If you’re working from home and in need of an extra display to manage the workload then your TV just might be the perfect solution. You can connect your TV as a second display on Windows 10 using the WiFi Adapter of your PC. It can either be pre-installed on the motherboard of your rig or built-in on your laptop by default.

The process or the menu navigation to activate the screen mirroring feature is variable as it is based on different manufacturers and their interface, but you can always go through the instruction manual or the OEM's website to learn more.
