Check that the PC and Smart TV are on the same network. This is the number one requirement for both devices to be able to see each other over your home network, whether via Wi-Fi or an Ethernet cable.
Check that your TV is compatible with Miracast or that you have an adapter.Many modern smart TVs feature Screen Mirroring, Connect, or Miracast compatibility. If your TV doesn't support it, You can use a Miracast dongle/key connected to the TV's HDMI.
Windows 10 and Windows 11 include native support for wireless projection.On these systems, you can use the shortcuts and projection menus without installing anything additional in most cases.
Optional: WiGig basesSome devices support very high-speed wireless connectivity via a WiGig base. If your PC supports WiGig, you'll see its control in Settings > Network & Internet > Airplane mode, and you can link it with monitors or projectors connected to that base.
If you work with different resolutions between PC and TV, the quality may not be optimal the first time. You can always adjust resolution and scale in Windows and tap picture options (brightness/contrast) on TV until you find the ideal spot.
