Where else can you stream 4K video?

There are a few services that offer 4k:

Netflix was one of the first video-on-demand services to announce it would be supporting 4K streaming, which went live in the UK.

Amazon also offers 4K content through its Prime Video streaming service.

You can watch 4K video via the Amazon Prime Video app on compatible TVs and the latest 4K Fire TV box. You can see a full list of Amazon Prime Video devices here - note this is a list of compatible devices with the movie streaming app and not necessarily 4K content.

UltraFlix is a another 4K streaming network from NanoTech, which has apps available on Samsung, Sony, Vizio, Sharp and Hisense TVs.

Sony has launched its own 4K Video On Demand service in the form of Video Unlimited 4K, but is only available in the US.

What about 4K TV channels

BT became the first broadcaster to launch an Ultra HD channel to the UK, with BT Sport Ultra HD in August 2015. 

Sky is the "UK's most comprehensive Ultra High Definition service" through its Sky Q platform launched it's ULRA HD service in August 2016.

For many, getting a fast broadband connection to support 4K streaming (realistically at the very least 30 Mbps) isn't fully possible right now.

Therefore a better way to get 4K content into the home would be on a Blu-ray disc format.

Ultra HD Blu-ray that can handle resolutions up to 3840 x 2160 are available but slow to take off.
