HDR10+ – everything you need to know


As the AV world tries to get a handle on Dolby Vision and HDR10, the imminent arrival of yet another HDR (High Dynamic Range) format – one that’s designed to beat Dolby Vision at its own game – has been largely overlooked.

This format is HDR10+ and it’s the creation of Samsung, which sells more TVs around the world than any other brand.

But is this new HDR format a cause for celebration or consternation? On one hand, it muddies the already-confusing TV-spec waters and is taking an age to come to fruition where content is concerned. But, on the other, HDR10+ looks and sounds great and seems to be getting all the support it needs.

What is HDR10+?

Like Dolby Vision, HDR10+ is all about adding dynamic metadata to the HDR signal.

Standard HDR10 uses static metadata, which means the boundaries of brightness are set at the start of a film or show and don’t budge for the duration.

These boundaries have to be broad enough to display every scene of the film – essentially, the TV’s 1.07 billion colours are spread evenly across that entire brightness spectrum, which means that if a scene contains only bright or only dark elements, only a portion of those colours are available for it. This can result in dark scenes looking a bit dim and bright scenes losing detail.

With dynamic metadata, those brightness boundaries can be set and changed on a frame-by-frame basis, so the full colour range can be deployed even in scenes that contain only dark or only light elements. The result, in theory, is subtler gradients and therefore more detail.

We’ve already seen this in action with Dolby Vision. The Power Rangers 4K Blu-ray is noticeably improved in Dolby Vision when compared to HDR10, particularly in regard to bright lights in otherwise dark scenes and subtle details in bright areas of an image. In short, it’s a more exciting, enticing and nuanced picture.

How is HDR10+ different to Dolby Vision?

At their core, HDR10+ and Dolby Vision are similar – they both use dynamic metadata to tweak a TV’s performance to get the most out of every frame – but there are key differences.

For a start, while TV manufacturers and studios have to pay Dolby to license Dolby Vision, and therefore have little control over its development and implementation, HDR10+ is a royalty-free, open format that any company, including Samsung’s rivals, can tweak and deploy as it sees fit. It's not entirely free; there is a “nominal” annual administrative fee for the companies wanting to use it.

This should make it appealing to those who don’t want to pay a high fees or hand over control of the process in order to introduce support for dynamic metadata.

Similarly, Samsung claims because the TV manufacturers have more control when it comes to HDR10+, they can more effectively tailor it for different models in their ranges.

According to Samsung, mid-range TVs will benefit most from the addition of HDR10+ because the format will allow them to adapt the image to models with a more limited brightness spectrum to suit their abilities.

On the other hand, as a layer of dynamic metadata for HDR10, HDR10+ carries over the limitation to 10-bit colour depth. Dolby Vision goes up to 12-bits, making it capable of reproducing billions more colours.

With 12-bit TVs still the stuff of fantasy, this isn’t a big deal yet - but when they do finally become reality this could be a big differentiator. Of course, there’s every chance that new, open formats (HDR12 and HDR12+, perhaps?) will also arrive at that point.

Is HDR10+ actually any good?

HDR10+ is currently limited to Amazon Prime Video on select Samsung TVs and a handful of Ultra Blu-ray discs in the USA, but we’ve been unable to conduct our own tests of the format. We have, however, seen the tech as presented to us by Samsung and Panasonic. While demos such as this can’t be relied upon to draw firm conclusions, they’re certainly enough to get us excited.

Next to a standard HDR10 image, HDR10+ seems punchier, more dynamic and adds more depth to the picture - but, importantly, doesn’t alter the fundamental character of the picture. The whitest elements and brightest colours look brighter, while the blackest areas become more pronounced. But nothing becomes overblown or unrealistic.

In fact, in many areas there’s greater nuance and detail – bright skies that are over-saturated in HDR10 reveal subtle gradations of colour and thin, light-grey clouds in HDR10+.

In short, the result isn’t just more dynamism, it’s a more detailed, more solid and more three-dimensional image that draws you in more effectively.

These are exactly the type of improvements we expect to come from the introduction of dynamic metadata, and the fact HDR10+ offers improvements over HDR10 isn’t much of a surprise.

The more interesting question is how it compares to Dolby Vision. Right now there’s no way for us to test that, but 2019 will certainly be the year we're able to find out...

Which devices support HDR10+?

Ever since CES 2018, we've had confirmation of growing HDR10+ device support and what content will be available in the future.


As you might expect from the format founder, select Samsung 2018 TVs, including its Premium UHD and QLED TVs, currently support the format. Its forthcoming 2019 4K sets will ship with HDR10+ too. If the format survives, it's safe to say compatibility will be standard across Samsung's future TVs.

As for legacy models, all of Samsung’s 2017 HDR TVs have a picture-processing engine that supports HDR10+ too, but a firmware update will be needed to activate the feature. 

Samsung's 2017 M9500, M8500 and M7500 Ultra HD Blu-ray players were due a HDR10+ update last year, but as far as we know it hasn't arrived yet. We're checking.

To the smaller screen, and Samsung has also included HDR10+ compatibility in its Galaxy S10 and S10+ smartphones. Not only will you be able to watch eye-popping content on the go, but the phones are also able to record video in HDR10+.


Along with Samsung and 20th Century Fox, Panasonic is one of the three founding members of the HDR10+ Alliance, so it's not surprising its two 2018 OLED ranges and most of its 4K TV line-up support HDR10+. 

Its 2019 flagship, the GZ2000 4K OLED, is the first TV to support both HDR10+ and Dolby Vision, covering all HDR bases (with additional support for HDR10 and HLG). We were told HDR10+ would be the default should the TV be fed a signal that also supports Vision, but the user would have the ability to choose.

Three of Panasonic's five 2018 4K Blu-ray players, the DP-UB9000, DP-UB820 and DP-UB420 support for HDR10+ (with the former two also supporting Dolby Vision). Again, its 2019 players, the DP-UB150 and DP-UB450, will launch with support.

Panasonic's higher-end 2017 TVs (the EZ1002, EZ952, and EX750) are all due a firmware upgrade to add HDR10+ too.


Philips is the latest TV brand to support HDR10+, adopting the format instead of Dolby Vision for its 2018 TVs. The Philips 55OLED803, 65OLED803 and 55OLED903 will play HDR10+ content. 

We expect Philips to announce its 2019 models with HDR10+ support in the coming weeks too, so watch this space.


Pioneer's latest UDP-LX800 and UDP-LX500 4K disc-spinners will support HDR10+ following a firmware update in spring 2019.

Owners of the Oppo UDP-203 and UDP-205 will be happy to know that these players have recently received a HDR10+ firmware update.

Will more manufacturers adopt HDR10+?

We'd have expected the fee-free nature of HDR10+ to make it a no-brainer for many manufacturers, but would LG (Dolby Vision's biggest TV supporter) even consider supporting a format created by its arch-rivals? Despite LG being the champion of broad HDR format support so far, we think it seems very unlikely.

So far, Sony also seems committed to only supporting Dolby Vision.

Just before Christmas, Samsung announced an expansion of the HDR10+ ecosystem to 45 partners, the new ones of which include Hisense, TCL and Qualcomm, so we should expect more device support announcements soon.

While it would be easier if there was just one HDR format, there’s nothing stopping TV manufacturers and content producers from supporting both. Those that do (such as Panasonic in the TV arena) will almost certainly have an advantage unless one format manages to kill the other. Game on.

So what can you watch?

20th Century Fox’s early involvement importantly put a content producer on the map, with the studio set to reveal its first slate of HDR10+ titles any week now.

In January 2018, Warner Bros. Home Entertainment also confirmed its support for the format and, according to Samsung at the end of last year, Warner plans to have over 100 titles available for digital distribution in HDR10+ by early this year.

While Amazon isn’t yet part of the HDR10+ Alliance, the format is already accessible on Amazon Prime Video for a select few TV owners in the USA and UK as well as owners of the Amazon Fire TV Stick 4K. As the format isn't flagged by the device or TV app, however, there's little means of verification that what you're watching is actually in HDR10+ - at the moment, anyway.

Samsung says that Rakuten TV, a European online streaming service and also a HDR10+ partner, will begin offering HDR10+ content in the first half of this year, too.

Despite growing industry support, recently confirmed compatibility for more hardware, and the firming up of certification for devices (which will be performed by a third-party testing centre, with certified products naturally bearing the new HDR10+ logo), we still await a first proper wave of accessible HDR10+ releases.

Before Christmas, nature documentaries A Beautiful Planet and Journey to the South Pacific were released in HDR10+ on Ultra HD Blu-ray in the USA. They also happen to be the first IMAX Enhanced discs available.

Bohemian Rhapsody, Bad Times at the El Royale, and The Hate U Give are just some of the titles set to have HDR10+ in the disc release.
