Almost all new TVs and projectors have the power to decode HDR, or excessive dynamic vary, video. Normally, HDR content material seems to be higher than non-HDR materials, although a person show’s capacity to cope with the additional knowledge can differ drastically. 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 usually supply just one or two.
Thankfully, all HDR shows can play HDR content material — simply not all the time in the perfect format out there. This is what to bear in mind when looking for a brand new TV or deciding which streaming service to make use of for a film or present.
The fundamentals
These photographs try to illustrate, in your normal dynamic vary display, what HDR can do on HDR shows. The highest left reveals how the picture seems on an SDR show, tuned so the shadows are seen. Discover how the highlights within the clouds are “blown out,” that means they lack element. The higher proper reveals the HDR model with element preserved within the clouds. The decrease left reveals 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 best way HDR is used within the film or TV present have a higher impression 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 can look higher than one that does not. This is a tour of the HDR panorama at present.
- Every thing helps HDR10, however many TVs and sources will even have at the least 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 actual 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 vivid and darkish areas of a picture, making a higher “dynamic vary” than non-HDR content material (i.e., just about all the pieces you have 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 potential 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 might 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 out there, together with films, TV reveals and even video video games. Chances are high your favourite new packages already help HDR.
HDR10
- Supported by all the pieces.
- 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 all over the place. Each HDR TV can decode it and each HDR streaming machine helps it. Almost all HDR content material consists of an HDR10 model, generally alongside extra superior codecs equivalent to Dolby Imaginative and prescient, which we’ll talk about shortly.
HDR10’s principal limitation is its “static” metadata, that means a single HDR “look” is utilized to a whole film or present. That is nonetheless higher than SDR, however it would not permit very vivid or very darkish scenes to look their best possible inside the identical movie. This one-size-fits-all method works, however 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 whole soccer crew to put on the identical measurement shirt. It would match the quarterback and look OK on the large 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 out there with streaming content material and on 4K Blu-ray.
HDR10 Plus
- Championed by Samsung.
- Dynamic metadata.
- Doubtlessly higher picture than vanilla HDR10.
As you might have guessed from the identify, 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 data 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, possible for related causes. Nonetheless, Epson, TCL, Hisense, Roku and others supply HDR10 Plus compatibility.
It is just a little arduous 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 regular dynamic vary picture on a regular dynamic vary display. 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 knowledge.

Dolby Imaginative and prescient and Dolby Imaginative and prescient 2
- Doubtlessly the perfect picture high quality of all of the codecs.
- Much less content material out there 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 you could find 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 in the event you positioned an SDR and HDR TV side-by-side.
The draw back of Dolby Imaginative and prescient is that producers need to pay Dolby to make use of it. In return, Dolby helps them optimize their TVs to look their finest with DV content material. For some corporations, that is a simple method to enhance image high quality. Bigger producers — like a sure Korean model that begins with the letter S — want to put money into their very own HDR codecs as an alternative, thanks very a lot.
After HDR10, that is the preferred HDR format, however that does not imply it is common. Samsung is the largest holdout, for causes talked about above. Usually talking, if an organization would not help Dolby Imaginative and prescient, it possible helps HDR10 Plus, although some corporations help each. There’s much less Dolby Imaginative and prescient content material than there may be vanilla HDR10 content material, however big-budget films and TV reveals 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, for my part, is non-compulsory movement smoothing, which might permit administrators or showrunners to clean scenes they think about too juddery, equivalent 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 need to see the way it’s carried out 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, after all, 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. Not like the codecs we have mentioned to this point, it is truly backward-compatible with SDR TVs. One sign that works on each older TVs and newer ones is a large deal for broadcasters. As you’ll be able to think about, it isn’t with out drawbacks — primarily in the case of 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 vivid white. The horizontal axis is the bodily brightness popping out of your tv. An SDR TV would see the HLG sign and assume 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 data as a bodily brighter a part of the picture (i.e., how HDR usually works).
There’s already huge TV help. Content material continues to be within the early phases, nevertheless. If you may 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 quite a lot of content material to this point. It is free and fills an essential area of interest, however it’s been years because it got here out and it hasn’t been extensively adopted. Some telephones can file HDR by way of HLG, which you’ll playback on HLG-compatible shows.
For more information, and why it is so completely different from different strategies, try our explainer on hybrid log gamma.
Superior HDR by Technicolor (SL-HDR1, 2 and three)
- Not extensively supported.
- Every “taste” has its personal area of interest.
- Unlikely to see huge adoption
Technicolor’s Superior HDR is available in a number of flavors: SL-HDR1 is just like HLG in that it is totally 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 robotically created from the HDR sign.
Content material is restricted to some NextGenTV broadcasts. It is unlikely it can get huge acceptance amongst streaming corporations.

There may be just one. Or three. Or possibly 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 provide doubtlessly higher picture high quality. All HDR ought to look higher than older SDR content material (or the non-HDR model of recent content material). NextGenTV continues its sluggish rollout. The potential of free over-the-air HDR continues to be there, however at this level it is within the palms of the person channels and channel homeowners as to how a lot HDR they wish to broadcast.
Usually 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 finest TVs. The excellent news is that almost all of latest reveals, films and even many video games, all help HDR in a method or one other. Most TVs and projectors do as nicely, although after all, some higher than others.
