Largest screen extension. How to adjust resolution

All tips

IN modern world everything is changing rapidly. Cameras of all models, from the cheapest point-and-shoot cameras to professional DSLRs, can shoot HD quality videos. This video is also possible for expensive models mobile phones. DVD video standards are a thing of the past.

Film studios are making new spectacular films with previously unavailable effects. The requirements for video and television equipment standards are also growing. Viewers want films shot in higher quality images - they want to view them on wide screens, not just on a computer monitor.

What is screen resolution TV 1920x1080

Screen resolution is what affects the clarity of the image. This is the quality of the pictures and text messages. Unit of measurement of resolution - responsible for the formation of the image on the screen. Today, when purchasing a TV with a plasma or LCD screen, you will probably come across the term Full HD - 1920x1080, which the seller will definitely tell you about.

These TVs are now in everyone big store, they are affordable, which is what buyers are looking for now. If you answer that you do not know this term, the seller will add that this sign is best recommendation for a TV, and a resolution of 1920x1080 is an indicator high quality images.

How to choose a TV

When you are choosing a TV, pay attention to the measurements measured in inches. One inch is about two and a half centimeters. But monitors with big screen demanding on the video card. That is, if you bought a modern twenty-four-inch diagonal monitor, then expect that your iron horse will slow down slightly.

Budget 18-19 inch monitors are only good for their price. And for those who love battle scenes on big screen, monitors with 27 inches diagonal are suitable.

Some people are now wondering why modern monitors so narrow and elongated. There is an explanation for this. For modern films there are standards for the shooting format. They are filmed like this, with an elongated and narrow image. If you watch a new movie or play a modern game on an old square-shaped monitor, the picture will be small, and not everyone will like it.

FullHD or HD Ready

On the packaging boxes of TVs, in addition to the FullHD inscriptions, you often find other inscriptions - HD Ready.

What's the difference?

In 2005, the European Association of Telecommunications Technologies and Information Systems adopted standards for new TV models that will display video with high quality parameters. They are divided into two categories: HD Ready and FullHD.

HD Ready supports the minimum resolution for this class - 720 lines, and FullHD, where the screen resolution is 1920x1080, is capable of handling video with 1080 lines.

This name was picked up by the Japanese company Sony when, in 2007, it named a number of its products as the FullHD brand. Other companies in this market segment began to call their products the same way.

Therefore, most of the liquid crystal and plasma television receivers of the FullHD class sold nowadays (translated from English as “ full resolution 1920x1080") screens have a screen aspect ratio of 16 by 9 and support videos with 1080 lines of image. Such images compare favorably in quality to a simple DVD; they are clearer and of higher quality.

So what is screen resolution, how do screen settings affect the picture we see on the monitor?

The TV screen, whatever it may be, plasma or liquid crystal, is a matrix that consists of pixels located horizontally and vertically of the screen. Their number is called matrix resolution. Screen resolution comes in many types, but the most famous ones are 1024x768, 1366x768, and many others.

Types of television signals

The highest resolution now is Full HD - 1920x1080.

Television signals also have a resolution that has not yet reached a common standard throughout the world. In the USA, for example, the type is called NTSC (with a resolution of 640 by 480 pixels). In European countries, PAL signals and SECAM signals with a resolution of 720 by 576 pixels are used.

The signal may also differ in frame rate: fifty or sixty hertz.

In every modern TV there is a processor that converts incoming signals to the standard that the TV matrix corresponds to. If the incoming signal and matrix were with one standard definition by pixels, the image would immediately be clear and of high quality. But, since signal standards are different in types, parameters and matrices, the TV must independently convert the signal in order to show a clear image.

Progressive and interlace scanning

The range in which TV channels broadcast is small. There is not enough space for everyone. The image transmitted by the channel can be formed in two ways. Progressive, which displays all frames completely (where the lines - even and odd - follow one another), and interlaced.

To save space on air, a scan was invented that reduces the frame rate by half. It was called interlaced. First, the first half of the frame is transmitted in odd lines, then the second half in even lines. Interlaced scanning would look blurry if there was no way to restore image quality.

In order to explain the method that forms the image, after the number of lines the initial English is written: “p” or “i”. For example: a resolution of 1920 x 1080p indicates that the picture was generated in a progressive way. And the 720i marking will mean that the video has 720 lines. And the letter i stands for the interlaced method. In order to indicate the format, the second-by-second frame size is indicated. When they say 1080p30, this means that there are thirty frames in this video, running per second. The higher the number of frames, the better and more detailed the picture looks.

Full HD requirements

TVs last generations display images of both scan types. Thus, a screen resolution of 1920x1080 and an aspect ratio of 16:9 must be present in Full HD TV. These are the standard requirements for this type to display the incoming video signal.

Therefore, a resolution of 1920x1080 would mean that the TV has 1920 horizontal dots and 1080 vertical dots. Such TVs will catch high quality signals accepted in the world (HDTV standards).

Tricolor TV, a commercial TV operator, has been offering a package since 2012 that includes twenty-five HD quality channels. Someday, such channels may be free for everyone.

If you have problems with your monitor, font or image is not clear, you need to understand that this changes due to the resolution value. Let's say, when the resolution is set to a high value, say 1920x1080, then objects will be clear. And a larger number of them will fit on the monitor. And with a low resolution, say 800 by 600, fewer objects will fit on the monitor, but they will look larger.

But this does not mean that you can set the screen resolution you like to 1920x1080. It may not be supported by your monitor or TV model. CRT monitors support a resolution of 1024 by 768 pixels or 800 by 600 and are suitable for all types. LCD monitors and laptop screens support high resolution. And they work with the look that is suitable only for their model.

Monitor large size corresponds to the same high resolution. It improves clarity and reduces image size.

How to adjust monitor resolution in Windows 7

To do this, you need to go to the "Start" menu, then go to the "Control Panel", and then go to "Appearance" and "Personalization". Then go to the “Resolution Settings” of the monitor. Now expand the list next to “Resolution”, use the slider to set the resolution you need, then click the “Apply screen settings” button.

Late models of monitors, on liquid crystals, work with own resolution. It does not need to be configured - it is already recommended for this type. Such monitors are divided into two types: with a ratio of 16:9 and 16:10 and standard with a ratio of 4:3. If you compare them, widescreen has a larger width and horizontal resolution.

If you don’t know the monitor resolution, you can find it out from the reference book, on the manufacturer’s website, or from the EDID.

What is EDID

There is a data standard that provides information about the monitor and its parameters, where it is made, its resolution, size, color quality characteristics, and so on.

If you can’t find out by EDID, then how to set the screen resolution

What should you do if, when you connect a TV receiver with a large screen, the image does not fit and looks cut off at the edges? To solve the problem, you need to update your computer's video card drivers. After this, specify your model in the computer settings as the base, or main monitor. Then you need to make sure that the TV is connected to the computer via a digital connection, and also that there are no restrictions on it.

Install the Moninfo EDID program (it is available on the Internet). After that, check the resolution of your TV in it. If it is supported, that's good. If not, then you will have to edit the EDID and set the resolution yourself.

If the image does not fit

To deal with this problem, you need to turn off the Overscan option on your television receiver.

If this is a computer, then after the obligatory video card you need to click right click mouse on the desktop. If you have GeForce video card, then after that go to settings NVIDIA programs. If you have Radeon video card, then go to the Catalyst program Control Center. Then adjust the parameters using the slider in the “desktop” settings to the required value.

How to adjust resolution

First you need to disable EDID.

Then set the resolution to 1920x1080 in the screen properties.

Reinstall the video card driver (remove the old driver).

If the previous measures did not help, try reinstalling Windows.

I would like to hope that after this information, questions about how to set the screen resolution to 1920x1080 will be easier to resolve.

What is screen resolution, what types exist and how do they differ.

Screen resolution is one of the most important characteristics that every person who wants to buy an LCD TV in a store should take into account. household appliances. Resolution, which undoubtedly affects cost, is measured in pixels. The resolution designation is the ratio of the number of vertical pixels to horizontal pixels. Modern manufacturers invest huge amounts of money in the development of LCD TVs, whose screens would have the highest possible resolution.

Note that the manufacturer of the TV will not necessarily be the manufacturer of liquid crystal matrices. Different companies can purchase screens from the same manufacturing company, as a result of which we can observe the same matrices in different models.

Standardization

Of course, manufacturing companies must coordinate developments in terms of increasing the resolution of matrices. This is the only way to achieve stable operation television broadcasting in all regions. This, in turn, allows manufacturers to sell their products in different countries. To this end, international organizations have developed specialized standards for the development of technologies for television. high definition, and these standards are mandatory for all manufacturers and developers.

Permissions modern models TVs

Standards for high-definition television were developed by the European international organization ETSI and the American international organization ATSC. In accordance with these standards, which allow TVs based on LCD technology to be compatible with all international regions, the following resolutions of LCD TVs are distinguished:

1. 720 rub. A standard for a resolution of 1280*720 pixels, characterized by an aspect ratio of 16:9, frame rates of 50 and 60 Hz, and progressive scan.

2. 1080i. Standard for 1920*1080 pixel resolution, 16:9 aspect ratio, interlaced scanning, and frame rates of 25 and 30 frames per second.

3. 1080r. Standard for 1920*1080 resolution with frame rates from 24 to 60 Hz, 16:9 aspect ratio and progressive scan.

Main Differences

As you understand, modern standard decompositions TV signal for different countries were created in an effort to achieve maximum image quality when transmitting a signal over a distance. The main characteristics of signal decomposition are the type of frame scanning, frame frequency and number of lines.

Among the main television standards For television signal transmission, the European standards PAL/SECAM can be particularly highlighted. Valid in the USA NTSC standard. The European standard provides 625 lines, and the American standard provides 100 lines less. It is necessary to take into account that the standards were developed even when the first CRT televisions for mass consumption appeared. For example, on CRT TVs All 625 lines of the generated image are not used. In a system of deflecting coils, it is necessary to provide not only the time during which the beam travels to the source, but also the reverse time of the beam's movement, so the visible frame is actually formed from only 576 lines. This fact formed the basis for standardized permission for digital television, whose value is 720*576.

If we talk about the frame rate, then for old television receivers it was determined by the frequency of the current in the electrical network of a certain region. So, in America the frequency of the current was 60 Hz, while in Europe it was 50 Hz. This fact greatly facilitated the work on creating television scan generators.

Despite the fact that the standards were developed a long time ago, they are still adhered to today, since new TVs must be compatible with older models. For digital television receivers, that is, for LCD and plasma televisions, no restrictions are required, which is explained by certain design features. So, new standard HDTV, designed for high-definition television, is based solely on digital transmission of television signals. To create service pulses, it does not need to use lines, as a result of which the number of lines in the name of the standard determines the number of lines forming the image. The HDTV standard can be generated with 720 or 1080 lines, with progressive or interlaced scanning and frame rates of 50 and 60 Hz.

Standards are indicated by a record that specifies the number of signal lines, interlaced (i) or progressive (p) scanning, as well as the frame rate, which can be written separated by a slash.

Interlace scanning - preliminary updating of even lines with subsequent updating of odd lines in another half-frame. Progressive scan – recording all lines of an image on one screen simultaneously. As you can imagine, progressive scan produces higher quality images.

The following types of television signal decomposition are distinguished, which have been used since the beginning of the development of modern television:

1. Low-definition television LDTV, standard 240p and 288p;
2. Standard definition television SDTV, standard 576i for PAL and 480i for NTSC;
3. High definition television EDTV, standards 480p, 576p and 720p;
4. High-definition television HDTV, 1080i and 1080p standards;
5. Ultra high definition television UHDTV, standard 4320p.

Screen resolution is very important characteristic TV. Manufacturers are investing a lot of money in developing high-resolution screens. Such developments are expensive and not all TV manufacturers are also manufacturers of LCD matrices. Many of them buy screens from companies that have been producing LCD matrices for a long time, and then use them in their TVs.

Screen resolution is measured in pixels and denoted as the ratio of the number of horizontal pixels to the number of vertical pixels.

For normal operation TV broadcasting in different regions and, accordingly, the ability to sell their TVs in different countries requires manufacturing companies to coordinate their developments in the field of increasing screen resolution. Therefore, international organizations have agreed on various developments in the field of high-definition television, and today there are several standards that everyone adheres to.

Resolution Formats

Today, international organizations, such as the American ATSC and the European ETSI, have defined standards for the distribution of high-definition television. And TV manufacturers have introduced these standards into TV receivers for compatibility with all regions. Currently the main standards are:

1) 720r. Resolution 1280x720 pixels, progressive scanning, frame rate can be 50 or 60 Hz, frame format 16:9.
2) 1080i. Resolution 1920x1080 pixels, interlaced scanning, frame format 16:9, frequency 50 or 60 half-frames per second, which corresponds to 25 or 30 frames.
3) 1080p. Resolution 1920x1080 pixels (2.07 MP), interline scan, frame format 16:9, frame rate 24, 25, 30, 50, 60 Hz.
4) 2160p. Resolution 3840x2160 pixels (8.8 MP).

Difference in standards

Striving to get the most quality signal on the TV when transmitting over a distance led to the appearance various standards tele-signal decomposition in different countries. The main characteristics of signal decomposition are the number of lines, frame rate and type of frame scanning.

The main television signal transmission standards are European PAL and SECAM, as well as American NTSC system. European systems use 625 lines, and American systems use 525 lines. These standards were invented at the beginning of the era of CRT televisions, and this fact must be taken into account. For example, the number of lines 625 is not fully used to form an image on a kinescope screen. Indeed, in the system of deflection coils it is necessary to provide time for the reverse movement of the beam, and therefore only 576 lines were actually used to form a visible frame. It is this number that is shown in the digital television screen resolution of 720x576.

The frame rate in old TVs was selected depending on the frequency of the current in the power supply network. For Europe 50 Hz, and for America 60 Hz. With this choice, it is easier to build TV scan generators.

All these restrictions on decomposition standards still exist today, because we have to implement compatibility between old and new TVs. But for digital devices (LCD and OLED) such restrictions are not necessary due to their design features. And the new high-definition television standard HDTV uses only digital transmission signal and it does not need to use lines for service pulses, therefore, the number of lines indicated in the name of the standard is the same that forms the picture on the screen. This signal decomposition standard contains 720 or 1080 lines, a frame rate of 50 or 60 Hz, and the scan type can be interlaced or progressive.

When designating a standard, a notation is used that indicates the number of lines of the signal, the type of scan is progressive (“p”) or interlaced (“i”), and the frame rate can be indicated through a slash. Progressive scan means that all the lines of the image are written to the screen at the same time, and interlaced scan means that the even lines are updated first and the odd lines are updated in another half-frame. Progressive scan is better and is what is mostly used today.

Throughout the development of television, the following types of television signal decomposition have been used:

LDTV – low definition television (240p, 288p);
SDTV - standard definition television (480i - NTSC, 576i - PAL);
EDTV – high definition television (480p, 576p, 720p);
HDTV – high definition television (1080i, 1080p);
4K UHDTV – ultra high definition television (2160p).
8K UHDTV – ultra high definition television (4320p).

The beginning of high definition television

Developments in the field of increasing the resolution of television pictures appeared with the introduction electronic methods signal processing. And this happened back in the 30s of the last century. Then they abandoned mechanical scanning, and it became possible to increase the number of lines on the screen. But on an industrial scale, the development of high-definition television (HDTV) began with the introduction of large-format cinema.

This happened in the 1950s, when television was developing at a rapid pace and, fearing competition, the film industry switched to wide-format films to protect itself, because they were more convenient to watch in the cinema. Such films were poorly displayed on simple kinescope television screens, and then television manufacturers began to develop high-definition television, which could perfectly transmit wide format to television screens.

But at that time, development stopped due to the need to use CRT screens with a large diagonal. The production of such displays for the mass consumer was not economically profitable. And only with the development of liquid crystal and plasma screen technology in 2000 did it become possible practical application developments in the field of high definition television (HDTV).

To implement HDTV, transmitters and receivers were developed, high-resolution screens were created, HD DVD and Blu-Ray media, HDMI and DVI-D data transfer interfaces were developed. According to the standard adopted in Russia, high-definition television includes 16:9 widescreen image signals with a resolution of 1920x1080. If the frame has a 4:3 ratio, then the resolution will be 1536x1152 pixels. This is how the HDTV standard came into being.

Good day! Many users understand permission as anything, so before starting to talk about it, I want to write a few words of introduction...

Screen resolution- roughly speaking, this is the number of image pixels per certain area. The more dots, the clearer and better image quality. So, each monitor has its own optimal resolution, in most cases, which needs to be set for a high-quality picture on the screen.

In this article I will consider the issue of changing the resolution, and typical problems and their decision in this action. So …

What resolution should I set?

This is perhaps one of the most popular questions when changing resolution. I’ll give you one piece of advice: when setting this parameter, I primarily focus on ease of use.

As a rule, this convenience is achieved by setting optimal resolution for a specific monitor (each has its own). Usually, the optimal resolution is indicated in the documentation for the monitor (I won’t dwell on this :)).

How to find out the optimal resolution?

2. Next, right-click on the desktop anywhere, and context menu select screen settings (screen resolution). Actually, in the screen settings, you will see the option to select a resolution, one of which will be marked as recommended (screenshot below).

You can also use various instructions for selecting the optimal resolution (and tables from them). Here, for example, is a clipping from one such instruction:

- for 15-inch: 1024x768;
- for 17-inch: 1280×768;
- for 21-inch: 1600x1200;
- for 24-inch: 1920x1200;
15.6-inch laptops: 1366x768.

Important! By the way, for older CRT monitors, it is important to choose not only the correct resolution, but also sweep frequency(roughly speaking, how many times the monitor blinks per second). This parameter is measured in Hz; most often monitors support modes of: 60, 75, 85, 100 Hz. To prevent your eyes from getting tired, set at least, no less than 85 Hz!

Changing the resolution

1) In video drivers (for example Nvidia, Ati Radeon, IntelHD)

One of the most simple ways To change the screen resolution (and in general, adjust the brightness, contrast, picture quality and other parameters) is to use the video driver settings. In principle, they are all configured in the same way (I will show a few examples below).

Intel HD

Extremely popular video cards, especially in lately. In almost half of budget laptops you can find a similar card.

After installing the drivers for it, simply click on the tray icon (next to the clock) to open the IntelHD settings (see screenshot below).

Actually, in this section you can set the required resolution (see screenshot below).

AMD ( Ati Radeon)

You can also use the tray icon (but not every driver version has it), or simply right-click anywhere on the desktop. Next, in the pop-up context menu, open the line “ Catalyst Control Center » (note: see photo below. By the way, the name of the setup center may vary slightly, depending on the software version).

Nvidia

1. First, right-click anywhere on the desktop.

2. In the pop-up context menu, select “ Panel Nvidia control "(screenshot below).

2) On Windows 8, 10

It happens that there is no video driver icon. This can happen for several reasons:

reinstalled Windows, and you got it installed universal driver(which is installed along with the OS). Those. there is no driver from the manufacturer...;
There are some versions of video drivers that do not automatically put the icon in the tray. In this case, you can find a link to the driver settings in the Windows Control Panel.

Well, to change the resolution, you can also use control panel. IN search bar Type “Screen” (without quotes) and select the coveted link (screen below).

3) On Windows 7

Right-click on the desktop and select " Screen resolution"(this item can also be found in the control panel).

Next you will see a menu that will display all possible modes available for your monitor. By the way, native resolution will be marked as recommended (as I already wrote, in most cases it provides the best picture).

For example, for a 19-inch screen the native resolution is 1280 x 1024 pixels, for a 20-inch: 1600 x 1200 pixels, for a 22-inch: 1680 x 1050 pixels.

Older CRT-based monitors allow you to set the resolution much higher than recommended for them. True, a very important quantity in them is frequency, measured in hertz. If it is below 85 Hz, your eyes begin to ripple, especially in light colors.

After changing the resolution, click "OK". You are given 10-15 seconds. time to confirm settings changes. If you do not confirm within this time, it will be restored to its previous value. This is done so that if your picture becomes distorted so that you cannot recognize anything, the computer will return to its working configuration.

4) On Windows XP

Almost no different from the settings in Windows 7. Right-click anywhere on the desktop and select “properties”.

Here you can select the screen resolution and color quality (16/32 bits).

By the way, the quality of color reproduction is typical for old CRT-based monitors. In modern ones the default is 16 bits. In general, this parameter is responsible for the number of colors displayed on the monitor screen. Only a person is practically unable to distinguish the difference between 32-bit color and 16-bit (perhaps experienced editors or gamers who work a lot and often with graphics). Whether it’s the butterfly’s business...

Thank you in advance for any additions to the topic of the article. I have everything for this, the topic is fully covered (I think :)). Good luck!
