Everything is changing rapidly in the modern world. Cameras of all models, from the cheapest "soap boxes" to professional "DSLRs", can shoot HD quality videos. This video is also possible for expensive mobile phones. DVD video standards are a thing of the past.
Film studios shoot new spectacular films with previously unavailable effects. The requirements for the standards of video and television equipment are also growing. Viewers want movies shot in better quality - 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 picture. This is the quality of pictures and text messages. Resolution unit - responsible for the formation of the image on the screen. Today, when purchasing a TV with a plasma or liquid crystal screen, you will surely come across the term Full HD - 1920x1080, which the seller will surely tell you about.
These TVs are now in every major store, they are affordable, and this is what buyers are looking for right now. If you answer that you do not know the term, the seller will add that this mark is the best recommendation for a TV, and the resolution of 1920x1080 is an indicator of high image quality.
How to choose a TV
When you make your choice of TV, then pay attention to measured in inches. One inch is about two and a half centimeters. But large-screen monitors are demanding on the video card. That is, if you bought a modern twenty-four-inch monitor from you, then expect your iron horse to slow down slightly.
Budget monitors 18-19 inches are good only for their price. And for those who love battle scenes on the big screen, monitors with 27 inches diagonally are suitable.
Some people are now wondering why modern monitors are so narrow and elongated. There is an explanation for this. For modern films, there are shooting format standards. They are filmed like that, with an elongated and narrow image. If you watch a new movie or play a modern game on an old square 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, other inscriptions are often found - HD Ready.
What's the difference?
The European Association for Telecommunication Technologies and Information Systems in 2005 adopted standards for new TV models that will display high quality video. They fell 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, can handle video with 1080 lines.
This name was taken up by the Japanese company Sony, when in 2007 it named a number of its products under the FullHD brand. Other companies in this market segment also began to call their products.
Therefore, most of the FullHD LCD and plasma TV receivers currently on sale (translated from English as "full screen resolution 1920x1080") have a 16 by 9 aspect ratio and support videos with 1080 lines of images. they are clearer and better quality.
So what is the screen resolution, how do the screen settings affect the picture that we see on the monitor?
A TV screen, whether it is plasma or liquid crystal, is a matrix that consists of pixels located horizontally and vertically on the screen. Their number is called the matrix resolution. There are many types of screen resolutions, but the most famous 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 come to a common standard around 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 can also differ in frame rate: fifty or sixty hertz.
In every modern TV there is a processor that converts the incoming signals to the standard that corresponds to the matrix of the TV. If the incoming signal and the matrix were with the same standard pixel resolution, then the image would immediately turn out to be clear and of high quality. But, since the 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 interlaced scanning
The range in which the TV channels broadcast is small. There is not enough room for everyone. The image transmitted by the channel can be formed in two ways. Progressive, which displays all frames in full (where the lines - even and odd - follow one after the other), and interlaced.
To save space on the air, a sweep was invented, which halved the frame rate. It was called interlaced. First, the first half of the frame is transmitted in odd lines, then the second half is transmitted in even lines. Interlaced scanning would look blurry if an action was not invented to return image quality.
In order to explain the method that forms the image, after the number of lines, they write the initial English: "p" or "i". For example: 1920 x 1080p resolution indicates that the picture was formed in a progressive way. And the 720i marking will mean that there are 720 lines in the video. And the letter i stands for interlaced method - interlaced. In order to indicate the format, indicate the frame size per second. When they write 1080p30, this means that this video has thirty frames running per second. The higher the number of frames, the better and more detailed the picture looks.
Full HD requirements
The latest generations of televisions display both types of scanned images. Thus, a screen resolution of 1920 × 1080 and a 16: 9 aspect ratio should be present on a 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, which includes twenty five HD-quality channels. Someday such channels will probably be free for everyone.
If you have problems with your monitor, fonts, or images, you need to understand that this changes due to the magnitude of the resolution. For example, when a high resolution value is set, let's say 1920x1080, then the objects will be clear. And more of them will fit on the monitor. And at 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 of 1920x1080 you like. 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.
A large monitor corresponds to the same high resolution. It sharpens and reduces the size of the image.
How to adjust monitor resolution in Windows 7
To do this, you need to go to the "Start" menu, then go up to the "Control Panel", and then go to "Appearance" and "Personalization". Then - in "Resolution setting" of the monitor. Now open the list next to the "Resolution" label, use the slider to set the resolution you need, then click the "Apply screen settings" button.
Later models of monitors, on liquid crystals, work with their own resolution. It does not need to be configured - it is already recommended for this type. Such monitors are divided into two types: with and the ratio of 16: 9 and 16:10 and standard with a ratio of 4: 3. If you compare them, then the widescreen has a large width and horizontal resolution.
If you do not know the resolution of the monitor, then it will be recognized from the reference book, on the manufacturer's website or by EDID.
What is EDID
There is a data standard, which contains information about the monitor and its parameters, about where it was produced, its resolution, size, color quality characteristics, and so on.
If you can't find out by EDID, then how to make the screen resolution
What if, when connecting a large-screen TV receiver, the image does not fit and looks cut off at the edges? To solve the problem, you need to update the drivers for your computer's video card. After that, in the computer setup, specify your model as the base, or primary monitor. Then you need to make sure that the TV is connected to the computer with a digital connection, and also that there are no restrictions on it.
Install the Moninfo EDID software (available on the Internet). Then 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 cope with this problem, you need to turn off the Overscan option on the TV receiver.
If this is a computer, then after the required video card, right-click on the desktop. If you have a GeForce video card, then go to the NVIDIA program settings. If you have a Radeon video card, then go to the Catalyst Control Center program. Then adjust the parameters with the slider in the "desktop" settings to the required value.
How to adjust the resolution
First you need to disable EDID.
Then set the resolution to 1920x1080 in the display properties.
Reinstall the video card driver (remove the old driver).
If the previous steps did not help, try reinstalling the Windows system.
Hopefully, after this information, the questions about how to set the screen resolution to 1920x1080 will be easier to solve.
Most modern users have heard the term Full HD, but do you know what it means? This term reflects the resolution of TV or monitor screens, movies, smartphone cameras and other products. Moreover, it is today the most famous and widespread, despite the emergence of new and better ones. The name appeared 10 years ago - in 2007. The author was the company Sony, which introduced it to make it very easy for the user to distinguish HD Ready (1280x 720 pixels) from Full HD (1920x 1080 pixels). But let's talk about everything in order.
Story Full HD
Long gone are the days when you didn't even have to peer to see the pixels in the image. The standard definition television signal has been replaced by high definition television.
Resolution - reflects the size of the picture received on the screen, measured in pixels. The quality and detail of the image largely depends on the resolution. The higher it is, the better.
Initially, high definition was represented only by the HD (High Definition) standard, the definition of which was suitable for all resolutions, starting from 720x576 pixels. It replaced the even older SD-resolution, which is part of standard television, which appeared back in the 40s of the last century with the launch of television to the masses.
Over time, everyone agreed that HD by the standard is 1280x720 pixels. Then, in 2007, as a higher quality continuation of HD resolution, Full HD appeared, which had 1920 x 1080 pixels, which significantly affected the quality. Like its predecessor, Full HD is used in high definition television. If in HD the image consists of 921,600 pixels, then in Full HD this number has grown several times - 2,073,600 pixels. The increase has a positive effect on detail, so that the viewer can see all the details of the image.
In addition, there is another version of Full HD, which is usually called amorphous. It is represented by non-square pixels and has a resolution of 1440 x 1080 pixels. It is also called HDV. Resolution appeared quite a long time ago, in 2003, so it is found in many video equipment. By the way, the first high-definition films released on HD DVD and Blu-Ray were presented in HDV.
Comparison HD and Full HD
Full HD, in fact, is not a separate standard - it is just a marketing tag (logo) to attract buyers and separate different resolutions, adopted by Sony. The name was simply borrowed by other firms to make it easier for users to navigate. If we see the HD Readi logo - the resolution is 1280x720, Full HD - 1920x1080.
Since Full HD does not play the role of a standard, it can be called an improved version of HD with a large number of pixels. For the user's eye, the main difference between the resolutions is the picture quality. Due to the increase in the number of pixels of the matrix, the screen offers a clearer and more detailed picture than HD or SD. Therefore, a Full HD picture contains an order of magnitude more information than previous resolutions. According to many studies, the difference in information quality can be up to 4 times the size.
Full HD can play content or display pictures of other resolutions, be it SD or HD. Matrices seem to "hold out" the lower resolution to the desired one. But the HD-screen is not capable of displaying a picture in Full HD. No, you can open it, but in the appropriate resolution (HD).
An important feature of Full HD resolution is the use of two possible scan types.
- Interlaced scanning. A frame scan method during which a frame is split into two fields. Fields are composed from rows selected one after one. That is, the image is displayed in stages. It is denoted by the letter “i” (for example, 1080i is a raster scanned resolution). This method is most popular in SD and HD matrices.
- Progressive scan. The method of progressive scanning, in which the frame is formed immediately on the screen. It is indicated by the letter “p” (for example, 1080p is a Full HD progressive signal). This scanning method is devoid of a number of disadvantages that interlaced screens suffer from. The borders of fast-moving objects are drawn an order of magnitude better - the comb effect disappears. There is no jitter in a frame that uses thin horizontal lines.
If we talk about technology with these resolutions, then, of course, Full HD is more popular. Although HD is still clearly not going to leave the market. There are still quite a few companies that regularly introduce inexpensive HDTVs. And a huge number of low-end smartphones still adhere to this resolution. As for popular TV set-top boxes, the overwhelming majority of models are available with Full HD, or even 4K support, which, of course, does not prevent you from connecting such a device to an old HD TV or even SD, the main thing is to find the necessary cables.
4K steps on your heels
Five years after the appearance of Full HD, in 2012, manufacturers began to present the first technology with support for 4K UHD, which provided higher details and a resolution that was almost four times higher - 3840 × 2160 pixels. Until recently, Full HD was nothing to worry about in terms of popularity, given the cost of the equipment that gave access to ultra-high definition television (). However, it has recently begun to actively conquer a significant market share. This was influenced by the fall in the price of 4K equipment, and the appearance of content in this resolution.
4K with new technologies really surpasses Full HD on many fronts, offering a deeper and more detailed picture, new playback formats. We can say with confidence that the new resolution will eventually succeed in ousting its predecessor, but this will not happen today or tomorrow. Just look at CRT TVs, which, despite the emergence of more modern models with high resolution and large displays, are still not gone.
A logical question arises: is it worth it to overpay a little for 4K Ultra HD or give preference to the proven Full HD? It is difficult to answer unequivocally, but if you do not buy a TV for a year or two, then you should consider 4K, which is only gaining momentum. If you doubt the need for the advertised 4K, and the budget allows you to change equipment quite often, then you can still look at an excellent model with Full HD. However, when choosing a TV, there are a number of factors to consider, and not just chase high definitions.
Full HD TVs and Set-Top Boxes
photo: Xiaomi Mi TV 3S The selection of Full HD TVs is so great that it will not be difficult to get confused. The emerging solutions with 4K, forced manufacturers to significantly reduce the prices of TV models with previous resolutions. Therefore, for relatively little money, you can pick up a high-quality TV, which will still delight you with a high-quality picture. For example, small options up to 22 inches can be bought up to 10,000 rubles. Up to 20,000 rubles, you can easily find a lot of good models with 40-42 inches diagonals. And in the region of 30,000-40,000 rubles, you can even pick up 50-inch solutions.
Running Android, although today they receive 4K support, they are in the best demand among owners of Full HD TVs that do not have a built-in Smart TV. Such devices play the role of media players, displaying content on the TV screen in the highest possible quality. Often, customers even refuse expensive TVs with Smart TVs, buying a separate set-top box, which is much more profitable. On average, TV Boxing with Full HD support will cost 1500-2000 rubles. If you plan to purchase a 4K TV in the future, then you can take a closer look at set-top boxes with the appropriate resolution. They cost a little more, but after that you don't have to buy a TV Box again to watch content in high definition.
Outcome
Full HD, no matter how quickly the technology develops, is still a high-quality and relevant resolution. Manufacturers do not forget about it either, regularly marking themselves with new TV models. If you do not pursue the highest quality and additional "chips", then you will still need a device in this format.
Buying a TV, everyone strives for the best and most successful model, which would have many interesting functions and high-quality images. The high cost of such a technique is not at all a guarantee of displaying a realistic picture. An expensive TV with built-in innovative technologies sometimes gives a blurry image. This effect can cause a difference in the resolution of the matrix and the format of the incoming video. So what should be the TV screen resolution for a high-contrast picture?
A TV that supports high resolution Full HD 1920px * 1080 can produce a blurry image if the input signal is 720 * 480 pixels analog TV, which comes from a conventional antenna. Therefore, when choosing a technique, it is necessary first of all to build on playable video files... The picture is perfect when the screen resolution and video signals are matched and presented in high quality. Perhaps worth it for better picture quality.
Manufacturers are pleasantly pleased with the variety of models using various technologies that distinguish one option from another. At the same time, eyes run up from the multitude of additional functions and the introduction of innovative systems, and it is very difficult to decide which parameters of the TV display are better.
Screen resolution and video signal
TV components
Along with the number of pixels located in the horizontal and vertical planes, the type of scan affects the image in projection and panel screens. She may be:
- interlaced and designated "i";
- progressive, denoted as "p".
In the first case, the picture is updated in 2 stages every 30 seconds, first even, then odd. This effect in a lighted room, with an increased degree of ultraviolet rays, can cause flicker... Progressive is better: it has a positive effect on image quality as it updates all lines at the same time every minute.
The playback quality also depends on signal decomposition and is divided into the following types: SDTV, EDTV, HDTV and stands for standard definition of a signal, enhanced and high, respectively. These indicators are grouped and determine the type of resolution.
TV resolution depending on its technology
Different types of TVs have their own standards for good picture quality. Progress does not stand still, and manufacturers are introducing new technologies that allow the virtual world to be transformed into reality. To determine which TV resolution is best, consider its types and technologies that provide picture quality.
Almost all 4K TVs support HDR - High Dynamic Range, which brings the picture as close as possible to reality. But the authenticity of colors and shadows is transmitted only through videos on 4K Blue-Ray discs and Netflix video files.
New technologies ensure the transfer of colors in natural colors and reproduce very clear contours. Modern televisions are equipped with high definition screens. But not in all cases this can have a positive effect on the playback quality - the high fidelity of the display dictates a certain format of the incoming video file.
How to choose the best resolution TV
Optionally, a lot of pixels will allow you to get the perfect image. Taking into account the signal source, you can choose the best option to achieve the best effect. An HD-Ready screen is enough to play cable TV and terrestrial TV signals with a built-in digital DVB tuner. Such a TV will allow you to reproduce high quality HD video and read DVD-format video files. For Blue-Ray connectivity, satellite TV viewing and usability, it is better suited Full HD screen.
Recently, TV manufacturers have been increasingly luring buyers with the high resolution characteristics of their products, thereby leaving many with rather difficult choices. On the one hand, it is somehow inconvenient to lag behind progress. On the other hand, after all, we still most often use TV to watch ordinary TV channels and DVD movies. And then there was a popular rumor that high resolution harms the quality of reception from a conventional antenna. Let's try to figure it out.
There are three main analog color television standards in the world - NTSC, PAL and SECAM. The NTSC system is common in the United States and Japan, among others. PAL is used in Western Europe (excluding France) and some other regions. SECAM is adopted, in particular, in France, the countries of Eastern Europe, in Russia and on the territory of the former USSR. It should be noted that the PAL and SECAM systems are based on similar principles, therefore, in modern TVs, SECAM support also implies the presence of PAL support. Now SECAM is used almost exclusively for television broadcasting, even in our country DVDs are recorded in the PAL system.
The TV signal is divided into lines. In the NTSC system, 525 lines are transmitted, in PAL and SECAM - 625. However, some of the lines are used to transmit service information, therefore, 480 lines are visible in NTSC, and 576 lines in PAL and SECAM. The image resolution is 640x480 pixels for NTSC, and 720x576 pixels for PAL and SECAM. In this resolution, video is recorded on DVD in both 4: 3 and 16: 9 aspect ratios. In the latter case, the picture is "compressed" in width during recording and then "stretched" during playback.
Matrix resolution
If we look at the resolution indicators of modern day, we will find that they do not coincide with the European standards for television broadcasting. The most common resolutions are 640x480 (LCD TVs with an aspect ratio of 4: 3); 852x480 (plasma panels with an aspect ratio of 16: 9), 1024x768 (LCD and "plasma" both 4: 3 and 16: 9); 1366x768 (HD Ready); 1920x1080 (Full HD) pixels. There are, but rarely, some other resolution values, for example 800x600 or 1024x1024 pixels.
Converting the resolution of the original signal into the resolution of the TV matrix is carried out by a high-performance processor built into the TV, which costs a lot of money. What is the reason for such a wasteful decision? There are at least two reasons for ignoring European television standards. First, until recently, the USA and Japan were the main consumers of LCD and "plasma". Accordingly, the resolutions 640x480 and 852x480 take into account the peculiarities of the NTSC standard. It is extremely unprofitable to produce different dies for the USA and Europe - setting up the production of each type of matrix is very expensive. When the demand for liquid crystal and plasma panels increased in the European market, it was already time for the transition to high definition television. So the manufacturers just mastered the production of matrices for HD Ready and Full HD. The only exception was Sharp, which will be discussed below. But her idea of an LCD TV with a "European" matrix did not develop in the end.
The second reason is the desire of manufacturers to add new features to their products, providing themselves with a competitive advantage in the market. A resolution of 1024x768 pixels is optimal for most computer applications. Therefore, a TV with a resolution of 1024x768 or 1366x768 pixels can be used as a computer monitor without any problems.
In this regard, it is worth mentioning separately the relationship between "computer" resolution and HD Ready. HD Ready means the ability to reproduce a picture with a resolution of 1280x720 pixels. When using a matrix of 1024x768 pixels, the resolution will be less than that of the original signal. For compatibility with a computer, 768 lines are made in the matrix, that is, a little more than is required for HD Ready, and to comply with the 16: 9 aspect ratio, there will be 1366 pixels in each line.
As for the attempt to create an LCD TV with a "European" matrix, it was undertaken by Sharp several years ago. Moreover, a new production line was not created for this. It's just that the LCD matrix was sawed into four parts, each of which was slightly cut in width. The result is LCD matrices with a resolution of 720x540 pixels. Why 540 and not 576 pixels? Yes, because it is half of 1080. As a result, the picture was cropped a little from the top and bottom, but for the user it was almost imperceptible. However, for reasons unknown to the general public, Sharp is no longer creating new models of LCD TVs with a "European" matrix.
Image conversion
The highest picture quality is achieved when displayed on a pixel-to-pixel basis. In this case, the resolution of the input signal exactly matches the resolution of the TV matrix.
But one must understand that for the television broadcasting system adopted in our country, displaying "pixel-to-pixel" on a modern LCD TV or "plasma" is impossible. Neither is it possible for DVDs recorded in the PAL system. There will be a resolution conversion anyway. The pixel-to-pixel display is only available when you insert an original American disc recorded in NTSC into your DVD player and watch it on your TV at 640x480 pixels. In this case, the aspect ratio of the frame in the film will be 4: 3. In fact, some connoisseurs of high image quality follow this path. Only they use a plasma panel with a resolution of 852x480 pixels and an aspect ratio of 16: 9. The widescreen picture is stretched horizontally, but the number of lines remains the same. Indeed, if you are watching an American DVD, then subjectively the picture on such a panel may look better than at a higher resolution. Although the American NTSC system is actually worse than our SECAM, not to mention the Western European PAL.
Conversion of resolution with a minimum of distortion is much easier if the number of lines is changed by an integer number of times or with a fractional factor when there are relatively small numbers in the numerator and denominator of the fraction. The ratio between 576 SECAM lines and 480 lines displayed by an LCD TV is 4/5. Quite an acceptable value for the processor. And what if the TV matrix displays 768 lines? Then the processor must increase the number of rows by 4/3 times. That is, where there were 3 lines, you need to "draw" 4 lines. Quite a feasible task.
If a TV broadcast is broadcast with a 4: 3 aspect ratio, and you want to "stretch" the picture to fill the screen with a 16: 9 aspect ratio with minimal distortion. Then the following technique is used. The image is slightly "compressed" vertically so that the change in aspect ratio is not yet striking. The top of the image is cropped to create a 16: 9 picture. At the same time, subtitles are preserved, which, as a rule, go below. This mode is called something like "Subtitle Enlargement" in the TV menu. This image transformation is much more complex than increasing or decreasing the number of lines, but also within the scope of the processors installed in modern televisions.
However, when choosing a TV to receive over-the-air transmissions from a conventional antenna, buyers often try to take a model with a lower resolution, since it is supposedly more resistant to interference. But in reality, noise immunity does not directly depend on the resolution. Everything is determined by the performance of the processor and the quality of the built-in tuner. Problems can arise only if the processor performance is insufficient for a given matrix resolution.
Sharp is perhaps the only leading LCD TV manufacturer currently creating new 640x480 pixel models. In other cases, it will be either an outdated model or a secondary manufacturer, which may have saved on the quality of the tuner. So the desire to buy a TV with a lower resolution for the sake of the possibility of high-quality reception from the air is completely unjustified.
One of the reasons for the low noise immunity of the TV can be all kinds of signal processing functions aimed at improving the display of movies recorded on DVD. Interference on the air can "confuse" the TV and these functions, on the contrary, will reduce the picture quality. Therefore, when choosing a TV for receiving terrestrial channels, it is better to give preference to a model where there will be less of all kinds of improving signal processing, or they will be disabled.
And finally, about the choice between 1366x768 and 1920x1020 pixels for TVs larger than 45 inches diagonally. Yes, if you are not going to switch from DVD to Blu-ray any time soon, Full HD resolution will be overkill for you. However, a subjective comparison of Full HD and HD Ready TVs shows a better picture from the former, even when playing DVD. The secret is revealed simply - Full HD matrices, both for LCD and for "plasma" are produced using more modern technology. Even if HD Ready TVs have almost invisible pixel structure, Full HD TVs often outperform them in terms of brightness, contrast and color accuracy. Another issue is that Full HD TVs cost significantly more than HD Ready TVs. And it is precisely this circumstance that so far largely determines the choice.
Is Kumu profitable? I'm not a big believer in conspiracy theories. And even here it just happened, without anyone's help, but it was quickly picked up by manufacturers and sellers of computer equipment. By converging public opinion, we come to the conclusion that 1080p resolution is not enough for monitors with a diagonal of 27 inches. There are a lot of comments and reviews in this regard, and most of the people who left them adhere to the position of insufficient 1080p resolution. But is it really so?
In front of me are two 27-inch monitors (no matter which manufacturer, with a TFT AH-IPS matrix), one with a FullHD 1920x1080p resolution, the other 2560x1440p. I worked with them for about two weeks and I formed a clear opinion, different from what I have seen in hundreds of comments.
I cannot identify any particular consumer benefits of the latter. We can say that at a resolution of 2560x1440, 1.8 more information fits on the screen than at FullHD. But this is nonsense, with relatives dissatisfied with the audio signal delay as much as ~ 0.002 seconds in wireless headphones. I also had to work in engineering CAD programs, where there can be a lot of information, while there is practically no difference in convenience between the two monitors. Rather, it is there, but so imperceptible that it can be considered its absence.
Windows 7 (and 8, respectively) has support for different DPI values, which will allow you to set the correct scales in your workspace. Most often, problems arise precisely with a higher DPI, clipped text, incorrect font sizes, window size problems, pixelation (which has become a headache for webmasters, especially with the advent of retina displays) of bitmaps.
And when I launch a game, the 1440p version even loses out due to lower performance. At the same time, the picture does not get much better in games. More enjoyment from the game is acquired not because of the density of dots per inch, but because of the diagonal of the monitor. Below you can clearly see the dependence of the optimal diagonal on the resolution, taking into account the distance from you to the screen.
In summary, it is better to buy a monitor with a larger diagonal, rather than a higher resolution. At the same time, it turns out a pretty solid saving for your budget. 1080p is enough for a 27-inch monitor, but that's the limit. In the case of 1080p resolution, with large (over 27 inches) diagonals in games, you will not lose anything, but you can lose comfort in working applications or, for example, when surfing the Internet. If your choice fell on the 27-inch diagonal, feel free to take the cheaper option with 1080p. And if you are looking at monitors of 30 inches or more, then the choice should already fall on monitors with a higher resolution.
Those who say that 1080p is not enough for a 27-inch diagonal are cunning, because most did not use such monitors and advise only on the basis of a stable picture formed in the Internet space. This opinion is also supported by fans of Apple products, whose 2560 × 1600 resolution was shoved into a laptop with a 13-inch screen.
