Features of the TV with 4K
What is the basis of buying a TV? The main argument, of course, will be the visual perception of the picture. Modern manufacturers offer a new "chip" - 4K TV, which implies a fantastic resolution.

It's all about clarity
To meet the growing needs of progress, in 2002, the development of the idea of creating a new digital standard began: Digital cinema initiatives (DCI). Further developments led to completely new high resolution specifications - 2K, and a little later, 4K. Before that, everyone was familiar with high-definition views:
- Full (Full) HD has a 1080p image breakdown;
- 1080i - here is already interlaced;
- 720p (HD Ready).
In contrast, a 4K device is already a uhd-TV,which will transfer an Ultra HD image with active pixels. The resolution will reach the parameters of 3840 x 2160 p. In the image with 4K is involved whole 8 million pixelsthat will make the picture on the screen 4 times more realistic, and its resolution will increase to 4096 × 2160 r.
On any home TV marked with Ultra HD now it will definitely be 4K. Such a technique can now be hung in any apartment, another question: is it really worth doing it? In general, based on the parameters of clarity, it is possible to give such general recommendations for the purchase of televisions.
- With a three-meter distance from the telepanel to the viewing point, the screen with a resolution of 720p will perfectly fit - the picture will seem just perfect.
- 1080p can be well rated on screen with a minimum of 77 inches. And if the viewing distance is less than three meters, then a 60-inch screen will suffice.
- If a person sees the pixels on the screen of 50 inches and with a resolution of 1080p, while being from the device at a distance of 10 meters, then in this case, of course, can not do without 4K.
So choose what resolution is betterfollows from the conditions of watching TV.
4K TV
In practice, it is very difficult to catch the difference between 4K / UHD resolution and 1080p / HD - for the human eye, both look exactly the same (especially when viewing HD and Blu-ray formats). Differences become apparent in the following cases:
- when viewing a detailed image;
- on TV with a large diagonal;
- at a short viewing distance.
Users say: the difference is not so sharp that it catches the eye, as is obvious, for example, in computer graphics. Usually the difference in resolutions is noticeable if the screen is already 80 inches, and the viewing distance is at least two and a half meters.
The advantages of 4K TV
What can similar devices? Bonuses are obvious.
- The quality of the video will not differ from the picture outside the window - everything is extremely realistic and clear. Even the smallest details are not blurred and not lost.
- In the latest similar models of TVs in 2016 (and the release of such devices began two years earlier) is always present Smart TV function. This makes them convenient for surfing the web.
- Innovation and gamers will appreciate. The picture on the screen of such a TV device is as close to reality as possible (what else do gamers need,read in our article about choosing a tv for ps4).
- A similar screen will do for professional photographerswho will be able to view the fruits of their work in high resolution.
Format flaws
Before buying a vehicle with such capabilities, you need to familiarize yourself with the following minuses.
- Most of the modern TV channels still work even in 720p format, so it’s impossible to appreciate all the high-definition charms. And moreover, the idea will not succeed even in the coming years, because under such technology it will be necessary to modernize all technical equipment.
- The Internet also does not abound with 4K content (streaming television is no exception).
- The 4K panel turns out to be more expensive than its counterparts with absolutely the same functionality (on the order of 150-200 dollars).
- Gamers will also have to be disappointed: neither the Xbox One nor the PS4 still support this format, so you will have to dwell only on online offers (there are not many of them either).
- All similar models - led tvswhose color rendition and contrast are inferior to plasma. However, such a preference is a matter of taste and habit.
In most cases, the purchase of a 4K TV is an unnecessary waste of money, especially if it is planned for home use. It turns out that, in fact, an expensive and modern equipment has been acquired, but in practice it is unlikely to be able to evaluate all its charms.
The relevance of the HDMI standard for 4K
Determined for future buyers when choosing a TV should pay attention to availability of HDMI port in version 2.0. Can I transfer 4K via HDMI 1.4? Yes, but the frame rate will be 30 frames per second (30 Hz).
At the present stage, this will be enough, but progress does not stand still - very soon the television will switch to the transmission frequency of 50-60 frames per second. HDMI 2.0 is just capable of increasing such bandwidth in order to make the video even more realistic.
Overview of popular 4K TVs
Those who want to buy such a TV for the home can hardly be stopped by shortcomings. Further review will tell you how to choose the best model for yourself from the offers on the market.
Most first models Such options were very expensive: they were offered only by Sony and LG for the price of at least $ 30,000. Samsung went even further, releasing the TV for $ 55,000. Today, prices have fallen substantially. 4k TVs in 2016 occupied a special place in sales ratings, highlighting the best in their ranks for home use. There are plenty to choose from!
- The cost of Sony KD-55XD8577 will be 120,000 rubles. The 55-inch screen provides 1000 hertz sweep capability. Also, the TV provides AndroidTV, 4 HDMI ports and 3 USB ports.
- The LG 60UF771V has the same price. However, there are only 200 hertz spreads and three HDMI and USB inputs each. The only thing that confuses is the device works on web OS (but it is quite possible to put up with it).
- The South Korean leader also began to produce quite affordable 4K models. The cost of the Samsung UE60KU6000K is the same as that of the previous models, however, there is a SmartTV function here (it goes through its own Tizen operating system and has its own application store). Also, there are two yusbi ports (HDMI has three). There is also Wi fi, so the equipment is quite decent.
- It should be noted two more options from LG. LG 60UH620V - one of the most affordable in a similar category (the price is 95,000 rubles, there is Wi fi, SmartTV, 3 HDMI and 2 USB ports). The LG 60UF670V is a bit more expensive (100,000 rubles) and with minimal configuration (2 HDMI ports, 1 USB and the lack of SmartTV) pleases with a juicy and bright picture and stunning sound.
Beyond 4K horizons
The format in question is not the ultimate dream. Development and approbation is underway. 8K systems (Super Hi-Vision). It will be clearer than the last format 16 times. On this screen, you can fit 33 million pixels. Are modern technologies ready for such a breakthrough? Of course not. Only one Japanese government channel, NHK, declared its desire to switch to such a broadcast.
In fact, the difference in color will be noticeable only on huge screens. Device with a diagonal of less than 84 inches she just won't catch it. This casts doubt on the demand for such an idea on the market, especially if we assume an unrealistically high cost of equipment.
Summarizing what has been said, it can be noted that it is not so important on which particular 4K model the buyer chooses - Samsung or LG. If he has a large dwelling space, then, of course, such a purchase will be quite reasonable. But in most of our small apartments, the difference between previous generations of LCD TVs will not be so obvious.
