  1. Is your Windows 10 from a upgrade of Windows 7 or other earlier version? If so, your Windows 10 may not have the built-in Miracast support. In this case, you can make use of a Miracast adapter, like Microsoft wireless display adapter.
  2. Is your Windows 10 is of a clean-installed version? If so, it should support Miracast then. Then why does this error still happen? Probably your display or Wi-Fi drivers are to blame. You can solve the problem through updating your drivers.
