Both the Google Chromecast with Google TV and three recently launched Roku Express + devices were certified for HDR10 + this week. That is a standard for high dynamic range, which mainly competes with Dolby Vision.
Chromecast with Google TV and HDR10 +
Now that the Chromecast with Google TV, as well as those Roku devices, have the necessary support, owners of the device can watch content in HDR10 +. You still need a television that can process the signal. Think of a television from Panasonic or Samsung, among others. Samsung is the driving force behind the HDR standard.
The video streaming service you use must also offer support. These include Amazon Prime Video, YouTube and Google Films. In addition, the American streaming service Paramount + also offers content in this standard. Amazon Prime Video lets you include The Marvelous Mrs. Watch Maisel and The Grand Tour in HDR10 +.
HDR10 +, like Dolby Vision, has dynamic metadata. This means that the standard does not simply activate the HDR mode on your TV when you start a movie or series that supports HDR10 +. Because the metadata is dynamic, the settings can be adjusted while viewing for the best possible result. If you’d like to read more about the announcement, you will find the pdf file here.
