Chromecast is a media streaming device that plugs into the HDMI port on your TV. Simply use your mobile device and the TV that you already own to cast your favourite TV shows, movies, music, sport, games and more. Chromecast works with iPhone®, iPad®, Android phone and tablet, Mac® and Windows® laptop, and Chromebook. It currently costs £30 and is very easy to set up. It works best with newer android tablets and phones (running v4.4.2 or above)
On older tablets, you may need to optimise the memory and running apps in order for it to work.
