I am a newbie to plex. Just want to know if I could use my Egreat media server which is as my client as I do not have a Smart TV, or is there another way to use Plex MS with a non smart TV.
Thanks

I am a newbie to plex. Just want to know if I could use my Egreat media server which is connected to my TV (on the same LAN as PMS)as my client as I do not have a Smart TV, or is there another way to use Plex MS with a non smart TV.
Thanks
