Hello -- I was watching a video on youtube and the "play on tv" option listed my roku ultra as a casting device --- how to I do that? is there a option in the youtube (roku) channel to received the cast or does the roku itself have an option for this?
This is casting functionality built into the YT app for all platforms based on a protocol called DIAL.
Simply choose your Roku in the YT app casting list and (assuming "1 touch play" is enabled) your TV should switch to the Roku input, open the YT app, and start playing the content you selected (which you control via your tablet/phone/etc...).
You might have a box appear in the TV screen asking for permission for the connection. Just say yes and away you go.
