New on Plex; I have set everything up: media server, libraries, & player.

Everything works perfectly; Plex is wonderful.
My question is: Do need to keep my Windows PC with media server running or can I shut down and view content from only my Roku 3 on smart tv?
Thanks for any help

You need to keep your media server running as that’s what is actually doing the streaming to your Roku.

Thank you for answering my question.
