Best answers:

• I use a Chromecast on my (non-smart) living room TV. With Plex media server on my PC, and the Plex app on my phone, I can stream media (movies, photos, music) from my PC to my TV over wifi).
  (It also means I can stream Netflix, BT Sports, etc. to my TV using my phone).
• any way of doing it for free,,i use plex media,
• read that wrong,so plex on to the moble ,but how do i get wifi to tv...
• You'd need to pay to buy something that enables wifi on the TV. A Chromecast is under Ј30 and will certainly work. You could look at a Roku as an alternative.
  Basically - you need a wifi device connected to the TV.
• Am I correct in saying that a Chomecast only sends certain media to your TV? e.g. netflix, youtube etc. or is it possible to actually display your PC desktop and basically use another TV as a wireless monitor? (if you have a long enough keyboard cable )
• which will require a usb connection,,
  i wonder if sky receiver will work ? as wi fi connector?
