Everything You Need to Know About HDR for TV

In the world In the new TVs, the goalposts are always running. There is another reason to hold on as soon as you feel safe in a new set. Was at first 3D. Then 4K. Let’s not forget the OALD and quantum points, then cheap 4K and cheap OLED. This year is no exception, another new technology provides another reason to hold your horses. It is called HDR video, which is short for the “high dynamic range”.

HDR is not about additional pixels. Each set capable of handling the HDR video may already show 4K video. Instead, HDR looks better with different lights and dark expanding on your screen. It’s great! You want it completely. However, like most newborn technologies, obstacles for primary accepters are abundant. From high prices to lack of video sources, you need to consider many things before buying HDR.

What is HDR video?

If the “HDR” summary seems to be familiar, it is seen as settings on your smartphone camera because it is. The results are not great, which means that you probably think HDR is successful. For steady photography, HDR is a simple (extra used) for a common problem: It brings details to the light And The dark areas of a scene usually capture multiple images in different exposure and merge them. The problem is, this national picture is often Air brushd and fake lookThe

HDR video is different. It looks very realistic to see it with gradations and briefs near what is seen in real life. It can be brighter enough to mimic the reflected light from the chrome and the oil looks like slick enough. In both cases you still see fine details and fine shades. HDR is a fool filter and weird is not forged the contrast with the effects. Instead, it uses the new panel technology with a wide color palette in the concert with specially encoded videos.

That is why, you need a certain type of TV to watch the HDR video correctly and you also need a certain type of video source. In the best case, you will see more deeper and more accurate colors and the effects of light will appear for a lifetime.

How are HDR TVs basically different?

HDR is not bound to a certain type of display technology, but almost all HDR sets share a few features so far. VGO, Sony, Samsung, Panasonic, LG, TCL and Hycense all have HDR-capable TVs, which are mainly super-driven LCD 4K television. These sets may get Truly Bright — The onscreen that is brilliant enough to make you scwn you to scwn in the sun or explosion. The backlight systems of these panels crank more than a thousand Knit— Compare, most LCD HDTVs keep about 300 or 400 nets. Why so bright? With the brightness of such a high peak, the difference between the light and the dark (or light and light) regions of the scene is even more evident.

Also, most HDR televisions are not OALD sets. They use the LCD panel, as they can be much brighter than OLEDS. However, since OALDS does not have a backlight system (each pixel is turned on and off individually in an OALD) they may be more erotic and therefore can produce deep black. Earlier this month, both LG and Panasonic announced the new 4K OLED TV that could show HDR videos.

What about the color? Are they better on HDR TVs?

Yes! This high-end 4K has more colors on TV.

The reason for this is that both content and TV are moving far more than the color of the color space and the traditional HDTVs. To display the colors, HDTVs are on the 25 -year -old specification called REC. 709. It recommends an 8-bit color space made by a TV trade group. It is old as Windows 3.0 and a season is a SimpsonsThe It is archaeological, and it is supported throughout the entire HDTV era. Now we have a new space: 4K TV and content will take the target of 10-12-bit rack. 2020 color space, which represents more than 60 times than a combination of many distinct colors like a rack. 709. More than one of them. Rock. The 2020 color gumut is more spacious than the DCI-P3 color space defined for professional digital projectors (which is rack. Much wider than 709).

From filming to distribution to display, we’re talking about an end to the end pipeline that creates better pictures. The contents can be mastered to take advantage of the wide color space, pipe on HDR-enable TV to determine what it looks like, and color tuning technology such as Quantum point It can help to show properly. The combination of 4K resolution, extreme brightness, advanced contrast and more colors is that the HDR video looks spectacular-even though the “HDR” technique itself is only a part of the sauce.

Man, how do I make sure my new TV does everything?

There’s a badge now! A group of UHD alliances, TV manufacturers, content suppliers and distribution companies will begin to provide a “Ultra HD Premium” stamp with the approval of specific TVs. These badges will be reserved for the “five-sorganam player” of the TV world, sets that provide a combination of tack-holding resolution, high dynamic range and a very spacious color gum.

In order to qualify, a TV must have at least 3840×2160 (it 4K) display resolution, supports 10-bit colors, be able to handle sources that use REC. Able to show at least 90 percent of the 2020 color space, and DCI-P3 color space. In the case of a dynamic range, the Ultra HD Premium Badge integrates both LCD and OLED display. For an LCD, the brightness level on the top of an eligibility TV must be higher than 1000 nets and a black layer is less than 0.05 knit. In order to qualify for an OLED, it must have at least 540 Nit’s top brightness (remember OLEDs may not be super bright) and a black level is lower than 0.0005 nets (remember OAELDS Super Dark).
