How to change HDMI output to input on laptop

Your laptop has many ports and have you ever wondered what they’re all used for? One of the ports you’ll find is the HDMI port that you can use to watch movies on your TV instead of your laptop screen.

You can use external adapters that can take in HDMI input from an external device which can then project it to another device using a USB port or another port.
