Does it make sense to 4K TV. The advantages of televisions with the resolution of Ultra HD

Mysterious resolution 4K: We understand the advantages, disadvantages and prospects

One of the technologies in which the entire Internet is expired is a high resolution image. The notorious phrase "4K in 60 FPS" became nominative in PC-gamers, and any self-respecting video service tries to quickly declare support for 4k-video. Let's deal with what it is and whether it is necessary to think about the 4K ordinary user.

First terminology: 4K is either the display resolution, or the resolution of the video that you will lose on it. Generally accepted standard: 3840 at 2160 pixels, but:

There are many names and nuances

At the same time, in the course and other name of the technology, Ultra HD, and abbreviated - UHD. In the incatch it comes to him and another popular standard, Ultra HD Premium.

This marking means that the TV or monitor supports the playback of HDR content. HDR video wins the usual coverage dynamic rangethat Sulita simple user more bright and rich picture, without unnecessary lights.

Take care of color

In addition, the Ultra HD Premium device must support a 10-bit color depth - that is, up to a billion shades. Take into account: such a TV will not necessarily be able to play them all, but the signal will definitely process.

Normal television standard: 8-bit color. In it from the RGB color palette with about 16 million shades, any 256 is selected for the output of the picture. Two additional bits are already issued by 1024 shades.

The color sensitivity of our eye is much higher than the 8-bit standard, so the difference is noticeable to the naked eye: the picture looks rich. In addition, the DWORD with Ultra HD Premium will show you to 90% of the color space P3. On its use in recent iPhone, iPad and Mac. It covers more colors.

With the overall name 4K, everything is very simple - it roughly indicates the number of pixels along the horizontal display line. They, as we have already spoken, about four thousand - that is, four times the standard Full HD with its 1080 pixels. In a visual comparison, it looks much more impressive.

What does all this mean in reality?

If very brief - the picture is much clearer and pleasant. Especially well noticeable advantage of 4K on large and very large (for example, 65-inch) screens, so try to choose a TV or a monitor be more.

At the same time, many recommend planted to it. a little closer -even at a distance of a pair of steps, the clarity will not fall. The logic is extremely simple: the pixel density is higher, so you will not see the grains, and the larger viewing angle will have a positive viewer on watching experience.

How and what to watch

However, all charming 4K, by and large, truthful of television content. Indeed, Netflix and torrents have enough TV shows and films in ultra-high resolution.

But to play them it will be necessary to tinker. In the case of an Smart TV, there are options: from Application Store (Netflix, YouTube) or a prefix, like Roku 3 or Chromecast Ultra. Note that Apple TV 4th generation does not pull such permission.

There is also a conservative approach. You can buy a Blu-ray player, and then buy by discs to watch movies. But this is a very expensive option.

"Clear" and high resolution

Perhaps you will come to mind the idea of \u200b\u200bbuying a new PS4 Pro from Sony - after all, this company promoted the use of Blu-Ray with its prefixes. So, do not get fooled. Newest console Does not be played 4K with Blu-ray mediaBut perfectly cope with such a video in Streaming.

At the same time, the usual Blu Ray with permissions smaller drive will cling without problems. In addition, you can ship 4K movies on the USB flash drive or hDDBy connecting them to PS 4 Pro - especially since the transfer rate is supported up to 6 GB / s.

Subtotals

Total, you can watch 4K on a TV with a resolution of at least 3840 to 2160. If it is a Smart device, then content necessary permission You can find in applications like Netflix or YouTube.

They can also be used on smart consoles or consoles. In the case of Play Station, the Pro version will be required. You can 4K you can fight or connect from the media. You will precisely get the pleasure of viewing, but is it worth the game of the candle?

Imaginary 4k and why it is necessary

Moreover, it is with the game rank in 4k not so good. To begin with, I will achieve the question with consoles. Most affordable option For gemina in this resolution - all the same PS 4 Pro.

It costs about 30,000 rubles, but in most demanding games it does not produce present, or native, 4k-permission. This is associated with high chart requirements: drawing such a picture requires four times more resources than the usual Full-HD version.

Due to the lack of resources, the console render image in the format of "chessboard". Imagine that the black squares are "drawn" in the present 4K, and white only mimic it using extrapolation.

In full and "drunk" 4K will be sent not the most demanding games. By the way, a recent competitor from Microsoft, xbox consoles One x, power is enough for full support Such permission even in top toys. But here there remains a catch.

Hertz, FPS and optical deception

The 4K-resolution TVs and monitors have a limit on the speed of the screen update - only 60 Hz. Clarify what the difference between hertz and fpsnot to confuse them among themselves. So, the figure in Hertz is the maximum allowable value for changing the picture in a second. The 4k monitor will be able to change 60 frames one second.

However, not every video card will have time for such a tempo. In FPS games, that is, the number of frames per second, it is a dynamic indicator. But critically important - it increases the smooth picture and helps to avoid unpleasant jerks.

Many gamers choose monitors with more modest permissions, but 120-gentle. Even if the game continues to be displayed in 60 FPS, then each frame will be updated 2 times in 1/60 seconds. For human Eyes. It looks like optical cheating: it seems that all a little smaller. The same story with the films. Let them remove on the filter 24 FPS when viewing "at high frequencies" you will not see the effect of accelerated rewind.

What is the result?

Due to the technical difficulties of the 4K TV or the monitor has a modest update frequency - 60 Hz. In the games it may not be enough. For films will be for the eyes. Now we collect the rest of the moments in a bunch.

It is best to take a device with 10-bit and HDR support. It will provide the most good picture. In the case of TVs, it is worth noticeing to a large diagonal - it is precisely on such a scale that will be justified. But the device itself is not limited.

For full effect You need and the content shown in the appropriate resolution. You can watch it on Netflix, YouTube and a number of other services. They are published in 4k and films, but do not expect the same abundance as with more modest permits.

Do I need to take right now?

4k - leading technology for the coming years, which soon will be standard For the entertainment industry. But it is not worth a hurry to run to the nearest stores of technology.

Look at the 4K TV (showing the picture in the resolution four times higher than HD) is like opening. On the video with the city scenery shown at the beginning of the month at the Samsung press conference, one could see individual windows in most buildings, as well as individuals belonging to the skyscrapers and leaving them. At consisting of eight million pixels, it is very difficult to notice the mesh structure (unless, of course, you do not look from a very close distance), and the image itself looks like a clear photo, but only in motion.
Nevertheless, the world that can be seen on the screens of 4K-TVs is, to a large extent, just an illusion - perhaps created from several clips filmed by High End class filmmers.
The price is a key factor holding us from the immediate purchase of a 4K-TV (which is so called due to the fact that its screen diagonal is about 4,000 pixels). Usually, such a TV costs at least twice as much as a HD TV (the same size, with a high-quality panel, the possibility of accessing the Internet and the same set of functions). However, even if you imagine that the money does not play for you, or that prices suddenly have fallen unexpectedly (and this is not fiction - small companies are already selling models at lower prices), there are still four reasons to make you postpone the purchase of 4K -Televator.

Lack of 4K-content

Today, there are no blu-ray discs on the market, platforms with streaming video, television channels and even more or less convenient to use camcorders that would support resolution in 3840x2160 pixels. And this is the first reason in order to pay the purchase of a 4K TV and wait a bit. Moreover, waiting can be long enough.
Currently, companies producing TV equipment are trying to provide some kind of limited number of 4k-video on the players containing hard drives. Sony, for example, offers 4K / ULTRAHD Media Player.On the hard disk of which 10 films are recorded in 4k-format. The device is sold at a price of 700 dollars. Sony also promises before the end of the year to provide an opportunity to download the player from the network up to 100 films additionally (you can only dream about the stream viewing - the file sizes are very impressive). However, 700 dollars - too much money to spend them on buying a device that can show only a small set of films.
A similar media player with a hard disk inside plans to present in the near future and Samsung.

Few additional advantages
For conventional HD content

Currently, 4K-TVs can scale any HD video up to 4K by "constructing" an image with additional pixels based on assumptions relative to their content (just as it happens when you are viewing on the HD screen. Normal old DVD with video standard permissions) . The results look quite acceptable on the screens of some TV models, in particular, such as Aquos Ultra HD LED TV production of Sharp with a diagonal of 69.5 inches (1.8 meters). This model He has a certificate from the THX laboratory confirming the quality of scaling, and costs $ 8,000. However, if you move closer to the screen (as far as pixels allow you), you will notice the grain structure of the scaled video.
Even a scaled video on a 4K screen will allow you to comfortably sit to this screen at a closer distance than in the case of a HD TV, but not so closely so that you can talk about how about something worth it. The Chamber of Standards at the International Telecommunication Union recommends to look at the 4K screen from a distance of at least one and a half times higher than its height (so as not to see individual pixels), and in the case of HDTV, sit preferably at a distance that exceeds the screen height of at least three times.
Thus, if you have a 55-inch TV (1.4 meters) - start-up models from Sony and Samsung have such diagonals, you should sit at a distance of 1 meter from the screen, if it is a 4K TV, or about 2 meters from Screen, if it is a HD TV. And it became if you do not want to sit closer than 2 meters from the TV screen, you should not spend extra money. SAMSUNG.For example, only recently began selling models of 4K-TVs with a diagonal of 55 inches, and they are 5,600 dollars. At the same time, the most best model HD TV production of the same company with the same diagonal costs 2,800 dollars (in addition, in the line of models with a 55-inch screen from Samsung, there are cheaper.

4k-video can be intermittent

Unfortunately, you will not be able to see on your 4k screens in perfect quality even then a small amount of video in the 4K format, which is available today on the market. All because even the most latest models HDMI cables (version 1.4) are not capable of transmitting such a large amount of data without problems. A signal coming to most HD TVs from devices similar to Blu-Ray player is transmitted at 60 frames per second. However, when transmitting video to four times more resolution via an HDMI cable, the only output will be cut into a twice frame rate. But you see, at the speed of 30 frames per second, the video will not be so smooth.

4k-video may suffer from lack of flowers

Another compromise - in color details. Due to restrictions bandwidth The channel connection via HDMI 1.4 can transmit a 4k signal in which the color data is cut to 8 bits (256 shades) for each of the three pixel components (red, green and blue). Combinations of these primary colors give a spectrum of 16.7 million color shades. Perhaps, at first glance, it seems well, however, modern liquid crystal panels are able to display a 10 bite color palette (about a billion shades). Thus, the ultra-high resolution of the video will be adjacent to a relatively poor color palette.
However, engineers and scientists are already working on solving these problems. A new version hDMI interfacewhich will be called HDMI 2.0, will be able to transmit 4K video at 60 frames per second. However, improvements in the transmission of the color palette is most likely not foreseen until the next standard of interface standard updates.

Here are some basic facts about the new HDMI 2.0 standard:

• Resolution [Email Protected]/ 60, (2160p), which is 4 times higher than the quality of the picture resolution 1080p / 60.
• Up to 32 audio channels will help achieve the effect of complete immersion in the multi-faceted sound gamut.
• Audio sampling frequency up to 1536 kHz will help achieve the highest purity of sound.
• The ability to simultaneously transmit double stream video for multiplayer screen.
• Simultaneous transmission of multi-threaded audio for multiple users (up to four).
• Support for wide-angle theater video with the aspect ratio of 21: 9.
  Dynamic synchronization of video and audio streams.
• Extended CEC bus offers broader control and control capabilities from one point various devices consumer electronics.

The prospect of the new HDMI interface standard is a warning for those who buy televisions and other electronics containing the standard type HDMI ports. Although some companies will be ready to conduct an upgrade of the ports of the ports produced today. For example, in all 4K-TVs manufactured by Samsung there is an external unit that contains the ports of the video signal input and produces some processing of this signal. In the event of new standards input interfaces, the user will have only to purchase a new block.
However, this is not such a good way to make the consumer pay at least twice as much for the TV for which today there is not so many native content, which shows this content with some "jagging" and disadvantage of flowers so that with time, with the advent of new advanced technologies, Again to pay - already for the upgrade of your model. Moreover, by the time the 4K-TVs available in the market will be much cheaper anyway.

Wearing the sphere of electronics, users noted the appearance of the opportunity to buy a huge TV with which the image is shown in highest quality on thin i. big Screen. Innovative technique allows each user to enjoy high-quality video, with a detailed picture. With the popularization of upgraded instruments, consumers think that better - or Full HD? What option is more expedient?

The advantages of televisions with the resolution of Ultra HD

The first dignity of Ultra HD is a convenient view of the TV at a relatively small distance. The screen of such a device is known for resolution, which is considered ultrahigh (approximately 8 million pixels).

This means that the picture is maximally detailed and it looks more clearly, compared with previous modifications of TVs. The main advantages of Ultra HD should include:

• Clear image detail, through the use of branded technologies and increasing the pixel density. A person easily perceives such a picture.
• The frequency indicators of the progressive sweep - up to 120 frames per second. As a result, the load on sight is reduced, and the eyes are not so tired, even if watching TV for hours.
• Deep display of a large number of colors.
• Increase dynamic range. In the most clarified and darkened areas of the picture, any detail is transmitted very clearly. All shades and colors seem brighter and rich.
• Increased sound quality. In Ultra HD TVs, for example, in the model, a multichannel sound is realized, with 24 audio channels.

Such an technique will attract the attention of video game lovers, because it creates the most realistic picture, contributing to an alleged immersion in the world virtual reality. In stores you can already find games with support for this format.

4K Matrix creates a three-dimensional image viewed by the viewer from all positions. To view a high-quality three-dimensional picture, 3D glasses are not needed.

The main disadvantage of such equipment is the lack of sufficient content. Despite the appearance of 4k TVs, files that support such a format, while negligible. To view TV channels on such a device, complete equipment update is necessary. Now they are not able to transmit a signal in the desired format.

Watch Channels tV Ultra. HD in a smaller format can be, but it will negatively affect the image - contrast and clarity will suffer, the picture will begin to "stretch".

Is it enough content in high resolution, and where to look for it?

Despite the popularization of such equipment available to a wide range of content to view high resolution while little. You will not be able to see your favorite movie or serial in 4k format. We have to spend time looking for suitable files.

Some online services are already provided by such content. For his search you can use:

• YouTube. It broads programs and films in the UHD resolution since 2014. Rollers are designed for free viewing - It is enough to put the amount of resolution 2160 and enjoy the high-quality image.
• Netflix. This service became available in our country relatively recently. In his video current a lot of files in high resolution, but to view them you need to pay a subscription. There is a free period for familiarization.
• . This resource uses a section with free content Very high definition. LG TV owners can be viewed and with WebOS 3.0 OS.

In 2016, several Blu Ray disks with increased resolution appeared. Such content also provides services IVI, OKKO.

So choose: Ultra HD or Full HD?

The answer to this question is ambiguous. Innovative technique gradually conquers positions in the modern market, but there are few wishing to use it. This is due to the great value of Ultra-HD TVs. This can be verified by the example of the model. Even if a person is ready to buy an expensive device until he can fully use it, due to limited content.

Unfortunately, the realities of our life and the electronics market in the country are not yet adapted to use innovative devices and viewing files in ultra-high resolution. Therefore, the question is which TV to buy - or 4k, logical.

Purchase 4K TV is associated with a number of difficulties. To fully use it, you will need high-speed Internet and specialized HDMI electrocabel. The owner of a modern TV device will have to spend time looking for and buying suitable content. Satellite channels intended for viewing in such a format, there is almost no in our country.

At the same time, if you are ready for fundamental changes, you want to get acquainted with the latest technologies, and detailed, a clear image for you above the other - it is worth a risk and purchase a Ultra-HD TV. As an example, it is worth considering the model LED 3D 4K LG55 55UC97OV.

Innovative technique in our time is designed for people who do not have fear of innovations and are ready for bold experiments. But if the functionality of the TV is important for you, with such an expensive purchase it is worth having time.

Making a choice in favor of modernized technologies, you may not doubt - over time they will not be obsolete, but will become even more popular. It will take several years, and this technique will become much cheaper and more convenient to use. The world is already trying to adjust the format of 4k - it is rapidly developing, so we have a reason to argue that he will soon finally displacing other TVs from the market.

Introduced in the electronics market in 2012 4K TVs do not quiet to buyers. Samsung, LG, Sony, Philips regularly present panels that support Ultra HD format. You can see and choose the latest new items at http://www.citrus.ua/shop/goods/tv/1578/. Should I buy a 4K TV in 2018? Or wait a couple of years? Or not buy at all? We will answer all the exciting questions about 4K TVs.

4K TV is a TV with a highly detailed image with high color reproduction, brightness and contrast parameters. Such a screen has a resolution of 3840x2160 pixels. This is four times higher than the standard Full HD, the resolution of which is 1080 points.

4K TV creates a really impressive picture: clear, bright, contrast, with rich color reproduction. Especially spectacular to watch the video on the panels with a diagonal of 50 inches and more.
High pixel density allows you to watch videos at a distance even pairs of steps. In this case, the quality of the image does not deteriorate. Manufacturers of new 4k monitors assure that the eyes are less tired when viewing the video in such a format, since the frame update frequency is higher than in the formats used now.
