In the world of the new TV, the goal is always moving. As soon as you feel safe with a new set, another reason to keep it appear. The first is 3D. Then 4K. We do not forget the oled and quantum dots, then cheaper than 4K and cheaper than OLED. This year is no exception, with another new technology providing another reason to keep your horse. It is called HDR video, abbreviated for “high dynamic range”.
HDR is not about additional pixels. Each set has the ability to process HDR videos that can display 4K videos. Instead, HDR makes the image with different lights and darkness look better on your screen. Great! You absolutely want it. But like most young technologies, a lot of barriers for those who accept early. From high prices to a video source, there are many things to consider before you buy HDR.
What is HDR video?
If the word “HDR” abbreviation sounds familiar, it is because you have seen it as a installation in your smartphone camera. The results are not great, that means you may think HDR smokes. For static photography, HDR is a convenient solution (if used in excess) for a common problem: it gives details in light. And The dark areas of a scene, usually by taking many images in different exposure and merged them. The problem is, such photos often Look at Airbrushed and fake.
HDR video is different. It looks very realistic, with an increase and nuance closer to what is seen in real life. It can be bright enough to simulate the light of Chrome and are dark enough to look like a piece of oil. In both cases, you still find good details and subtle shades. HDR does not fake contrast with stupid filters and strange aura effects. Instead, it uses new control panel technologies with a wider color palette during a concert with a special encrypted video.
For that reason, you need a specific TV to watch HDR video properly and you also need a specific source of video. In the best case, you will see the deeper and more accurate color, and the lighting effect will appear like the reality.
How is HDR TV basically different?
HDR is not associated with a certain type of display technology, but almost all HDR sets have shared a few characteristics so far. Vizio, Sony, Samsung, Panasonic, LG, TCL and Hisense all have HDR capabilities, basically a super -power 4K LCD TV. These sets can receive Actually Morning — enough to look at the sun or the explosion on the screen can make you squint. The backlight systems of these tables turn to more than 1,000 Nits— By comparison, most HDTV LCD offers about 300 or 400 nits. Why is very bright? With such a high maximum brightness, the contrast between light and dark areas (or light and lighter) of the scene is clearer.
In addition, most HDR TVs are not OLEDs. They use LCD panels, as they can be much brighter than OLED. However, because OLED does not have a backlight system (each pixel is on and off individually on OLED), they can be much darker, and thus creates deeper black people. Earlier this month, both LG and Panasonic announced the new OLED 4K TV that can display HDR videos.
What about colors? Are they better on HDR TV?
Correct! There are more colors on these high -end 4K TVs.
That's because both content and TV are moving far beyond the colorful space and bit depth of the traditional HDTV. To display colors, HDTV attaches to a 25 -year -old specification called Rect. 709. It is an 8 -bit color spatial recommendation made by a TV commercial group. It is as old as Windows 3.0 and the first season of Simpsons. It was ancient, and it was supported in the entire HDTV era. Now we have a new specifications: TV and 4K content will target Rect 10 to 12 bits. Color space 2020, representing more than 60 times combined with separate colors like Recs. 709. More than one billion of them, actually. Rec. 2020 Color Gamut is even wider than the DCI-P3 color space that is determined for professional digital projectors (also much larger than record. 709).
From filming to ownership to distribute to display, we are talking about a pipe from the beginning to the end to create a much better picture. The content can be proficient to take advantage of the wider color space, the additional super data is included in HDR capabilities to determine how color adjustment technologies and color adjustment technologies like quantum Can help it display correctly. The combination of 4K resolution, extremely high brightness, improved contrast and more colors will be what makes HDR video look spectacular — even if the “HDR” trick is just Part of the sauce.
The man, how to make me sure my new TV does all that?
There is a badge now! The UHD Alliance, a group of television producers, content providers and distributors, will start releasing the “Ultra HD Premium” mark for the approval of certain TVs. These badges will be reserved for the “five tools players” of the TV world, the set provides a combination of Sharp resolution, high dynamic range and very wide color.
To be eligible, the TV must have a display resolution of at least 3840×2160 (that is 4K), supporting 10 -bit color, can handle the sources using Recs. Color space 2020 and can display at least 90 percent of DCI-P3 color space. In terms of dynamic range, the Ultra HD Premium badge may contain both LCD and OLED screens. For LCD monitors, eligible TVs must have a maximum brightness level higher than 1,000 nits and black levels below 0.05 nits. For OLED to be eligible, it must have a maximum brightness of at least 540 nits (remember that OLED cannot have super bright) and the black level below 0.0005 nits (remember, OLED can become super super dark).
