Netflix asks for around 25Mbps for a 4K video stream, though, and HDR is around a 10 per cent overhead on top of that. In apps that support it, and as long as your home internet connection is fast enough, you can stream 4K HDR video. The Chromecast Ultra, though, improves on the Chromecasts it replaces complements by adding in native support for 4K television screens and high dynamic range (HDR) video. The Chromecast has always been unique in that your phone does all the work - browsing content in your familiar apps and picking a show, and ‘casting’ it to Chromecast. Your grandparents could set one up, as long as they can read instructions on a phone and on a TV screen.

You plug it into your TV’s HDMI port, you power it over USB either from your TV or from an included wall plug, and you run everything from your Android or iOS phone. The $99 Google Chromecast Ultra is the third and latest iteration of the Chromecast wireless video streaming dongle. Is its $99 price worthwhile over the existing $59 Chromecast, though? Using your phone as a remote control, it can wirelessly stream the best quality video possible from Netflix, YouTube, Stan and a host of other Google Cast apps. But for that price, it supports 4K video, and high dynamic range video. Google’s latest Chromecast dongle comes in at twice the cost of its predecessor.
