What is a "4K" and how much is in pixels
Before you decide on what it means to 4K resolution in the electronics world, let us remember that all modern digital screens composed of minute particles, "atoms" of the image, called pixels. The amount of these particles along the length and width is maximal resolution display. Alas, early models of the 90-ies of XX century due to the low value of this indicator could not give contrast and juicy picture. But by the early 2000s there was a first generation of monitors, has the support of resolution Full HD (1920 pixels in length and 1080 in width). This was followed by a wave of inventions, while in 2005 has not been presented 4K format. So what is it? Imagine a screen with 4000 pixels in length. This will be the hallmark characteristics of interest to us. But not so easy as it might seem at first glance ...
The difference between 2K and 4K seems to be not so large, but not for experienced moviegoers!
4K resolution standards for television screens and monitors
Yes, we are considering the technology has more and more subtypes, referred to as standards. The most common by far are:
- Ultra HD - the "compact" from the available options. It has a resolution equal to 3840 × 2160. It is with this variation, we often have to deal and acquiring game 4K monitors and other equipment of this kind;
- Wide-screen - it has a usual length of 4096 pixels, but the adjustment is inferior previous version - only 1600 points. It is used when creating movies;
Despite the low performance, wide-screen mode allows you to see the most detail on the screen
- WQXGA (DCI) - the format used in photo and video. It has averaged resolution - 4096 × 2160;
- Full-Frame - if this expert was asked, "What is the resolution - 4K", then most likely he would choose this option. Think about it, in terms of 3072 high and 4096 long, what else is necessary for happiness?
This decision is the quintessence of all the stages of development and implementation of the digital format
NOTE! (Click to see)
In addition to a wide standard among fans kinososmok existing academic and kashetirovanny formats created specifically for the film 35 mm wide. In everyday life, you are unlikely to use them, but if you feel the talent of the operator, you can try to experiment.
The devices work with images in 4K
The world market has learned that it is - 4K image quality -13 years ago, but not all the electronics is ready for such a large-scale change. Gradually UHD technology could penetrate virtually all electronic devices associated with the image - 4K monitors from Dell, BENQ, LG or widescreen TVs from Samsung and Philips now nobody surprise. We suggest to consider the most common devices with support for resolutions of 4000 pixels.
From huge screens to compact smartphones - where only this format can not be found!
4K TV - smart features and high price
Although television standard UHD TV was only adopted in 2012, the first development of the TV with a digital picture sverhchotkoy began in 2004 through the efforts of the company NHK. Since then, the world had seen dozens of different models, from simple budget versions to ultramodern flagships with an arsenal of advanced features.
If you decide to purchase a 2019 cost-effective, but the productive apparatus, it is necessary to look at the products of the brand LG (For example, model or 43UK6390 49UH619V) and 4K TVs from Samsung (UE43NU7100U or UE46MU6100U bring many pleasant impressions).
Keep in mind that such equipment will require a lot of space in the room
Well, if you want to become the owner of a new and better product (while having enough money), the Sony RD-75XF8596 or Samsung QE75Q8CAM be what the doctor ordered.
Note! Unfortunately, at the moment in Russia is supported not so much the content, made with Ultra HD-technology. And if when searching for a movie or TV series you will be able to receive data free of charge, the TV will be purely commercial in nature, demanding a monthly pay per view.
4K monitor for your computer - tech dream true gamers and designers
Any lover of computer games and IT-specialists confirmed that the image quality affects the working and entertainment processes no less than the performance of your PC. And if your monitor diagonal 27 inches or more does not support 4K, you are unlikely to get proper pleasure in testing the next shooter, or view a new video on Blu-ray-supported.
Due to the widespread development, in 2019 a similar device can afford almost any user. Having carefully studied the budget segment to identify samples such techniques as a masterpiece from ultraekonomichny Samsung - 4K monitor U28E590D or less popular but more productive and "fancy" product of AOS - U2879VF.
U28E590D model is ideal for a first acquaintance with the digital standard - cheap and stylish!
For the more affluent and demanding readers Tehno.guru recommends not to pass such instances as a 4K monitor from ASUS code "name» MX27UC or uncompromising gaming solutions presented by Acer - Predator XB321HKbmiphz.
It takes only one look at this miracle of technology, to realize that it is designed for long hours of battle behind the keyboard or gamepad
Other devices with UHD support - when one has little screen
Do you think that by buying yourself a new TV and a 4K monitor from LG or the Samsung, you will uncover the full potential of modern development? And here and there! Not only the large output has got support for Ultra HD format, it is subject to, and mobile devices, and video cameras. A good example is the flagship smartphone from the Japanese company Sony - Xperia XZ Premium and XZ2 Premium, combining the phenomenal performance from our interest-resolution display. Also, more and more popular acquires amateur shooting in UHD (though camera prices with an appropriate functionality is still "bite" noticeable).
Buying such powerful equipment, beware: in addition to the merits, it also reveals the interior and exterior of the shortcomings
Device requirements, supports 4K resolution
Since the subject of our review is rather impressive "dimensions" for it to work properly need powerful options, because only the best monitors and TVs support 4K. So what to look for when selecting in the first place?
- Aspect ratio should be 16: 9, if you see other values - hence the product in front of you in another category.
- The specification must be specified upconverter necessary to scale the image in the case of a simple Full HD 4K monitor or TV.
- Have at least one HDMI-input to appropriate support playback modes.
- And finally, the minimum acceptable resolution of 3840 × 2160 is recognized.
The apparatus must also be capable of processing a color space ITU-R BT.709 or higher, otherwise the image will blokloy
Finally, let's look at the main advantages and disadvantages of 4K:
| strengths | Weaknesses |
| Maximally detailed and sharp image | The high cost of devices |
| Correct display of the entire spectrum of colors | A limited amount of content on the territory of Russia |
| Reduced eye fatigue when viewing due to the high frame rate | Not every user will be able to fully tell the difference between Full HD and Ultra HD |
How long it will be relevant resolution of 4K
That's all. We hope our mini-excursion allow you to better understand what it is - the image in 4K. Despite the advent of 8K, and similar standards, they will not soon be able to fully occupy the minds of buyers. But the subject of our review will maintain your weight and significance at least the next 5-7 years, so that the prospects for the most optimistic, both literally and figuratively.
