Call it an end-of-year resolution for higher resolution: Amazon says its long-promised 4K video streaming service will arrive before the end of the year.

Amazon, along with a few other companies, promised it would offer the next-generation video for compatible Ultra HD TVs back at CES in January. But even as Ultra HD TV prices have dropped to as low as $1,000, streaming 4K content has been hard to come by. Netflix was the first to arrive on Ultra HD TVs in the spring, yet it now has only about a dozen movies and TV shows available for subscribers. And recently the company began charging an extra $4 on top of the monthly $8 subscription for the 4K service.

Amazon says that if you subscribe to its $99-per-year Prime service, streaming in 4K won’t cost you any more. But it may require an update to the built-in Amazon Instant Video app on your Ultra HD TV.

“We’re confident that offering Ultra HD content, whether it’s a TV series or a film, will help create the ultimate viewing experience,” said Michael Paull, Amazon’s vice president of digital video, in a statement.

Here’s one kind of ultimate viewing experience: They’ve got Lady Gaga in 4K. Amazon says its collection will include the “Lady Gaga: Cheek To Cheek” concert, as well as Amazon-made shows “Transparent,” “Alpha House” and “Mozart in the Jungle.” Hopefully they’ll throw some movies into that collection soon, too.
