HDR and 4K TV Review

Submitted by admin on Fri, 06/02/2017 - 13:17

On the question of HDR and 4K - what is the best answer for the consumer is unambiguous: HDR. Obviously, all discussion of HDR technology today is centered around the technology of 4K televisions. The reason for this is quite simple: a wide dynamic range is currently being developed and offered only on a commercial basis for the front edge of the television front and is therefore limited to using strictly in TVs with 4K.

In addition, all these additional pixels of the 4K Ultra HD displays certainly help in creating a clearer live image on the TV. If someone does not know what HDR standard is, then there is an opportunity to get acquainted with the parameters of HDR video.

However, between HDR and 4K display enhancements, HDR is a more visible and conspicuous parameter with much greater opportunities for development and improvement. 4K TV can have a maximum of only 8.29 to 9 million pixels (depending on how to specifically determine the resolution of 4K), and a larger resolution is likely to require a certain development time due to the huge amount of data, and in any case in the foreseeable future does not go beyond 8K resolution frame.

On the other hand, the wide dynamic range is still in infancy, and even in the short term (the next couple of years), it will have to develop steadily in terms of gradual increase in brightness levels, until they adequately correspond to reality, and with flowers one must also work with A much greater degree of accuracy.

In addition, in the ranges of specific technologies that determine the color and contrast in HDR video, there are huge variations of parameters that can be reworked. But most importantly, high-quality HDR when activated, immediately catches the eye on any TV screen.

While many viewers might have difficulty in distinguishing HD resolutions from 4K UHD on 4K small and medium televisions at a normal viewing distance, a picture with a wide dynamic range in 4K TV looks much better than with a standard dynamic range in any comparison sequence.



HDTVs are the standard that has been used for the past decade. Now it is difficult to go into the store and buy a TV that is not at least HD Ready, which means "capable of displaying a resolution of 1280 x 720 pixels (720p)". But the vast majority of modern TVs that you can buy are Full HD, which means "capable of displaying at a resolution of 1920 x 1080 pixels (1080p)."

The letter "p" in both versions means progressive, which means that the entire image draws each line of the frame sequentially, and such lines 720 or 1080 respectively. The alternative is the letter "i", which means interlaced (1080i is the HDTV standard). Odd and even lines are displayed alternately in each frame, resulting in a slight deterioration in image quality.

The term 4K refers to any display format with a resolution of about 4000 pixels horizontally. This is a little confusing, since at lower resolutions the format is recorded as the number of pixels in the vertical direction, i.e. 1080i or 720p.

UHD or Ultra HD is the same as 4K, except for one: it is more suitable for consumers and television, it also has a lower resolution of 3840 × 2160 pixels (2K) than 4K.

In this way:

(DCI) standard Digital Cinema Initiatives is a professional production standard that is the most common for digital production at a resolution of 4096 x 2160 pixels.
UHD-1, often referred to as 4K UHD or simply 4K, and sometimes as 2160p, which became standard for televisions that have a resolution of 3840 x 2160 pixels, which is four times the number of pixels in the Full HD format.

Most modern UHD-1 televisions do not use the wider DCI 4K aspect ratio, as it is not suitable for most TV content.

There is also a Full HD Ultra format, sometimes called 8K, it has a resolution of 7620 x 4320 pixels. On the Yandex Market there are several TVs that can boast such a screen resolution and flawless picture, but it is recommended to choose a Full HD Ultra TV with a diagonal of at least 85 inches. On a smaller diagonal you simply will not see all the splendor of the picture, which is possible on 8K.

In general, when you start looking for 4k content, you realize that it's really very small, you can even say - crumbs.
Even buy movies and then there is no possibility, because. Those 4K movies that are sold them can be counted on the fingers, and they have no genre of fiction, no action, nothing with a cool computer. Graphics. Mainly documentary and nature, in order to show the possibilities of 4K.
