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?
You wouldn’t want a laptop for that. A cheap “mini PC” would be the more appropriate choice. Shop around, you can probably find a second-hand or refurbished one with an hdmi port for under $100.
