Amazon launches 4K Fire TV streaming box

The new Amazon Fire TV box claims to be more powerful and faster than its predecessor, while also promising better wi-fi performance.

There's also now a microSD card slot for adding up to 128GB of storage to the 8GB storage inside, plus support for the new HEVC codec to improve 4K and 1080p HD video performance, and an HDMI 2.0 connection. Amazon has however removed the digital audio optical output.

But the headline-grabbing news is that support for 4K Ultra HD video, with Amazon boasting that its new Fire TV box will deliver "more 4K Ultra HD movies than any other streaming player".

The existing Fire TV majors on Amazon's own content, so it makes sense for the new box to support the 4K video on Amazon Instant Video. Amazon has also adopted HDR video on some of its shows, showing the company's eagerness to adopt the latest video technology.
