Many of you have devices that probably already support Miracast. You can check online for the list of supported devices which includes a short list of Intel video drivers and Android devices. The latest Microsoft Surface devices (version 2) support it out of the box with Windows 8.1 and the included drivers. However, the original Microsoft Surface Pro does NOT support it – even with the Windows 8.1 update installed. But, with the right hardware and after applying an unsupported fix, it works beautifully.
