That means HDR video looks more like real life, when compared with HD. You'll also need a TV that supports HDR to see any benefit.
Several of today's top video services already support HDR video, even though the technology hasn't made its way into all consumers' homes. Amazon, meanwhile, rolled out HDR support back in 2015. Now, Google has announced that the Play Movies & TV service will offer a selection of content in HDR on supported devices. In the post, Google said that it the HDR support on Play Movies & TV will initially roll out to the United States and Canada, where it will be accessible on all Google-connected devices that come with HDR support. Google says there will only be around a dozen movies available at first, but it expects that number to grow.
The problem thus far for the nascent format has been the slow trickle of content that has yet to yield a significant torrent for thirsty HDR TV owners.
Google did not offer an estimate as to when HDR support would reach its other global markets, beyond telling us it would be in the "coming months". This includes TVs with Google Cast built in, including some sets from Vizio, Sony, Toshiba, Philips, and others, as well as Google's own Chromecast Ultra.
