Are there smart TV's that come with a program that you can download the NHL app or whatever, to then be able to log into your account and watch hockey on say a 55" tv? Is this like Roku, or something? What are the different ones that support something like that? I am old now, I can see.
You can buy an Apple TV device (looks like an enlarged hockey puck; no iPhone or iPad required) and connect it to your TV. Or, you can connect a regular computer to your TV. Both works for me for watching NHL.tv on my large TV set.
