Good news this week for owners of the Chromecast with Google TV, plus a handful of new Roku streaming sticks: These have now been certified to work with HDR10+ video.
As you might well guess, HDR10+ is an upgrade to HDR10, which is itself a form of HDR video, which stands for High Dynamic Range.

This video offers more vivid colors, deeper blacks and brighter whites thanks to it containing dynamic metadata. Whereas regular HDR boosts the brightness and dark levels of a TV screen when the content starts, then sticks to those levels, the metadata of HDR10+ video adjusts the brightness and darkness on the fly.
This means the brightness of the screen adjusts constantly while you watch a video, helping to improve your view of every frame. If this technology sounds familiar, then you might already know that Dolby Vision also does this.
Thanks to the new certification, HDR10+ is coming to the Chromecast with Google TV, as well as the new Roku Express 4K+, Roku Express 4K, and the Roku Ultra. The Paramount Plus streaming app is also getting the upgrade to HDR10+, when installed on compatible televisions.
Matt Frost, director of product management at Google, said: "We envision HDR10+ being a key enabler for Chromecast with Google TV plus other platforms going forth and we look forward to helping our various partners across the industry achieve a great HDR experience."
The Roku Express 4K gains HDR10+ support Roku
There isn't a huge amount of HD1R10+ content available right now, however, and Dolby Vision is the more popular video format to include the brightness metadata. But that could change with more devices being certified, and HDR10+ content is already available on Amazon Prime Video, Google Play and YouTube.
All of that said, you can only access HDR10+ content through a compatible TV (and streaming device), so you will want to check the specifications of your TV, or the one you intend to buy, to see if it supports HDR10+. These TVs include some models from Panasonic and Samsung, with the latter being the primary company behind HDR10+. For that reason, Samsung TVs do not support Dolby Vision.
It's a slightly messy situation for now, and we hope in the near future all models of TV support both the HDR10+ and Dolby Vision formats.
