If you treated yourself to a 4K television in the Black Friday sales, you’re going to love Amazon’s latest Instant Video update, because the retail giant is now showing movies and TV shows in Ultra HD. Not only can you buy and rent 4K content, but you’ll also be able to stream it as part of your Prime subscription — but only if you live in the U.S.

A ton of 4K content is already available through Amazon, including movies such as Captain Phillips, American Hustle, Elysium, and After Earth — which are available to buy and rent. If you have Prime, you’ll be able to stream shows like Alpha House, Transparent, and Gortimer Gibbon’s Life on Normal Street in 4K at no extra cost.

“We want to deliver the best entertainment experience, and offering Ultra HD movies and TV shows raises the bar on quality and innovation that customers have come to expect from Amazon,” said Michael Paull, Vice President of Digital Video at Amazon. “We’re also excited that Ultra HD is the latest benefit of the Amazon Prime membership, giving members instant access to great movies and TV shows in a premium picture resolution at no additional cost.”

If you don’t already have an Ultra HD TV and you’re not sure whether they’re worth it yet, check out Amazon’s guide to 4K, where you can learn about the benefits of 4K technology, and how much it costs. You’ll also find Amazon’s pick of the best 4K TVs there from Samsung, Sony, and LG.
