quality.
4. DVB-S and DVB-S2. The newest models used to broadcast satellite channels. In contrast to all other devices make it possible to view channels in HD the best quality, which is especially important if you have installed a good TV with higher resolution.

After connecting the antenna to select all of the available channels, you should enable automatic setting or perform a manual search.

In shopping centers a large selection of various models of TVs from different manufacturers, which differ not only on price but also on functional filling. Start your choice should be to determine the optimal size of a diagonal, depending on the area of ​​the room, and then you can proceed to the consideration of other important characteristics. Before buying the chosen model, you need to pre-read the real reviews, which sometimes give more information than the sales consultants.
