We used to have a plasma, and we bought a Chromecast for it. You stick it in an HDMI port on your TV, open the streaming service on your smartphone app, and select what you want to watch. Once it starts to play on your phone, tap the Chromecast icon in the top corner, and it goes to your TV. It was very effective. Then we bought a smart TV and didn't need that anymore.
Thank you, will have to look at that as I was thinking of moving the plasma in to the kids play area as we have newer tvs etc now
