What cable do I need to connect a laptop to a TV?
An HDMI cable, if the laptop has an HDMI socket. If it only has USB-C, you need a USB-C to HDMI adapter or cable, and the USB-C socket must support video (often marked with a DisplayPort or Thunderbolt symbol).

How to connect it
- Connect the laptop to the TV's HDMI socket.
- Switch the TV to that input.
- On Windows press Windows key and P to choose Duplicate or Extend; on a Mac, use Displays in System Settings.
Worth knowing
- Older laptops with VGA sockets need a VGA to HDMI converter, and send sound separately.
