Everything you need to know about HDR about TV

In the world From new TVs, goals are always moving. As soon as you feel safe to shake a new set, there is another reason to endure. First there was 3D. Then 4K. Let’s not forget about OLED and quantum points, then more expensive 4K and more expensive OLED. This year is no exception, as another new technology offers another reason to hold your horses. It’s called HDR video, which is short for a “high dynamic range”.

HDR is not for extra pixels. Each set capable of processing HDR video can now show 4K video. Instead, HDR makes images with many different lights and dark ones that look better on your screen. It’s great! You completely want it. But like most nascent technologies, barriers are full of early adoptive parents. From high prices to shortage of video sources, there are many things to consider before you enter HDR.

What is HDR video?

If the abbreviation “HDR” sounds familiar, this is because you have seen it as a setting in the camera of your smartphone. The results there are not great, which means you probably think HDR is nasty. For stationary photography HDR is convenient (if too used) solution to a common problem: it reveals details in light and Dark stage areas, usually by capturing multiple images at different exposures and uniting them. The problem is that such pictures often they look an aerograph and fakeS

The HDR video is different. It looks very realistic, with gradations and shades closer to what is visible in real life. It can become bright enough to simulate the light reflecting chrome and dark enough to look like oil smooth. In both cases, you still see fine details and subtle shades. HDR does not fake contrast with stupid filters and strange effects of the halo. Instead, he uses new panel technologies with a wider color palette in a concert with a specially coded video.

For this reason, you need a specific type of TV to see HDR video properly and you also need a specific type of video source. In the best case, you will see deeper and more accurate colors, and the light effects will look more lively.

How do HDR TVs differ radically?

HDR is not tied to a specific type of display technology, but almost all HDR kits have been shared by several features so far. Vizio, Sony, Samsung, Panasonic, LG, TCL and Hisense have TVs capable of HDR, which are essentially super -powered LCD 4K TVs. These kits can get really Bright — bright enough that watching a screen sun or explosion can make you narrow. The backlighting systems of these panels hide up to more than 1000 Nits–for comparison, most LCD HDTV exhibits about 300 or 400 nits. Why so bright? With such high peak brightness, the contrast between light and dark (or light and shorter) areas of the stage is more pronounced.

Also, most HDR TVs are not OLED kits. They use LCD panels as they can become much more than OLED. However, since OLED has no backlight systems (each pixel is switched on and excluded individually to OLED), they can become much smaller and therefore produce deeper black ones. Earlier this month, LG and Panasonic have announced new 4K OLED TVs that can show HDR video.

What about the colors? Are they better at HDR TV?

Yes! There are more colors on these 4K high -end TVs.

This is because both the content and the TVs move far beyond the color space and the bitter depth of traditional HDTV. To display the HDTVS colors adheres to a 25-year specification called Rec. 709. This is an 8-bit color space recommendation made by a television commercial group. It is old as Windows 3.0 and Season SimpsonsS This is archaic and supported throughout the HDTV era. We now have a new specification: 4K TVs and content will strive for 10- to 12-bit Rec. Color space 2020, which is more than 60 times more than different color combinations than RC. 709. In fact, more than a billion of them. Rec. The 2020 color range is even wider than the DCI-P3 color space, defined for professional digital projectors (which is also much wider than Rec. 709).

From the photos to the mastery to the distribution to display, we are talking about the end-to-end pipeline that creates a far better picture. Content can be mastered to take advantage of the wider color space, the extra metadata is directed to a TV that can be determined how it looks and technologies to adjust the colors such as Quantum points He can help him show up accurately. The combination of 4K resolution, exceptional brightness, improved contrast and more colors will be what makes the HDR video look spectacular-even if the trick “HDR” itself is just a part of the sauce.

Man, how do I make sure my new TV is doing all this?

There is a badge now! UHD Alliance, a group of television manufacturers, content providers and distribution companies, will begin to print approval to Ultra HD Premium for certain TVs. These badges will be reserved for “five -instrument players” of the television world, sets that provide a combination of blades resolution, a high dynamic range and a very wide color range.

In order to qualify, the TV must have a display resolution of at least 3840×2160 (this is 4K), maintain a 10-bit color, can process sources that use RC. Color space 2020 and can show at least 90 percent of the DCI-P3 color space. In terms of dynamic range, Ultra HD Premium Badge holds both LCD and OLED displays. For the LCD, a qualifying TV must have a top brightness higher than 1000 nits and a black level less than 0.05 nits. In order for OLED to qualify, it must have a peak brightness of at least 540 nits (remember that OLED cannot become super bright) and a black level less than 0.0005 nits (remember that OLED can become super dark).
