Screen mirroring problems with Samsung Smart TV. Won't screen mirror phone(s), iPad or windows 8.1 PC. Getting very frustrated. Have downloaded Samsung Smart View 2.0. Doesn't connect to TV from PC - says TV not ready. BT wireless hub connecting to both. Doesn't connect to iPad (also downloaded Samsung Smart View 2.0) but says incorrect pin, although it never asked for a pin to be entered. It does however recognise and display the TV name on iPad, and both Windows and Android phones. None will connect. Need further advice. Thanks
