Practically all new TVs and projectors have the power to decode HDR, or excessive dynamic vary, video. Generally, HDR content material appears higher than non-HDR materials, although a person show’s capacity to take care of the additional information can differ vastly. There are a number of HDR codecs, together with Dolby Imaginative and prescient, Dolby Imaginative and prescient 2, HDR10, HDR10 Plus and HLG. Most shows can solely decode one or two of those. Likewise, streaming companies and 4K Blu-rays sometimes supply just one or two.
Happily, all HDR shows can play HDR content material — simply not all the time in the perfect format accessible. This is what to remember when searching for a brand new TV or deciding which streaming service to make use of for a film or present.
The fundamentals
These photographs try and illustrate, in your normal dynamic vary display screen, what HDR can do on HDR shows. The highest left exhibits how the picture seems on an SDR show, tuned so the shadows are seen. Discover how the highlights within the clouds are “blown out,” which means they lack element. The higher proper exhibits the HDR model with element preserved within the clouds. The decrease left exhibits the identical picture adjusted to protect the highlights, which causes the shadows to vanish. HDR shows displaying HDR content material have a wider dynamic vary — the distinction between the brightest and darkest components of a picture.
In CNET’s TV and projector opinions, we have discovered that each the capabilities of the TV itself and the way in which HDR is used within the film or TV present have a larger affect on picture high quality than the particular HDR format. In different phrases, simply because a show helps a “higher” HDR format does not imply it is going to look higher than one that does not. This is a tour of the HDR panorama as we speak.
- Every little thing helps HDR10, however many TVs and sources will even have no less than one of many different codecs.
- Dolby Imaginative and prescient and HDR10 Plus can look higher in particular methods in comparison with HDR10. All will look higher than non-HDR, normal dynamic vary content material.
- One format would possibly look “higher” than one other on paper, however in the true world, picture high quality relies upon way more on the TV’s general efficiency and the way the content material was made.
Most new TVs can show HDR content material, which preserves extra element in each vibrant and darkish areas of a picture, making a larger “dynamic vary” than non-HDR content material (i.e., just about all the things you’ve got ever watched). That older format is now referred to as SDR, or normal dynamic vary. On an HDR TV, HDR content material can look way more punchy and vibrant than conventional video.

The dynamic vary of what is captured by the digicam (left) and what’s attainable on SDR and HDR shows.
Simply having an HDR TV is not sufficient; you additionally want HDR content material. With out it, the TV would not have a lot to work with. It could nonetheless look good and might artificially broaden SDR content material for a slight enchancment, however to get essentially the most out of HDR you want content material designed for it. Fortunately, there’s now loads accessible, together with films, TV exhibits and even video video games. Chances are high your favourite new packages already help HDR.
HDR10
- Supported by all the things.
- Higher picture high quality potential than SDR, however maybe not so good as HDR10 Plus or Dolby Imaginative and prescient.
- Static metadata.
HDR10 is about as near a common normal as we have. As a result of it is free for producers to make use of, it is supported nearly in all places. Each HDR TV can decode it and each HDR streaming machine helps it. Practically all HDR content material consists of an HDR10 model, typically alongside extra superior codecs comparable to Dolby Imaginative and prescient, which we’ll focus on shortly.
HDR10’s essential limitation is its “static” metadata, which means a single HDR “look” is utilized to a complete film or present. That is nonetheless higher than SDR, nevertheless it would not permit very vibrant or very darkish scenes to look their best possible throughout the similar movie. This one-size-fits-all method works, nevertheless it prevents each the content material and the TV from reaching their full potential. Dynamic metadata, which most different HDR codecs use, addresses this limitation.
Static metadata is like forcing a complete soccer workforce to put on the identical measurement shirt. It’d match the quarterback and look OK on the massive linebacker and tiny kicker, however everybody would look higher in shirts sized for them.
HDR10 is not backward-compatible with SDR TVs, so it is no good for broadcast. You may discover it accessible with streaming content material and on 4K Blu-ray.
HDR10 Plus
- Championed by Samsung.
- Dynamic metadata.
- Probably higher picture than vanilla HDR10.
As you’ll have guessed from the title, HDR10 Plus is just like HDR10, however with just a little plus. The “plus” on this case is dynamic metadata, which improves on HDR10’s static model. Which means on a per-scene — and even per-image — foundation, the content material can present the TV with all the knowledge it must look its best possible.
Whereas there are specific charges for producers to make use of HDR10 Plus, they are much lower than what Dolby expenses for Dolby Imaginative and prescient. As a result of it is from Samsung, it is extremely unlikely there’ll ever be an LG TV with HDR10 Plus. Sony is one other holdout, probably for comparable causes. Nonetheless, Epson, TCL, Hisense, Roku and others supply HDR10 Plus compatibility.
It is just a little laborious to see on this graphic, however discover how the frames on the proper present completely different ranges of brightness within the sky. This instance makes use of a normal dynamic vary picture on a normal dynamic vary display screen. HDR10 Plus’s dynamic metadata permits filmmakers to optimize how every shot or scene is displayed. HDR10, in contrast, makes use of static metadata — a single setting that should function a compromise between the darkest and brightest scenes.
On the content material aspect, there’s Amazon, Apple TV, Disney Plus, Paramount Plus and Netflix, amongst others. Remember that simply because an organization or streaming service helps HDR10 Plus does not imply that each product or present/film is appropriate with or has HDR10 Plus information.

Dolby Imaginative and prescient and Dolby Imaginative and prescient 2
- Probably the perfect picture high quality of all of the codecs.
- Much less content material accessible than with HDR10.
- The de facto “step up” HDR format.
Dolby Imaginative and prescient, like HDR10 Plus, can have dynamic metadata. Streaming companies together with Netflix, Amazon, Vudu and Apple TV help it, and yow will discover it on some 4K Blu-rays. Some Dolby Imaginative and prescient options — together with dynamic metadata and colour dealing with — are non-compulsory in HDR formatting for NextGen TV, although over-the-air HDR content material stays uncommon.
That is an approximation, utilizing two SDR photographs, of what you’d see when you positioned an SDR and HDR TV side-by-side.
The draw back of Dolby Imaginative and prescient is that producers must pay Dolby to make use of it. In return, Dolby helps them optimize their TVs to look their greatest with DV content material. For some firms, that is a simple manner to enhance image high quality. Bigger producers — like a sure Korean model that begins with the letter S — desire to spend money on their very own HDR codecs as a substitute, thanks very a lot.
After HDR10, that is the preferred HDR format, however that does not imply it is common. Samsung is the most important holdout, for causes talked about above. Typically talking, if an organization would not help Dolby Imaginative and prescient, it probably helps HDR10 Plus, although some firms help each. There’s much less Dolby Imaginative and prescient content material than there’s vanilla HDR10 content material, however big-budget films and TV exhibits nearly all the time embody it.
Introduced at CES 2026, Dolby Imaginative and prescient 2 introduces a number of new options. Probably the most controversial, in my view, is non-compulsory movement smoothing, which might permit administrators or showrunners to easy scenes they think about too juddery, comparable to quick pans. The format additionally consists of “content material intelligence” options that regulate a TV’s efficiency based mostly on ambient mild and the content material being proven. Midpriced and lower-end TVs will help the bottom model of Dolby Imaginative and prescient 2, whereas higher-end fashions will supply Dolby Imaginative and prescient 2 Max, which incorporates the motion-smoothing function. We’ll must see the way it’s applied as soon as TVs and appropriate content material arrive, presumably later this yr.
The excellent news is DV2 is appropriate with all present Dolby Imaginative and prescient TVs. Older DV TVs will not have entry to the brand new options, in fact, however the HDR and dynamic metadata will nonetheless work.
HLG
- From BBC and NHK.
- Free to make use of.
- Broadcast-friendly.
Hybrid Log Gamma was created by Britain’s BBC and Japan’s NHK. In contrast to the codecs we have mentioned up to now, it is truly backward-compatible with SDR TVs. One sign that works on each older TVs and newer ones is a enormous deal for broadcasters. As you possibly can think about, it is not with out drawbacks — primarily relating to image high quality. Like HDR10, HLG is probably going higher than SDR, however it could not match the image high quality of another HDR codecs. It is the format used for over-the-air HDR broadcasts.
A graphical illustration of an SDR and HLG sign. The vertical axis is the sign, from broadcast, cable or satellite tv for pc, for instance. “0” is black, “1” is vibrant white. The horizontal axis is the bodily brightness popping out of your tv. An SDR TV would see the HLG sign and suppose it was “regular,” displaying a picture with, maybe, higher spotlight element. An HDR TV that is HLG-compatible would perceive what to do with the HLG sign and present that brighter info as a bodily brighter a part of the picture (i.e., how HDR usually works).
There’s already vast TV help. Content material remains to be within the early levels, nevertheless. If you will get the BBC’s iPlayer (whether or not you are within the UK or utilizing a VPN), that service has HLG help. DirecTV and YouTube additionally help HLG, however there’s simply not loads of content material up to now. It is free and fills an necessary area of interest, nevertheless it’s been years because it got here out and it hasn’t been broadly adopted. Some telephones can document HDR through HLG, which you’ll be able to playback on HLG-compatible shows.
For more information, and why it is so completely different from different strategies, take a look at our explainer on hybrid log gamma.
Superior HDR by Technicolor (SL-HDR1, 2 and three)
- Not broadly supported.
- Every “taste” has its personal area of interest.
- Unlikely to see vast adoption
Technicolor’s Superior HDR is available in a number of flavors: SL-HDR1 is just like HLG in that it is absolutely backward-compatible with SDR TVs, permitting for one sign to rule all of them; SL-HDR2 has dynamic metadata like HDR10 Plus and Dolby Imaginative and prescient; SL-HDR3 makes use of HLG as a base, however provides dynamic metadata.
The trail to SDR and HDR in a single SL-HDR1 sign. The highest is the content material creation, the underside is what your TV will do with it. The SDR content material is routinely created from the HDR sign.
Content material is proscribed to some NextGenTV broadcasts. It is unlikely it is going to get vast acceptance amongst streaming firms.

There might be just one. Or three. Or perhaps 5
This is the tl;dr: HDR10 is the principle HDR format. Dolby Imaginative and prescient and HDR10 Plus are the step-up choices that supply probably higher picture high quality. All HDR ought to look higher than older SDR content material (or the non-HDR model of contemporary content material). NextGenTV continues its sluggish rollout. The potential of free over-the-air HDR remains to be there, however at this level it is within the fingers of the person channels and channel house owners as to how a lot HDR they wish to broadcast.
Typically talking, it is value ensuring any new TV you are contemplating helps both Dolby Imaginative and prescient or HDR10 Plus because the dynamic metadata could make a noticeable distinction, particularly on the greatest TVs. The excellent news is that almost all of recent exhibits, films and even many video games, all help HDR in a technique or one other. Most TVs and projectors do as effectively, although in fact, some higher than others.
