3. Check TV for Miracast Support

If you know the exact make and model of your television, you can check online if it supports Miracast.

Otherwise, you can check in the menus of the television itself to see if Miracast or casting is listed as an option.

Check Online

The WiFi Alliance, the group that controls and sets the standard for Miracast support, maintains a list of Smart Televisions and other devices that support Miracast.
