LPT: If you live alone and have multiple TVs in your house, you can put a small tablet in a room and watch tv in there with a decent sized screen by using a casting app

To add to this, you don’t even have to have a smart TV. Just plug a computer into your TV and use a casting browser plugin (like cast to tv on chrome) to stream from anywhere connected to your WiFi, although an extremely slow computer may result in lag.
