Tesco
It's mis-sold in Tesco with little explanation.
I'll stick to using a hidden £2 HMDI cable spliced to 2 x screened Cat5e running to Media PC in another room. It also has IR remote sensor at TV over a Cat 5e. The USB hub at TV simply uses 2 x max length USB cables and a USB repeater in the middle.
Also use laptops, phones, tablets with TV.
The Chromecast needs a Laptop/Tablet anyway.
