Can I use this Samsung TV to play films or videos on a laptop so that you can connect it to the TV with a cable and then see it on the TV? How exactly does it work?
Here is my TV set
Yes, it works with an HDMI cable.
Both your laptop and a television should have a connection for this.
You plug the cable into both devices and then switch the source on the television to HDMI.
Either via an HDMI cable or, if your TV is internet capable, you can do this via the WLAN.
You can either use an HDMI cable or a Chomecast.
The Chromecast has the advantage that it works via Wi-Fi.
