For ordinary consumers, "4 k" and the "high qing" is no different, they can be replaced. However, when you and a video and film production industry experts, he would say we these consumers "have no culture" mouth "4 k" is not really "4 k", don't be angry, and he is not laughed at, technically, he was right.
Use terminology to explain, 4 k is a resolution of 4096 x 2160 pixels digital cinema standard, 4096 is a horizontal measurement, and 2160 is vertical measurement, they are through suitable for 1.9: the proportion of 1 and calculate. In digital, described in 4 k it makes sense, because it is 2 k (2048 x 1080 pixels) twice.
Back to the consumer market, after all, most of us still at this level, we watch TV basic is 16:9 and 1.78:1, the proportion of this as professionals to use wide screen size, so we get the final resolution of 3840 x 2160 pixels, it actually is 1920 x 1080 standard (that is, most of us now often say or full hd 1080 p) twice, that is why we always hear high-definition TV makers said 4 k resolution is four times as much as 1080 p.

In 2013, the consumer electronics association (ComsumerElectronicsAssociation, CEA) decided to end all the confusion between the two, also in order to make the marketing more easy, ultra-high resolution (UltraHD) is the official name of the new resolution standard. People call "4 k", however, time is too long, suddenly want to switch to the "high qing" seem to feel uncomfortable, so manufacturers such as SONY still called high-definition TV 4 k TV, thus, renamed problem cannot be solved more.

Do you need super clear?
We naturally ask, whether I need such a "fine visual delicacies"? No, don't need to, of course, mid-range also is quite good, isn't it? Further said that a few years, 1080 p high-definition television can still work, because 1080 p broadcast standards will not easily like 2009 analog broadcast standard "decline". , of course, can't guarantee you sitting in front of a 4 k high-definition TV when viewing images withstand the temptation to describe a buy.
The advantage of high-definition television
There is no doubt that the most intuitive advantages must be higher resolution, in the same space, high-definition screens filled with 8 million pixels, and the 1080 p television is only 2 million pixels. This is one of the most obvious upgrade, especially in the user to watch the original 4 k when the media file effect is more obvious, the inside of the pixel is 4 times that of 1080 p television is small, each small piece of picture of pixels to add 4 times, image clear and bright. To a certain extent, this is why high-definition TV using the cause of the larger screen size will be more meaningful, because these extra pixels in the large screen will have a greater impact force.
More pixels in the screen, however, does not mean that in the larger TV has a better picture quality, because when the user to sit away from TV special close, very difficult to see each pixel. So nest in far from television some sofa or bed will be more comfortable, you can notice the high-definition TV can provide a wider color gamut, image depth is also higher.
Some experts question when viewed from the typical viewing distance 55 inches below the high-definition picture screen, foreign media at first agree with the statement, that for most people, a small screen size of high-definition television seems to be the effect not beautiful. But then they will be a 1080 p TV and high-definition TV in contrast, the former 1080 p blu-ray video, which play the same video of high-definition version, typical viewing distance from the TV screen, play the effect of the difference is obvious.
HDMI can deal with 4 k video?

Yes, it is ok, but if you want to make full use of some features of the ultra clear, it must be the correct version At present most of us use the HDMI standard is HDMI1.4, the cable criteria can be up to 30 frames per second of ultra high resolution content. However, if you want to make better use of the higher frame rate of ultra-high resolution, colour and a function of depth, HDMI2.0 will be needed. And in the end, after HDMI2.0 also need HDCP2.2 copyright protection (hd). But you also need not worry, because they don't need to buy a new cable, can also be used for now.

High-definition TV shows or hd content will become a standard?
Foreign media that will be, but not all TV. If a high-definition TV to play sd or hd resolution content, the content of the first need to be upgraded. Most blu-ray players are built into the upgrade chip, the contents of a DVD (480 p), can be converted into 1080 p content, so it looks more comfortable in 1080 p on TV. Similarly, high-definition TV also need will be displayed before the sd or hd content into ultra-high resolution, after all the extra pixels need to be filled, isn't it? But need to note that while most of the big brand TV manufacturers of high-definition television can complete resolution upgrade work, some cheap brand can't. But in the near future this situation should be changed, because the upgrade chip will become more and more common, will be cheaper.
At present, the native high-definition 4 k content of scarce phenomenon led to the escalation of the TV ability become a key factor. Believe in the near future, users on high-definition television see most of the content will be 1080 PhD, 1080 I or 1080 p. If the resolution of the TV upgrade ability is too weak, that all will see too much less effective than real 4 k content.
What we can get the original 4 k resources?
If you have a SONY 4 k TV, and product package to get the company 4 k media player, you can get more than 200 4 k movie, otherwise there is no other choice. Samsung shipment is also a high-definition video package, in the form of equipped with USB hard drive, there are some high quality high-definition TV. However, there are many ultra hd content on Netflix, the future will also add more, let us wait they are deployed.
For 4 k content in play, only there are some channel can in Europe and South Korea, at the same time, the BBC in the UK are also plans to introduce 4 k video, in the United States will have 6 months to 4 k play test period, but only in certain designated areas. As is known to all, the 2014 World Cup in Brazil have 4 k broadcast channels, but only some of the satellite viewers in Japan enjoyed the high-definition pictures.
What is 8 k? 4 k will be eliminated?
8 k resolution of 7680 x 4320 pixels, or known as 4320 p, is 4 k resolution of 16 times as much as four times, 1080 p. Such a high resolution seems incredible, but it really exists, and the major manufacturers have been ready for this reason, believe in the near future will see some 8 k prototype products in the future.

This can not help people thinking 4 k time available, because it may only be stepping stone in 8 k, like 720 p soon replaced by 1080 p. Japan's national broadcaster, NHK, has begun to promote 8 k, and according to h. 265 compression technology is in the key step towards the right direction, BBC London Olympics in 2012 is part of the content to 8 k.

That being said, foreign media that 4 k is not in the way of "decline", broadcasters and content holders on the 4 k on the challenge in dealing with 8 k is still a problem, but if the delivery can complete 4 k infrastructure, 8 k may possess a certain component within three years, but now is too early to conclusions.
