ROKU4/ultra review and tutorial

The ROKU4 is a very powerful streaming device. The OS is very simple and the response is very quick. Watching 4K is excellent, there is no delay or tearing in the image. I hope it is available in the UK for viewers to enjoy. No doubt there will be a few other streaming devices available but at present Amazon Fire TV, Apple TV and many other streaming are not as capable as this unit at streaming 4K@60fps over HDMI2.0. Watch the ROKU4 review for more details. I have added more into the video to show Serviio and Windows Media Server streaming to a ROKU4 using DLNA
