TV diagonal size is always indicated in its name, for example, if we take the model of the company «Samsung» UE-65HU8700, the number 65 and will indicate the size of the screen. And other manufacturers: usually the first 2 digits of the model - this is the designation of the size of the diagonal, which is measured in inches. Sometimes an additional package is found and the size in centimeters, which is equivalent to the parameters in inches. To convert inch value to centimeters, you need to multiply that number by 2.54. For example, 19-inch TV screen size is 48.26 cm.

size of the TV is not connected with vertical or horizontal settings, because the diagonal - the distance between two opposite corners of the screen from the upper left to the lower right corner. Another important point to be taken into account - is that the overall size of the TV will always be more diagonal. This is due to the fact that this figure does not include the frame, framing the screen, which is typically a few centimeters more.

Modern flat, are so thin frame that its size does not affect the total value of the diagonal of the unit. Before the TV diagonal measure need arm centimeter or tape, to attach one edge of any corner and the upper stretch meter to the opposite bottom corner. Thus, you get to know the size of the diagonal of the TV to see. To put the figure in inches, divide the resulting number should be 2.54.

How to choose the device depending on the screen size: diagonals TV table in cm and inches

Learn the TV diagonal (as well as its width and height) can be in describing the technique on websites or in shopping malls. If the value of the diagonal is mainly used once in the model name, the information about the width and height of the screen will have to look for. These parameters are also important because the size of the transferred images on the screen depends on the aspect ratio. Initially produced TVs with a screen aspect ratio of 1: 1, which was associated with an obsolete format video footage. Then developed format 5: 4, which was closest to the latest size.

Most modern TVs 20 inches, like other models in size, the aspect ratio is 4: 3, when the screen form is close to the square. 16: 9 is more typical for large-sized TVs: 50 inches, 42, 60 or 78. In this case, the screen has a more rectangular shape.

Choosing the size of the TV, depending on the type of screen

Choosing the size of the diagonal of the TV - an extremely important task for the purchase. In addition, you must pay attention to the type of screen. Consider the most popular varieties of TVs.

LED-displays are composed of a liquid crystal matrix with integrated lighting system, comprising a small reflective diodes. Due to these characteristics TVs provide maximum color depth, as well as ensure a more realistic their transfer. It yield LED-screens has greatly expanded viewing angle unlike the CRT or PDP TV. Modern technologies have ensured that most popular models can be viewed at an angle close to the 180˚.

OLED-TVs are advanced models, the production of which crystals are not used, and image transfer is performed using only diodes. In this case, each individual pixel is illuminated independently.

Thus, OLED-TV 32 "will have a higher quality image and saturated than liquid crystal monitor with appropriate parameters. This is ensured by the fact that modern TVs Diode technology transfer sharper and colorful image. Similar characteristics differ TV "Samsung" 40 inches and the other models, especially for that QLED technology was developed.

Useful advice!High quality and sharpness of the displayed image was allowed to have a TV with OLED technology QLED and a little closer to the eyes, because they have the least harmful effect vision.

The choice of the diagonal will also affect the shape of the screen, because now, in addition to the standard flat-screen TV's popularity began to gain curved shape. It is important to know that you need to choose the size of the TV 60 inches and larger, because the small screen all the advantages of a curved array will be lost. The advantage of curved models is approaching the screen edges to each other, making it easy to focus on the image at a lower voltage organs of vision. The price of high-quality television with a curved shape will be higher than the cost of flat panel models with similar properties.

Support TV function HDR is also considered an important characteristic when choosing equipment. The introduction of this technology has improved brightness and contrast, which directly affects the quality of the picture, and, consequently, the choice of the optimal screen remoteness from eye level. These TVs allow the user to enjoy a more natural image.

How to choose the diagonal TVs, in accordance with the features of the room

special formula has been developed to make it easier to make the right choice of TV size, expertise, by means of which will determine the TV-inch (diagonal of it). Thus, if the purchase screen with good resolution Full HD, the optimal distance from the eye to which the level of 2 m, it is required that the distance (in cm) divided by the factor 1.56. The result of calculation becomes optimal screen size (in cm), most suitable for the space. To put the figure in inches, you need to divide that number by 2.54.

It is important to know that the better the quality of the screen, the closer it can be located. For example, a model with a resolution of 4K or 8K is possible without compromising the health viewed from a distance of 1.5 m. The better the image quality, the more expensive it will cost equipment.

When purchasing a TV for indoor use, many users allow a big mistake and pick up the most possible under the budget diagonal, not taking into account neither the size nor the shape of the room, without taking into account the place mounting. If the room has a small area, install a large plasma TV 50 inches, a long time do not get to look at a screen, because there are tired eyes and sick head.

Another important consideration when using a large liquid crystal screen becomes the fact that a TV-marker will be heated and to increase the room temperature.

Useful advice!Do not choose the diagonal of the TV based on the impressions received after viewing device, which is in the point of sale. At the supermarket on the stand big TV would look expensive and elegant, but in a small space of the eye it is difficult to focus on such a large image.

Before buying tips to make a small screen rendering in the room where you plan to place the device. To do this, select several preferred diagonal TVs, and then in the place of installation on the wall to hang a poster, which corresponds to the size of the screen. Then you need to sit comfortably at the planned view and try to understand whether the selected size and whether it will fit into the surrounding interior will do.

When selecting the optimal number of inches of the TV it is important to consider not only the area, but also the layout of the room, its actual use. For example, choosing kitchen TV, it will be appreciated that the screen does not interfere with the process cooking and closer to the edges of the heat sources, including fireplaces, radiators, heating surface and heaters.

In short, the ideal is considered such a diagonal size of which is 2 times less than the distance from the instrument to eye level. Another thing to consider is considered the fact that the eyes should cover the entire area of ​​the screen, as in Otherwise, not only will not be visible portion of the image, but may cause problems vision.

The ideal ratio: table diagonal TVs cm in view of an optimal distance from the eye

Many manufacturers in the production of televisions take into account features of the use of screens in different rooms. So, AVEL company released a special 22-inch TV, is designed for use in the kitchen - this is the model AVS 220K. This TV can be mounted on the wall or built into kitchen cabinets. Due to the fact that the screen is made of durable tempered glass and has a level of protection against dirt, dust and moisture, relevant European IP-65 standard, it can be used not only in the kitchen but also in a bathroom. The price of the TV - about 41 thousand. rub.

If you can not choose such an expensive model of the TV, you still need to consider when buying a screen strength and its ability to withstand the aggressive kitchen environment. The optimum size of the diagonal of kitchen appliances - and from 16 to 26 inches. It should take into account such recommendations on the choice of the device, depending on the area of ​​the room:

1. The small kitchen area 12.8 m² do not install the screen more than 19 inches - the best size is considered to be 17 ".
2. The average floor space of (12-15 m²) Make it possible to buy a TV with a diagonal of 22-26 '.
3. The large kitchen (20 m²) In the room, united with a dining room or the kitchen-studio is quite possible to hang a TV of 32 inches.

As a rule, the most big TV set in the living room, which is often used as a home theater. That's a big diagonal of the TV at the same time allows multiple people to comfortably view the screen. On this basis, allocate these recommendations:

1. To select the optimal diagonal TV with Full HD resolution calculation is as follows: the distance from the screen to view multiplied by 25 points. Therefore, if the screen is located at a distance of 2.5 m, it is considered an ideal diagonal size of about 62 inches.
2. If you purchased a more expensive model with a resolution of 4K, in this case, to calculate the optimal diagonal need to multiply the distance to the TV 39. Therefore at a distance of 1.5 m can be secured large TV of 60 ".

The bedroom TV can be seen mainly in the supine position. In this case, you can use the same calculation as in the selection screen for the living room. We should not forget about the choice of an optimal distance from the screen.

Table distances from the TV depending on the diagonal in view of the most widespread resolution HD:

Diagonal inch	Equivalent cm	The optimum distance up to the eye, m
14-17	35,5-43,2	1-1,5
22-25	56-63,5	2-2,5
26-32	66-81,3	2,5-3,5
32-42	81,3-106,7	3-4,5
42-55	106,7-140	4-5,5
60-80	152,4-203	5-7

These figures are considered approximate, because the error in the placement range from 0.3 to 0.7 m. In this also takes into account the type of installation when the screen can be built into furniture, put on a shelf or mounted directly on the wall.

What you should still pay attention to when choosing the optimal size,

To select the most appropriate diagonal must first determine the primary purpose of TV shopping. For example, if the screen is chosen exclusively for viewing content in a high quality and in 3D format, you should choose maximize the long diagonal, which allows the size of the room, and you need to take care of the corresponding set functions. In this case, the optimal size of the TV - 49 inches and larger. In addition to selecting the number of pixels, you need to pay attention to other features, such as:

• contrast;
• color;
• Update frequency;
• delay time.

If the main goal - the game, then there is a connection to the console or a computer, you can choose a small diagonal, because the screen is required to be placed on a small distance. More attention should be paid to the high frequency of updates and a good image matrix. Not bad in this case, buy a model with the function of the smart TV.
