Understand the peculiarities of HDR technology, and we are looking what is HDR TV, manufacturers are actively being implemented in modern TVs, and we find out that it is necessary to prefer: HDR support or a higher resolution.
WHAT IS HDR TV?
Modern technology is so firmly established in our lives, it is sometimes difficult to understand in all their diversity. For example, choosing a TV, you have to pay attention to many parameters, some of which may perplex the unprepared buyer. In this article, we will talk about HDR technology, which has become extremely relevant in the past year and a half.
In practice, its implementation prior to 2016 it was the prerogative of certain TV models and the corresponding content was too little. Fortunately, during the year the situation began to change: more and more manufacturers equip their TVs to support for HDR. Manufacturers of video game consoles have also implemented support for technology in the updated model. Sony has gone a step further and included HDR support the original PlayStation 4 by a software update.
Most importantly – appeared and continues to appear relevant content that can be revealed on the HDR-enabled devices.
So is it worth all the fuss around HDR investment buyers money to a compatible device?
HOW DOES IT LOOK?
Let’s try to understand and begin to explain the essence of technology.
Any TV is characterized by indicators of contrast and color accuracy. Contrast affects how bright and dark colors can show the device while keeping them visible to the viewer. Color accuracy, in turn, refers to how close to the real colors will be displayed on the screen.
It is interesting that the majority of potential buyers if they offer a choice of TV with a high-resolution TV with a lower resolution, but higher contrast, choose the second. This richness and variety of colors are a priority in the selection. Thus, the brightness of the picture still remains rather higher resolution 4K. Customers choose eyes.
WHAT IS THE ESSENCE?
What is HDR TV? HDR technology (High Dynamic Range), or an extended dynamic range, allows a choice described above is even more obvious: it makes the light colors lighter still and dark – darker. HDR increases the color range and maximum contrast, which makes the image more profound and intense. Standard colors – red, blue and green – get additional shades and combinations thereof, that has a direct impact on the quality of the image.
Hand in hand with the HDR technology goes WCG (Wide Color Gamut). Last further expands the range of available colors. The audience never before faced with these technologies, will be pleasantly surprised at how increasing the number of shades of the same seems to be the usual colors.
It is important to understand that the HDR technologies introduced in modern TVs and devices connected to them, seriously differs from what has for some time present in the cells of our smartphones.
For HDR television technology enhances contrast and palette of available colors to make the image on the screen is more realistic to show it in the natural colors. HDR technology in the cells, in turn, is used to combine multiple images at once for the best picture, which combines the most successful elements of all made shots. Thus, the difference between the two turns HDR principle.
AS IMPLEMENTED?
What is HDR TV? HDR technology consists of two integral parts: the display and content.
In fact, the TV – this is the most simple of the two. It is required to be able to highlight certain areas of the screen more clearly than it does its conventional counterpart, not having the support of the HDR.
Everything is much more complicated in the case of the content, which should have the support of the HDR, to display dynamic range on the screen. Most of the films, many series, taken in the last decade, have the support of the HDR. Also, it can be added without any artificial inclusions in the original image. The fact that the main obstacle to the HDR-content to your TV becomes only the data transfer.
Video created with the use of high dynamic range is compressed to then be transferred to your TV, computer or another device. As a result, the user sees the best image, which is trying to reproduce it using a display built into it technologies and systems to improve image quality.
Thus, only the content from certain sources will be displayed with the HDR present, because your TV will receive additional metadata that will tell him exactly how you want to display each specific scene. Of course, this means support for the playback device technology.
In addition, there are certain requirements for equipment. Not only your TV but also a player or set-top box must have a connector HDMI version 2.0 or later. Most of the equipment issued from 2015 to the present, has the support of the standard HDMI 2.0, which can be software upgraded to HDMI 2.0a. The latest version of the standard required transferring that same metadata mentioned above.
The producers have already decided to assign TVs having 4K resolution support and HDR technology, UHD Premium Certificate. His presence should pay attention to when buying. Also, note that the format of 4K Blu-ray also has default support for HDR.
SUMMARIZE
Of course, HDR technology in televisions is not as vital as it is presented with manufacturers, but that it is now a major force in the industry. What is HDR TV? The race for higher resolution 4K receded into the background, giving way to an expanded dynamic range.
Although the best results will be achieved by combining two advanced standards at this stage it is preferable to choose a TV that supports the HDR, if you are not willing to pay for having a higher than 4K resolution. The picture quality when using the appropriate content will surprise you in any way. The eyes do not deceive: brighter, more saturated colors, as well as their variety, will be rather than the presence of ultra-high-resolution matrix.
Thus, buying a new TV at the end of 2016, it is desirable to attend to at least the presence of HDR support, and higher resolution 4K still remains enjoyable, but still complement, that is too much effect on the final purchase price, but does not bring the same emotions.
