What is HDR10+? What you need to know

Another day, another HDR format to get to grips with. Here’s your guide to the latest in HDR10+.

Back in 2017, Samsung and Amazon announced a new format of high dynamic range technology called HDR10+. It claimed to improve on the industry standard HDR10 effort by adding a layer of extra, scene-by-scene information to help TVs handle HDR playback better.

Given how complicated and messy the world of HDR already is, reactions to HDR10+ largely boiled down to journalists burying their heads in their hands and consumers burying their heads in the sand.

Since then, perception of HDR10+ has shifted – for better or for worse – from unwanted fringe complication to a promising player. So here’s what you need to know about the latest variant of HDR for TVs and in the case of the Samsung Galaxy S10/S10+, smartphones, too.

The HDR10+ Alliance


Early in the life of HDR10+, the only announced support had come from Samsung on the hardware side and Amazon Video on the content side, the latter now available on compatible TVs (although it isn’t a member of the Alliance).

Initially seen as an upstart, that changed when word of the HDR10+ Alliance emerged. Comprised of three founder members – Samsung, Panasonic and 20th Century Fox – this changed the format’s status overnight, as it proved other big hardware players and a major Hollywood film studio were willing to back it.

Samsung and Panasonic account for a substantial chunk of the global TV marketplace, and 20th Century Fox – now part of Disney – has a huge library of content. And the fact that these three companies formed an alliance around it suggested they backed it against Dolby Vision, rather than alongside it.

That’s changed in 2019. Panasonic’s upcoming flagship GZ2000 OLED TV and 4K Blu-ray players support both HDR10+ and Dolby Vision, a trend we expect other TV manufacturers to follow (not Samsung, though). Such a move means a user’s 4K library is not restricted by a TV’s support for one HDR format over another.

Since that initial announcement Warner Bros. has become a content partner, and at CES 2019 we saw Blade Runner: The Final Cut and Wonder Woman running in HDR10+ on Panasonic’s TX-65GZ2000 OLED. Suffice to say the image looked spectacular. Joining them on the content side is Universal Pictures, so we could potentially expect titles such as Us and Fast & Furious presents: Hobbs and Shaw, to be made available in the format.

2019 has also seen a number of HDR10+ 4K Blu-rays has hit the home entertainment market. They include IMAX Enhanced titles such as A Beautiful Planet and Journey to the South Pacific, while Fox has released a HDR10+ 4K Blu-ray version of The Hate U Give in the US.

In Japan, Mary and the Witch’s Flower is in HDR10+ and in the UK  20th Century Fox’s Bad Times at the El Royale was the first followed by Bohemian Rhapsody, Alien and The Kid Who Would Be King. Since the studio has come under control of Disney it has released Alita: Battle Angel in both HDR10+ and Dolby Vision. We assume that was at the behest of producer James Cameron, but even so, that’s a promising development for the future of multi-HDR support.

Why does it HDR10+ exist?

It would be easy to feel annoyed at Samsung for muddying the HDR waters, but there are six solid reasons for its existence.

1) Better picture quality

It should make HDR picture quality better. The HDR10 industry standard provides a display with only a single luminance guide value from each HDR title that has to apply across the entire running time.

With HDR10+, content creators can use an extra layer of data to add updated luminance information wherever they want to – potentially scene by scene, or even frame by frame. Having this extra data to work with should help TVs deliver a more consistently impressive HDR picture. Cue HDR10+’s second raison d’etre…

2) HDR quality, for less

It can deliver a more uniform HDR experience across the TV world. The idea behind this is that cheaper, lower quality TVs usually don’t have enough picture processing power and know-how to handle HDR properly using the limited amount of information available with HDR10.

So adding dynamic extra data should have the most positive impact on the mid-range HDR enabled TVs, hopefully meaning you no longer have to spend a fortune on a TV to get a decent HDR experience.

3) It’s free!

HDR10+ is free. Even though it has chiefly been developed by Samsung, any brand can use it without having to pay Samsung a royalty. This is significant because the only other “dynamic” HDR format currently in play, Dolby Vision HDR, comes with a royalty fee attached.

In fact, Samsung’s refusal to pay Dolby its royalty is one of the key reasons it’s gone to the trouble of developing HDR10+.

4) And offers more freedom…

HDR10+ is apparently less prescriptive than Dolby Vision. By which I mean it leaves a little more freedom for different HDR displays to bring their own strengths and processes into play.

Both Samsung and Panasonic have previously argued that they trust their own processing and in-depth knowledge of their own screen capabilities to deliver better results than Dolby Vision’s “locked in” approach. Though Panasonic now supports Dolby Vision across its range of TVs so perhaps it’s changed its mind on that matter…

5) An open standard

HDR10+ is an open standard. This means that unlike Dolby Vision, it can constantly be evolved by anyone who uses it.

6) Easier to create with

HDR10+ is apparently easier to use in the mastering process. I have only anecdotal evidence of this from knowledgeable sources so far, to be clear.

But if true, it could play a big part in the format’s potential success, as content creators generally lean towards the simpler – and thus cheaper – of two solutions where a choice is available. That being said, the presence of Dolby Vision HDR is growing by the year.

Where can I find HDR10+ content?

Of course, the catch with HDR10+ is that it doesn’t just magically happen. TVs and 4K Blu-ray players have to carry the firmware to handle it, and content has to be made in it. So, what does the HDR10+ landscape look like?

Samsung’s TVs from 2017 have HDR10+ capabilities and all of its 2019 4K HDR TVs support the format. Oppo’s well-regarded UDP-203 and UDP-205 4K players have had their firmware updated for the format. Although they’ve both been discontinued, they’re still available if on the expensive side.

Panasonic did nail its HDR colours to the HDR10+ mast, but 2019 sees the Japanese brand’s TV lineup feature support for Dolby Vision. The flagship GZ2000 supports both HDR formats, becoming the first TV in the world to do so. The GZ1500, GZ950, GZ920, GX800 and GX700 TVs all have HDR10+ baked in and every TV from the GZ2000 down to the GX800 is compatible with Dolby Vision.

Philips, like Panasonic, supports a mixture of Dolby Vision and HDR10+ across its range of TVs. That leaves LG and Sony in the corner of Dolby Vision, with Samsung the only holdout on the Dolby Vision front.

For owners of older Panasonic TVs, the brand’s 2017 “4K Pro” TVs – essentially the EX750 LCD, and the EZ952 and EZ1002 OLED models – will, if not already, have had a firmware update. The majority of its 2018 4K lineup has also had a HDR10+ enabling firmware.

In terms of compatible 4K players, Panasonic’s UB9000, UB450 and UB150 support HDR10+. Samsung pulled out of the 4K player market so there won’t be any HDR10+ players from them.

HDR10+ on smartphone

While Dolby Vision has made an impression on smartphones and mobile devices, the same could not be said for HDR10+ until recently.

The launch of the Samsung S10 and S10+ made them the world’s first smartphones to feature HDR10+ certified screens for 4K HDR video.

You can expect a more appreciable sense of better brightness, more vivid colours and a better sense of contrast with the smartphones’ AMOLED screen. The S10+ can also record video content in HDR10+ as well.

Is HDR10+ any good?

It’s unlikely that Samsung would have bothered slaving over HDR10+ if it didn’t think adding dynamic metadata could introduce substantial extra picture quality advantages. But seeing is believing.

Fortunately, we’ve seen three separate HDR10+ vs normal HDR10 demonstrations. The first Samsung demonstration I saw had to be discounted on the grounds there was clearly too much variance in the core performance levels of the two displays. Fortunately, Panasonic had a seemingly more “authentic” demonstration in a blacked-out room, and Samsung allowed me to see a much more credible behind-the-scenes demonstration.

In both cases, the benefits of HDR10+’s extra metadata were clear. The main benefit comes in the amount of visible detail in the brightest parts of the HDR image; there’s much less “clipping” of subtle shades and tones than with vanilla HDR10.

This helps the picture look more detailed, and the impact of this detailing is further enhanced by a slight uplift during both demonstrations in the apparent brightness of the image’s most intense highlights.

Samsung’s head-to-head demonstration was done using a pair of its 2017 flagship Q9F models, and even on these high-end sets the HDR10+ difference was obvious. Even though, as discussed earlier, HDR10+ is expected to have the most impact on relatively affordable screens.

I saw no significant impact on colour tone reproduction during the Panasonic head-to-head, though, and on the Q9F the colour situation was hit and miss. Some tones did look richer and punchier under the influence of HDR10+, while others actually looked a touch more washed out.

However, this latter issue may be down to the Q9F’s edge lighting array struggling to control its light locally enough to prevent excessive light “bleaching” some tones slightly. We expect more recent TVs to show a better and higher level of performance.

Has the format war begun?

Dolby and the HDR10+ Alliance will tell you there’s no format war between their two dynamic HDR formats, since all HDR releases on disc and the vast majority of HDR streams will always provide an industry standard HDR10 “core”. As such, you’ll always get an HDR picture, no matter the advanced HDR format your TV supports.

For the majority of 2018 we were looking at a “soft” format war, in a similar way to Dolby Atmos and DTS:X surround sound formats; some films will only give their best picture quality on some TVs – depending on which advanced HDR format the content and the display are using.

That’s changed somewhat in 2019. Panasonic and Philips are trying to solve this issue by supporting all of the available HDR formats, including Dolby Vision and HDR10+. Samsung, on the other hand, is firmly in the HDR10+ camp, so it isn’t likely we can expect the company to adopt a “universal playback” policy any time soon.

Will HDR10+ grow?

HDR10+ didn’t get off to an auspicious start, but it’s picked up momentum and now feels like a genuine competitor to Dolby Vision – although Dolby continues to have a sizeable lead in terms of supported content and screens.

Some of those six advantages of HDR10+ are pretty persuasive, though, and with Dolby Vision support likely never showing up on the TVs of the world’s biggest (by far) TV brand, that has to be an issue, too. Content providers have been throwing their support behind the format, and we’ve started to see a trickle of dual HDR10+ and Dolby Vision 4K titles, with Robin Hood (2019), followed up by Alita: Battle Angel and Godzilla: King of the Monsters.

We’re optimistic we’ll see 4K Blu-rays have both advanced HDR formats onboard, and that other manufacturers will adopt the position of Panasonic and Philips and start supporting all types of HDR. In doing so, these TV manufacturers may be rewarded with persuasively handsome sales figures.
