Windows Display Driver Model (WDDM) 1.3 and later drivers can optionally support wireless (Miracast) displays. This documentation is therefore deprecated and Microsoft might remove support for custom Miracast stacks in a future version of Windows. As of Windows 10, the OS ships with a built-in Miracast stack that can work on any GPU and it is no longer recommended that drivers implement a custom Miracast stack. This document describes how drivers can implement a custom Miracast stack in Windows 8.1.
