Hello, thank you for reaching out to Microsoft Q&A.
First, turn on your TV.
Then, go to the TV’s display settings and turn on Display Mirroring (or the equivalent option for screen mirroring). This will allow the TV to wirelessly mirror your PC’s display.
Once that’s enabled:
- On your PC, press Windows logo key + K on your keyboard.
- Under the list of available devices, select your TV.
Your laptop screen will now be mirrored on your TV.
Note -
This only works on laptops that support Miracast; some laptops may not have Miracast support. You can check this via Command Prompt by typing netsh WLAN show drivers, then looking for whether Wireless Display Supported is listed.
