How to find out how many inches the TV screen

3 ways to find out the diagonal size of your TV

What are the criteria for choosing a TV? Technical characteristics are very important, but first of all you need to decide on the diagonal. Few people know how to measure the diagonal of a TV. There is nothing difficult in this. Now let’s analyze this moment.

Mostly consumers, in the process of choosing the optimal TV device for themselves, take into account the size of the equipment and the characteristics of the screen. After all, the level of comfort while watching a series, TV program depends on this.

find, many, inches, screen

The calculation of the dimensions of the TV is carried out by measuring the diagonal of the screen, but few of the users know which unit of measurement is wiser to use. There is an opinion that the diagonal of a TV device in centimeters is larger. This information is not true. Now let’s analyze all the nuances regarding the rules for measuring the screen.

How to convert inches to centimeters correctly

Inch (2.54 cm) is not the most popular unit of measurement. Despite this, this unit of measurement continues to be used. This value is considered a little outdated today based on the new SI rules. over, there are plans to even withdraw inches from circulation.

At the moment, this has not yet happened, so this unit is used when indicating the size of the device, especially by TV manufacturers. Companies designate screen size this way. Despite the fact that it is easier and more familiar to calculate the screen diagonal in centimeters, calculations are still carried out in inches.

″ Is the designation of an inch used in the description, instructions, etc. It does not bother users to measure the diagonal of TV-devices not only in inches, but also in cm.

The key parameter of the TV screen is the distance, which is measured between the left and right corners of the matrix. Use special automated converters. These online services allow you to convert different units of measurement. At the same time, these programs will not answer you the question of how to determine the diagonal. But they give information about how many centimeters are in a particular value. Consider an example, a calculated screen of 40 inches is about 102 cm.

Before finally choosing the model and size of TV, it is recommended to look at the table of base values ​​and get information about how many cm in a particular screen, then make your own calculations.

In order not to waste time converting the diagonal to centimeters, use this table:

Value in dm Value in cm
22 ″ 60 cm
32 ″ 82 cm
37 ″ 94 cm
40 ″ 102 cm
42 ″ 107 cm
fifty” 127 cm
60 ″ 152 cm
70 ″ 178 cm

Diagonal measurement

How to find out the diagonal of the TV? There are several ways. Often the box of equipment is thrown away, but the instructions cannot be found, then you can choose one of the options presented:

  • Find TV model on the Internet.

How to measure the diagonal of a TV? For this process, you need to arm yourself with: a tape measure, a meter (you can use a ruler), a sheet of paper and a pen. If you are not sure of the correctness of the calculations made in your mind, it is better to take a calculator.

Consider a guide on how to manually measure the diagonal:

  • From the corners of the screen of the upper right to the lower left, we stretch a tape measure (meter). Please note that the body of the device is not taken into account. After that, we check the tightness of the tape along the entire length. If there is no tape measure, then you need to take the thread, pull it along the TV and cut or mark another corner. Then measure the length of the thread using a ruler.
  • We take a pen and paper, indicate the obtained measurements in cm.
  • We carry out simple calculations. Accordingly, you will need to convert cm to inches. The resulting measurements in cm are divided by 1 inch (2.54). If it is difficult to divide into a column, use a calculator.
  • When the meter is not enough to calculate the size of the device, you can use the second calculation option. You will need to measure the sides (width, height) separately.
  • Now you need to carry out calculations according to the Pythagorean theorem. We square the length and width, add them and extract the square root from the resulting sum. To avoid oversights, use a calculator. The result must be converted to inches (divide by 2.54).
  • Another easy way to find out the diagonal of a TV is to take a close look at the TV case. Often it is not the diagonal of the display that is indicated, but simply the distance from the top to the bottom of the screen frame. Therefore, using this option, you need to be careful.

To make sure that the information is correct, it is best to look at the warranty card or technical passport of the device, if such has been preserved. You can often see how many inches are on the TV on the cover of your passport.

What is the relationship between the diagonal of the screen and the size of the TV? We will answer this question further.

The relationship of the diagonal with the size of the TV

Two points that affect the choice of the diagonal of a TV device:

  • distance from the point of view to the screen;
  • screen resolution.

The relationship between screen resolution and TV size is an indisputable fact. The higher the resolution, the closer the viewpoint can be without loss of quality. Therefore, if the resolution is lower, then the diagonal of the screen (when measured in cm) must be smaller, or it is required to increase the distance between the device and the viewer.

In practice, everyone can check this on their own. When you look closely at a low quality picture (terrestrial TV), all the disadvantages of the picture are immediately visible. If you move away a little, the defects will not be so noticeable.

Let’s look at an example. Take TV 40 “, for a terrestrial signal, the distance to the TV should remain about three 40”. Therefore, we multiply 40 by three, we get 120 ″, translate into centimeters 3.04 cm, at least 3 meters.

If the resolution is 720p, then the distance to TV is allowed at least 1.9 meters. When the model supports Full HD, viewing can be carried out from a distance of 1.3 meters.

That is, from such calculations, you can get the permissible minimum distance to the TV device, depending on the screen size and resolution. Thanks to competent calculation, you can avoid when viewing obvious defects that are associated with the signal structure.

Let’s take another example. Let’s say you plan to view at a distance of 2.2 meters. When purchasing a device with HD Ready resolution, you will have to opt for a model up to 37 ″.

When the resolution is Full HD, the dimensions of the device are allowed up to 52 inches. What’s more, there will be no loss in image quality. If you are using a 4K TV, the distance from the point of view to the screen must be at least 2.2 meters.

If viewing is carried out from a distance exceeding a predetermined value, there will not be a huge difference between TVs with different resolutions. It should be remembered that the signal must also correspond to the resolution of the device itself, this increases the quality of the reproduced content.

As a result, today a large number of models are being released in Full HD and the line is expanding with 4K. At the same time, do not forget that the number of pixels in the video signal should also be taken into account.

625 lines is the resolution of terrestrial TV. Digital TV is gaining momentum in popularity and the resolution will be higher than SD. Many Full HD movies are released, but very little Ultra HD footage.

It is recommended today to carry out all calculations on the condition that you plan to view content with Full HD resolution. Then you will know the minimum distance. If you need to increase the distance, there will be no loss of image quality. This is the most correct decision.

The minimum distance from TV to the viewing point and the size of the TV diagonal are related to the following table:

The table above contains two indicators that allow you to determine the third parameter. Analyze the horizontal values ​​to find the optimal diagonal. The resolution is in a vertical column. When two parameters are connected, the required distance in meters from the TV to the viewing point is formed

720p signal is provided by satellite dishes, digital TV, game consoles. It is better to purchase a TV with Full HD resolution if there is source of this signal. Of course, you can use schematic solutions that increase the signal resolution to this indicator. It should be understood that this method is not capable of providing a constant 100% result.

The “presence effect” of the viewer is the reason why special attention is paid to the diagonal, resolution and position of the TV. That is, exactly how much each user is immersed in the image on the screen. Peripheral vision also affects this effect, and the viewing angle of the picture affects the functioning of this process.

As an example, the following guidelines exist for HDTV:

Angle Viewing distance
20 ° x 2.5
30 ° x 1.6
40 ° x 1.2

The last option is the minimum viewing distance for Full HD TV.

When purchasing a device for the home, you should take into account not only this effect, but also other subtleties caused by restrictions in the installation of TV. As a result, the appropriate distance and the TV diagonal are not linked by 1 value, but a whole range of recommended indicators is indicated.

Most often, for a specific diagonal, manufacturers independently select the optimal viewing angle. If you adhere to these recommendations, then you can make viewing convenient and ensure complete immersion:

  • Maximum from 30 to 40 °;
  • Minimum 10 to 20 °.

As a result, it is recommended to immediately determine for yourself the distance from the viewing point to the screen, on the basis of which you can choose the already optimal resolution and diagonal in centimeters. This will create comfortable conditions for watching any program of the series and other content.

Summing up, we can say that the quality and comfort of watching TV depends on the choice of the diagonal of the TV device. It should be noted that 40-55 inch models are much more expensive than more compact options. Also, such dimensions are not universal, since not all rooms will be able to arrange them according to the rules.

For a standard room, consider a 32-inch or 40-inch TV. It is recommended that you familiarize yourself with the purchase bidders available to you in advance, and then make your final choice. But when choosing a device, do not forget about a number of related factors affecting the picture quality.

How to choose the size of the diagonal

Two factors influence the choice of the TV diagonal:

  • distance. from which you will watch the television receiver;
  • picture resolution. displayed on the screen.

And this picture resolution depends both on the screen you purchased and on the video signal supplied to the TV input.

In the picture you can see how to measure the diagonal of the TV.

You can check this yourself when choosing a TV receiver. If you look closely at a picture with low quality, for example, on-air television, you will notice all the shortcomings of both the image and the video signal processing circuits. And if you step back a little, small errors will become imperceptible.

For example, if you take a 32-inch TV receiver, then for a signal with 625 lines (terrestrial television), the distance to the screen will be about three diagonals 32×3 = 96 inches or 96×2.54 = 243 centimeters, which is approximately 2.5 meters. And if the image resolution corresponds to 720p, then the distance to the screen for normal viewing will already be 1.9 meters or more. If the TV is already Full-HD, then it will be convenient to view the video picture from a distance of 1.3 meters or more. These are the minimum distances to the screen, when viewed from which distortions caused by the structure of the video signal will not be visible in the picture.

For example, if your viewing distance is about 2.2 meters, then when buying an HD Ready TV, you can choose a device with a diagonal of up to 37 inches. If you choose a Full-HD TV, you can increase the diagonal up to 52 inches without sacrificing picture quality. And the new 4K (Ultra HD) models with UHD video conversion will already be over 60 inches at this viewing distance.

For example, one of these TVs: Samsung UE-65NU7400.

65 ” diagonal, 4K resolution, upscaling module that upscales any video to 4K.

UE-65NU7400

But when viewing from a distance that exceeds the calculated one, there will not be much difference between TVs with different resolutions. Do not forget that the video signal must correspond to the resolution of the device itself for the highest quality reproduction. Therefore, when today almost all TVs are Full HD and even models with Ultra HD resolution (4 times more than Full HD) appear, then the number of pixels in the video signal must be taken into account.

Terrestrial television still has SD resolution (625 lines). But digital television is already spreading more and more, and there the resolution needs to be recognized additionally, but it will be larger than SD. There are many films in Full HD quality, but there is very little content with Ultra HD so far. It is possible to advise for today all calculations to be carried out on the condition that you are watching a video with Full HD quality, and you will get the minimum viewing distance. And if you need to increase the distance, for example, installing a TV in the living room, then you will not see any damage to the picture quality.

An example of a modern (2018) TV with Full HD resolution: LG 43LK5900.

TV screen diagonal

The diagonal of the TV plays an important role when choosing a TV receiver. The comfort of watching video on the screen depends on the correct choice of the screen size. And it is completely wrong to say that the larger the diagonal of the TV in cm, the better.

How much will it be if you convert 1 inch to cm? As you know, 1 inch equals 2.54 centimeters. Inch (from the Dutch. Duim. thumb) is the name for the unit of measurement of distance in European non-metric systems of measures. Today, an inch is most often understood as an English inch (English inch), equal to 2.54 cm exactly.

  • 1inch = 2.54cm = 25.4mm
  • 1cm = 0.3937inch
  • 1 m = 39.37 inches

In English units, 1 inch = 12 lines = 72 points = 1/12 feet = 1/36 yard.

After the adoption of the international system of units of measurement SI, inches are considered an obsolete designation, which should be gradually phased out. But, despite this, inches continue to be used in engineering when specifying calibers and form factors, for compatibility with long-established technical solutions. In this case, a double prime (quotation mark “) is used as an inch sign.

In television technology, inches is the diagonal of the screen, which is measured as the distance between opposite corners of the matrix. For example, 37 “means a screen with a diagonal of 37 inches or 37×2.54 = 93.98 cm.

Simple length converter to convert inches to centimeters and cm to inches:

For example, if you take a 32-inch TV, how much will it be in cm? Using the calculations in the converter, we get that 32 inches in centimeters will be 81.3. Another example, converting 22 inches to cm, we get 55.9 centimeters. And if we take a diagonal of 42 inches, we get 106.7 centimeters.

Diagonal of the TV in cm table

The minimum viewing distance of the TV and the size of the screen diagonal can be related to the following table:

The diagonals of TVs are presented in inches and centimeters, the table makes it possible to choose the third one by two parameters. In the table, choose the horizontal size of the diagonal of the screen, vertically choose the video resolution on the screen (it depends on both the TV and the signal at the input), and at the intersection of these values ​​there will be the desired viewing distance in meters.

A signal with 720p quality can be output by satellite TV programs, games from consoles, copies of BD discs, digital TV.

1080p resolution corresponds to Full-HD TVs and it is better to use such devices if you have such signal sources. Although there are circuit solutions for increasing the signal resolution to 1080p, such circuits do not always work perfectly. Everything needs to be checked on the spot.

Therefore, it is better to decide on the distance to the screen in advance and, accordingly, select the desired resolution and TV diagonal in cm for comfortable viewing.

READ  Redmi Phone Screen Not Working

In the following table, the width and height are given specifically for the screen, and not for the entire TV. To find out the size of the TV, you need to add the dimensions of the frame around the screen. In modern television sets, the frame is very thin and can be in the range from a few centimeters to several millimeters.

The English inch or imperial inch (eng. Inch from lat. Uncia. 1/12 part) since 1958 equals exactly 2.54 cm. An inch is usually indicated by two strokes “, in English-speaking countries there may also be a designation in from the word inch. Russian letter designation inch no.

Centimeter (cm, cm;) is a unit of length in various metric systems of measures, equal to 0.01 meters. 1 cm ≈ 0.3937 inches.

How to find out the power consumption of your TV

Today, almost no one can imagine life without a “blue screen”: this technique shares the events taking place in the world, teaches, relaxes and can even help surf the web. However, not all of us think about how much electricity a TV consumes. But this is a significant item of expenses.

Energy efficiency class

Energy efficiency is a measure of the ratio of the consumption of a particular model to the average values. The approved standard for televisions was adopted in 2009 by a special commission of the European Union. Classes are marked with letters from “A” to “G”, where “A” is the low flow rate, “G” is the maximum.

It is important to understand that a certain class is not the same for different devices. In particular, for TVs with a diagonal of 32 and 40 inches, the values ​​will be different.

The calculation takes into account, among other things, the screen size. In addition, the values ​​are given for ideal conditions. with certain settings for brightness, color and without connected peripherals, which can also increase consumption.

Previously, energy efficiency was indicated only in the instructions for the device, but in the Russian Federation a law was passed on the need to place special stickers on equipment with an indication of the energy efficiency class, annual consumption, manufacturer’s name, model, and TV size.

Liquid crystal

LCD TVs are much more economical compared to plasma. But the size of the diagonal is of great importance for the power of the TV, which should not be forgotten when choosing the size of the device.

  • At rates up to 32 inches, it will be approximately 40 to 55 watts per hour and only 1 watts pending.
  • A screen of about 49 inches will take 100-150 W / h and up to 22.72 kW per month.
  • The LED version will take another 40% less thanks to the use of diodes in the backlight.

Thus, LCD TVs appear to be the most energy efficient. But you can save money, knowing other criteria.

How to find out the power consumption of your TV

Information about the power consumption of the TV model can be found, of course, in the document accompanying it. the technical data sheet. Compilers usually provide information on how much the device consumes at its maximum power mode and during standby. If suddenly the instructions for the technique are lost, then the necessary information can be found on the Internet, you just need to know the exact model of your TV.

You can also make independent measurements, but for this you need to have special tools at hand. The power of the TV will be shown by a wattmeter, which will determine this indicator almost instantly.

Calculations for different types of TVs may indicate that completely different numbers will be consumed. Knowing this may well influence the decision to purchase a particular model of the device.

Plasma

Such panels will be of interest for a super picture in terms of color rendition and saturation, but in terms of energy efficiency they are far from ideal. If we take different modes of operation, then we get 150-190 W / hour in operation and 0.5 W while waiting. 24.36-28.86 kilowatts come out per month.

What determines the power consumption of TV

The most important parameter is the size and type of the screen: the larger it is, the higher the electricity consumption. A modern LED TV with a diagonal of 43 inches spends about 18 W / h when switched on. However, this is not the only factor. Among others:

  • chromaticity;
  • white balance;
  • working time included;
  • sleep time.

Often users forget that in standby mode, the device also consumes power, but much less. On average, consumption is about 0.5 W / h. LED TVs have a modest electricity consumption, but older equipment with LCD or CRT panels has several times higher consumption than the above values.

With a cathode ray tube

Almost all of us grew up with such TV sets. these are bulky models that have a kinescope. They are unpretentious in operation, have a long service life, but cannot boast of energy savings, because their consumption is 60-100 W per hour. For a day, the amount of at least 0.5 kW comes out, and in a month the figure rises to 15. In standby mode (that is, around the clock), the indicator in watts will be equal to 2-3 units. Total for the month. from 16 to 18 kW.

What is the power consumption of the TV?

A modern person cannot imagine his life without watching TV. This helps relieve stress after work. TV is made for entertainment or learning aid. But few people thought about how much electricity the device can take. The power of the TV depends on its model and type. How much does the TV consume electricity per hour or month? Let’s figure it out in the article.

CRT TVs

These are well-known bulky models with a picture tube. Among their advantages is an extremely long service life, so they are still preserved in some families. But such TV sets cannot please with their efficiency. They consume 60 to 100 watts per hour. That is, in the worst case, we can consume 0.5 kW in one day. A month of TV viewing will result in 15 kW. To this add around the clock consumption of 2-3 W per hour in standby mode. Total 16.44-17.16 kW per month.

Types of TV and their power

Full information on the power consumption of a particular model can be found in the technical data sheet of the equipment. Manufacturers provide this information because it allows customers to immediately know the maximum power consumption of the TV.

It is also possible to get information about energy consumption when the TV is in standby mode. But if the instruction is lost or it has deteriorated for a number of reasons, then the information can also be found on the Internet if you know exactly the code of your TV.

All necessary data is printed on the back of the purchased device. To get acquainted with information about TV power, you need to go to the manufacturer’s official website and enter the found code in the search bar. After that, the user will be redirected to a page where all the characteristics of the device are accurately described.

If this method is not suitable, then you can make measurements yourself, but for this you will need to have some tools on hand. You can find out the power using a wattmeter, which determines the indicator in a few seconds.

It is important to understand that the power consumption of different types of TVs depends not only on the device itself, but also on the time it works during the day.

General information

Information about the energy consumption of the TV model can be found, of course, in the document accompanying it. the technical data sheet. Compilers usually provide information on how much the device consumes at its maximum power mode and during standby. If suddenly the instructions for the technique are lost, then the necessary information can be found on the Internet, you just need to know the exact model of your TV.

You can also make independent measurements, but for this you need to have special tools at hand. The power of the TV will be shown by a wattmeter, which will determine this indicator almost instantly.

Calculations for different types of TVs may indicate that completely different numbers will be consumed. Knowing this may well influence the decision to purchase a particular model of the device.

Cathode-ray tube

A television with a picture tube is technically and morally outdated. It is bulky, the principle of operation is based on old technologies, but its service life is calculated in decades. Such a TV set consumes at least 100 W / h. Electricity consumption reaches 0.5 kW per day, at least 18 kW per month.

How much electricity does the TV consume

The use of advanced principles of image projection, modern devices processing the flow of information, have significantly reduced the dimensions of devices and reduced the rate of consumption of electrical energy.

Consumption calculations in standby and working

Let’s take a look at the three most popular types of TVs. When calculating, you need to take into account the consumption of the device in standby mode, the table below shows the dependence of electricity consumption on the type:

The smallest consumption of the first type of TV with the letter “A”, the largest consumption of the type with the beech “G”. Therefore, when choosing a TV, you need to pay attention to this.!

For calculations, you need to know: what type of TV and its power. The power can be found in the characteristics on the packaging or on the back of the TV, the value that we need is highlighted in a red rectangle. The power is written: W or W. In the case found, it is equal to 137 W.

How to determine how much a TV consumes

If 1 kW of energy costs 4 rubles, then TV will “eat” 96 kopecks per day. A month. 28 rubles and 80 kopecks. You will have to spend 345 rubles per year.

The average power consumption of the TV during operation is 100 watts. Although this also depends on the specific model. You will have to pay attention to the size of the diagonal. If we take the average parameters of each device, then in most cases it is the computer that “eats” more.
