1. Turn on your TV or projector. If you’re using a Miracast dongle or adapter, make sure it’s plugged in to the display.
2. On your PC, make sure Wi-Fi is turned on.
3. On right side of the taskbar, select the Network icon > Cast > pick your display or adapter.
4. Follow any additional instructions on the screen. Otherwise, you’re done.
