I own a JVC old european TV and a fire stick tv lite. I used to have a TV in my room and connect it to my desktp PC with an HDMI cable but I removed the telly in order to have more space.
In my living room I have this JVC TV I can use, but I doubt there’s much I can do on it.
One solution would be to buy a laptop with HDMI port, but that’s expensive for me right now. My old laptop doesn’t have any port.
What would be the best solution to watch movies and tv shows on the TV?
the tv must support jellyfin/plex though right?
Yes.
If you cannot install Plex or Jellyfin on the TV, a streaming device can be added.
You can also build your own streaming device with Kodi. An old laptop would work if you don’t have the means otherwise.
Use a firestick or Roku on the TV. I have a brand new TV and still don’t use the smart features on it because they’re generally not very good compared to one of these streaming sticks.
