Amazon just announced another perk for Prime subscribers: 4K video streaming. That's right, Ultra HD content is now available via monthly membership through the Instant Video app or on compatible smart TVs. For now, the selection is a bit limited, but you can expect to enjoy Amazon Originals, BBC's Orphan Black and a smattering of titles from Sony Pictures Entertainment in all of their 4K glory. Better video quality doesn't come with an extra fee either, as the content will be lumped in with the rest of those Prime perks. Amazon's a little tardy with the rollout, but hey, we can't complain too much as it's here in time to break in that shiny new TV Santa will deliver in a few weeks.
