Our telly is a Sony Bravia about 5/6 years old. Don’t believe it is a “Smart” TV as had to get a Google Chromecast plugged into it before we could send wirelessly from computer. Was the only way to get all the All-4 programming. Understand that more modern models will receive data directly without need for Chromecast or Firestick. TBH, the whole range of what it is possible for TVs to do and what their makers allow you to do is utterly brain-boggling.
