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?
If the TV has an ethernet port you could connect it to your LAN then stream from your PC with plex or jellyfin.
Or you could just get a really long HDMI cable to reach your PC (I think you can go up to 20 metres).
the tv must support jellyfin/plex though right?
Yes.
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.
