Determine the size of the monitor screen in inches. Screen diagonal and viewing angle

The sizes of screens and TVs in inches and centimeters

What size of the TV will fit on my shelf? A 32-inch TV or a large 55-inch TV will fit there too? With the help of our table of the size of TVs, depending on the diagonal presented below, you will easily get the answer!

The dimensions of TVs are usually indicated in accordance with the screen diameter, which is equal to the length of the screen diagonal. This is the distance between the opposite angular points of the screen.The optimal size of the TV depends not only on the length of the screen diagonal. To find a TV of a suitable size for your home, you also need to take into account such order factors as the size of the room, the size of the niche for TV on the wall, and even the distance from the screen to the sofa.

The sizes of screens and TVs in inches

If you plan to buy a new TV, you should definitely choose a device with a ratio of the parties 16: 9, which is currently used by most TVs with a flat screen.The viewing angle remains an important factor for three.dimensional television. A real three.dimensional image is possible only at an angle of about 75 degrees.

Tips for choosing a TV in a store

The fact that the TV looks smaller in the store, and when you bring it home, it turns out to be more expected. The reason for this is that the stores have a huge space, much larger than the apartment, and it is difficult for you to evaluate the real size of the TV compared to your room. Therefore, people often purchase televisions of much larger size than what is suitable for their home, especially if you take into account factors such as the recruited distance between TV and sofa.

With the development of HD-TVs with a high resolution, buying a larger device than previously expected, has ceased to be such a big problem, the more more and more television stations and cable networks are still broadcasting their programs in HD quality.

Party ratio or screen format

Speaking about the size of TVs, first of all, the screen format should be taken into account. This applies to the so.called ratio of the parties, which is the ratio of the width to the height. The old TV screens had a “square” ratio of the parties 4: 3, but today less and fewer broadcasting means are broadcast in this format.

Format 16: 9 is currently used for flat screens. If 4: 3 programs are visible on such devices, a black strip appears along the edges of each side edge of the image. However, films and programs in 16: 9 format can hardly watch normally on the device 4: 3. In such cases, the main components of the image, as a rule, are not displayed on the display, and the image shown by the device looks only as an excerpt. So, if you plan to buy a new TV, you should definitely choose a device with the format of the parties to 16: 9.

A special format for real widespread television is 21: 9, also known as a movie format. However, these devices are suitable only for a real home theater with content 21: 9. For programs in format 16: 9, either the image is distorted, or on the left and right, black stripes are displayed.

What is the diagonal of the monitor is measured

The monitor is a device that is designed to lay out information in a text or graphic mode. often it is used to display data on the screen.

Find out what the display diagonal is measured in. Inch is the unit of measurement unit. Translated to centimeters, the value is 2.54.

The diagonal of the computer monitor

The following monitor indicators are most common:

• Computer screen. 17 ″, 19 ″, 21 ″, 23 ″ (inches);
• TV. 32 ″, 43 ″, 49 ″, 50 ″, 55 ″, 65 ″ (inches);
• smartphone, mobile phone, tablet. 4 ″, 3.5 ″, 5 ″, 5.5 ″ (inches);
• laptop monitor. 13.3 ″, 15.6 ″, 17 ″, 19 ″ (inches).

Some developers show cunning when one of the listed indicators indicates on a large label, and in small letters they introduce an amendment, as a rule, in a smaller way, not in favor of the buyer. This is carried out deliberately to save money and reduce production costs for the development of technology.

We present the most common indicators in terms of centimeters:

Computer or laptop monitor parameters

How to determine how many inches monitor

There are several options for determining the diagonal of the display. The first two of them are very simple, and for those who are not looking for easy ways, you can recall the school geometry course and solve a little.

Manual method of measurement

This method of determining the diagonal of the monitor is very simple. To do this, prepare a ruler either a centimeter tape, attach it neatly to the screen of the TV, or the laptop diagonally and measure. The resulting value in centimeters should be divided into a value of 2.54. this will be the size in inches.

View documentation

When buying any equipment, a package of documents is attached to it, which indicates all the necessary information. In order to find out how many inches the display of your computer or TV, you should see the data about this in the attached documents.

If for some reason you do not have this package of documents, then find out how length the monitor is, you can look at the label with the name of the model and other information on the laptop body or on the outside of the TV. Basically, the screen resolution is indicated by two digits in the letter designation or in the first line of the characteristic. For example, the indicated model of the laptop L1702, respectively, the diagonal is 17 “.

REFERENCE! To determine the diagonal of the display of your computer, laptop or TV, you can use the Internet. To do this, in the search engine you only need to enter the model and brand of your device.

Using specialized programs

You can also determine the size of the display using specialized programs such as AIDA64, Sisoft Sandra, etc. Having entered the program menu, select the “Display” item, then, opposite the “Monitor” item, the desired parameter will be shown.

These programs give out values ​​that are laid down in their database, therefore, if the characteristics are displayed incorrectly or completely absent, it is recommended to establish a new version.

Other ways to determine the diagonal of the monitor

A non.standard option for determining the size of the diagonal is its mathematical calculation using the Pythagoras Theorem “On the sum of the squares of the legs”. To solve this problem, it is necessary to measure the length and height of the monitor, build each of the values ​​in a square and fold their values. From the resulting result in centimeters, remove the square root and divide it into a value of 2.54. So the size of the calculated length in inches is ready.

You can also measure this monitor using a laser device for measuring the distance, curvimeter. a device for determining the length of winding lines consisting of a gear roller and counter.

Threat translation into centimeters

It’s no secret that the above parameter is in inches. Many users may have a question: why not indicate the diagonal of the screen in centimeters. Firstly, you should know that inch is a non-metric system, and in the metric is used.

In modern, this unit is practically not used in everyday life, exceptions are separate industrial industries, for example, the production and sale of televisions. The measurement in inches is due to the fact that the first TV appeared in the United States, where a non.metric system is used.

Many more may interest: why they do not use the length and width of the screen, instead of a diagonal. The fact is that manufacturers produce modern TVs only with a standard ratio of length and width (4: 3, you can still find 16: 9).

Reference! Because of this, only one value is enough-the diagonal of the screen.

In general, if you take from history, inch is equal to the distance of the far phalanx of the big finger of a person. If you translate into a more familiar to the system, then 1 inch = 2.54 centimeters or 25 millimeters. Accordingly, to count in centimeters, you need to multiply the number of inches by 2.54.

How to find out the diagonal of a computer monitor

There are several quite common reasons to determine the size:

• Curiosity. you most likely wanted to know more about reading articles about your display;
• Buying. you need to purchase a monitor or laptop. And maybe the size is of great importance for you. And there are several models in front of you, and you need to unsatisfying the best product for less money. This is especially important for a gaming laptop;
• Repair. you need to choose a new matrix for your laptop. And of course it is necessary to accurately determine its size.

Manual measurement of the diagonal

• Take a ruler, roulette, or measuring tape.
• Measure the distance between the upper left and right lower angle of the monitor.
• The value in centimeters translate into inches.

Please note that you need to measure the visible part of the screen. And the size of the case in the calculations does not take into account.

Using special programs

In any of these programs, find the item “Monitor”, “displays” or similar ones among the equipment list. And then among the parameters find the item “Resolution”.

Software takes this item from its database. So the information may not be true. Because your monitor may not be in the database of the program.

How to find out the diagonal of the monitor using documentation

All the parameters of the device are most likely indicated in its technical passport. And all the information you need should be sought in the section that is dedicated to the technical characteristics.

Search system (Google to help)

Most likely knowing the brand of computer monitor, you can find all the information about it on the Internet. This information is located in the descriptions of the goods of the online store, as well as on the manufacturer’s website. But be especially attentive. Since in different stores information about your device may vary. Sometimes sellers even write numbers from the air, and also use unverified data.

But on the manufacturer’s website, the numbers should be accurate. But they do not always have a Russian.speaking inteeeice. And when measuring parameters, different methods can be used. In addition, manufacturers can indicate the diagonal of the screen taking into account the case, improving this for the size of the visible area.

Factory sticker on the monitor case

Most often, a sticker is located on the rear wall of the case where the serial number is indicated. As well as the manufacturer, operating conditions, release date and model name. Sometimes the diagonal of the screen is indicated directly. If not, then find the name of the model. Most likely the first two digits. this is the value we need.

So, LG Flatron E 2260 diagonal is 22 ″. And if you doubt the result, you can check with other methods. For example, on the manufacturer’s website or independent measurement.

How to find out the diagonal of the monitor by mathematical solutions

Now it’s time to remember the geometry. And as we all know from the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the legs. In our case, the hypotenuse will be the diagonal of the monitor. And legs. the width and height of the matrix. Therefore, we build a vertical and horizontal screen in a square. And then we will summarize them. And to calculate the diagonal, from the resulting value we remove the root.

For example: the dimensions of our monitor 10.5 ″ × 19 ″. We learn the square of its hypotenuse: 10.5² 19² = 110.25 361 = 471.25. Now we calculate the diagonal itself: √471.25 = 21.7 ″.

This method is most likely the most accurate. It allows you to find out the real dimensions of the visible part of the screen. And pay attention. measure only the matrix, t.e., display without taking into account the case.

Other methods of measurement

You can bring a few more exotic ways to measure the diagonal of the screen.

• Comparison with the standard. take for comparison an object whose dimensions are already known to you;
• Laser rangefinder. it will determine the size with an accuracy to a fraction of a millimeter;
• Courvimeter. here, to measure the distance, draw a wheel on the measured surface. But be careful. this can damage the matrix.

Method 1. according to the monitor model

Determining the monitor model is very simple. It will be written in one of two places. or on the front frame around the screen or on the back of the monitor.

After you determined the model of your monitor, we open any search engine and enter this very model there.

We collect the found monitor model in Yandex

We open the first few sites from the opened search results and read the description of the monitor. One of the first lines will be precisely the size indicated in the inches.

To find out how much it is in centimeters, just multiply the indicated number by 2.54 and you will learn the diagonal of the monitor in centimeters.

Method 2. making measurements

Give the answer to the question “How to find out how many inches monitor?”You can in another simple and at the same time in an efficient way. by measuring a ruler or roulette the distance from the opposite peaks of the monitor screen (diagonally).

In order to find out how many inches monitor, then the number obtained when measurements or roulette must be divided into 2.54.

Monitor diagonal measurement of the diagonal roulette

For example, when measurements by the ruler diagonally, the screen size turned out to be 48.3 cm. We divide this figure by 2.54 and get 19.01. We round to the whole part and get the number 19.

Find out the resolution of your screen using DirectX diagnostics tools (for all Windows versions)

For this method, it does not matter which version of Windows you have installed, so you can always use DirectX diagnostics tools to obtain your screen resolution. Open the “Launch” program, command line or PowerShell. In any of these programs, enter the DXDIAG command and click Enter on the keyboard.

Entering the DXDIAG command into the command line

In the DirectX diagnostics tools, select the “screen” tab and scroll the “device” list yet you will not find the field with the name “Current screen resolution”. Its value is the current resolution of your screen. Using an example below, you can see that our monitor has a screen resolution 1366 × 768 pixels.

The “screen” tab and the “Current screen resolution” field

Find out the resolution of your screen using the System Information application (for all Windows versions)

You can also find out the resolution of your screen in the “System Information” application. Open this application using a command line.

Entering the command to call the application “System Information”

In it, open the list of “components” on the left side of the window and select the “screen” or “display”. Scroll through the right side of the window until you see the “resolution” element. Its value will be a resolution of your screen. For example, you can see the resolution of our screen. 1920 × 1080 pixels.

How to find out the diagonal of the monitor

Good day friends. Today, I will tell you how to find out the diagonal of the monitor in a few available and understandable ways to all. On the one hand, this is a trifle question, but on the other, I personally heard from my friends and friends more than once about a request by determining the diagonal of a computer or laptop monitor. Therefore, I decided to tell in this article more and more in detail so that you do not have such questions anymore.

The very first way to determine the diagonal will be simple to disgrace. And it consists in the inspection of the documentation that is attached to your monitor. Carefully inspect it, and I can give you almost a 100% guarantee that, in addition to the model of the monitor itself, its diagonal will be indicated.

If you bought a monitor in a used state, or just threw the documentation to it, then we miss this step and go to the second point.

In the most thorough way, inspect on the top of your monitor, and especially its corners and inscription in the middle of the lower bar, often the manufacturer marks its products and indicates the diagonal immediately after the letter designation in the form of 2-cyfries.

If there are no inscriptions on the front panel of the monitor or they are lost, then carefully inspect the back, there is almost always an information sticker.

We go to Yandex.Market in the Computers section. monitors and in the search bar we enter the model of your monitor. Click the button to find and in the search results look at the technical characteristics of the device.

Typically, the type of monitor and its diagonal are in the first lines of characteristics.

In my opinion, the most faithful and time.tested way. If you do not have documentation for the monitor, there are no stickers and signs on the device itself, and Yandex.The market does not seek your model, the only 100% option for determining the diagonal of the monitor is its measurement, a regular ruler or roulette.

Pick up a ruler (more conveniently roulette) and from the lower left corner of the monitor, measure the distance to the right upper corner (you can and vice versa). Divide the result in centimeters by 2.54.

The ruler from the lower left corner on the right upper one will show in centimeters, if you need in inches, just divide 2.54 centimeters, since 1 inch = 2.54 cm.

In inches. 58/2.54 = 22.83, that is, my 23 inches.

That’s all friends. How to find out the diagonal of the monitor you already know for sure, so share information with other users, you need to help everyone.

How to find out how many inches a computer or laptop monitor?

I welcome everyone on our lamp portal Wifigid.Ru. Today I will tell you how to find out the diagonal of a computer monitor or laptop screen. I will sign a few simple ways that should help you. As you know, inches are used to measure. To roughly imagine the size, they are best to change them to our favorite and native centimeters:

Very often the manufacturer indicates inch in the name of the model of the monitor, or laptop. For example, the AOC Q27G2S/EU model has a 27.inch diagonal. Or LG 27MP400-B-has the same diagonal. To see the name, you can look at a special label. It is usually glued on the back of the monitor. If you have a more old model, then the sticker can be glued in front.

If you have a monitor from the Chinese company Xiaomi or Huawei, then such a figure most likely will not be. Another feature of the monitors. the figure in the name is always rounded. For example, the AOC 24B2xDM model. actually has a diagonal of 23.8 inches. And the screen LG Ultragear 32GN600-B-has a diagonal 31.5.

The laptops are a little different. Yes, in the name you can often find the size of the diagonal, but there is no rounding there. So laptop Lenovo Ideapad Gaming 3 15IMH05. has a diagonal of 15.6. And the HP OMEN 16-C0007UR model-16.1. The name of the laptop can be viewed on the same label. it is usually sculpted at the bottom of the apparatus or on the front next to the keyboard. There you can also see the size of the diagonal.

In laptops, you can meet with the same problem. not always in the name of the model there is a diagonal size. In any case, the name can still be useful to us. we can simply take and google this information. Just open any search engine and drive the full name of the model in the search line. After that, go to any store, to the official page or look at the review. there will be information about the diagonal.

HELP! If you cannot find a diagonal yourself. just write in the Комментарии и мнения владельцев the exact model of your monitor or laptop, and I will answer you immediately.

Measurement

Another simple option is just to measure the diagonal of the monitor or screen. Even if you have some kind of error at the same time, it will still be minimal. Any line or even a soft “centimeter” is suitable for this. For measurement, we will use two opposite angles that are diagonally. After that, you need to divide the resulting number by 2.54. Let me remind you that the diagonal may have a non.exact figure. for example, diagonals 17.3 or 16.1 inches.

Documentation

Another option of how to find out the diagonal of the laptop is the study of the documentation that is coming in the kit. On the page of the technical characteristics of the device, the size of the display is mandatory. At the same time, it is likely that the figure will be accurate.

If you could not find the value in the papers, you should at least write out the monitor model. It is usually printed on the cover. Knowing the model, you can use the search engine to find the laptop parameters. The most accurate information will be provided by the official site of the manufacturer. Third.party resources pay much less attention to the veracity of the published data, so there is a chance of error.

Using special programs

In search of the size of the laptop screen or a stationary computer, programs that display detailed information about the system will help. A vivid example is “AIDA64”. you can download and install from the official website of the developers. The program is paid, but has a test period, which will be enough to obtain the necessary information.

After starting, you should go to the section “total information” and pay attention to the right side of the window. Next, find the “display” column, in the “Monitor” line will be the desired value in inches (indicated by the sign “” ”). Here you can see the screen model and the type of matrix.
