Apple TV 4K launches with HDR to let users watch Netflix in stunning picture quality

Apple has launched Apple TV 4K at its iPhone X event.

It also has support for high dynamic range, a new television technology that makes images look much better, with more detail in the darkest and brightest areas of pictures.

In demos, image quality looks fantastic, but there's one big catch.

You have to have a 4K TV with HDR support in order to replicate that.

Apple is making 4K available for the same price as HD on iTunes. If you've bought one of those films already in HD, you'll get them in 4K HDR for free.

Other streaming providers like Netflix and Amazon will be bringing their 4K HDR stuff to Apple TV too.

Apple TV 4K is available for $179 and you can order it from 15 September.

It will start shipping a week later, on 22 September.
