PC Does Not Support Miracast on Windows 10

The Windows Display Driver Model (WDDM) is a crucial component of the Windows operating system, responsible for managing graphics and display drivers. WDDM was introduced in Windows Vista and has since become the standard driver architecture for video card drivers running Microsoft Windows versions starting from Windows Vista.

One of the key features of WDDM is its ability to support legacy Direct3D applications. This is achieved through the implementation of device driver interfaces for the Direct3D 9Ex runtime, which allows for the smooth operation of older graphics-intensive programs. Additionally, WDDM provides support for new DXGI interfaces required for basic device management and creation.

WDDM also plays a critical role in rendering the desktop and applications using Desktop Window Manager, a compositing window manager that runs on top of Direct3D. This ensures that graphics are displayed accurately and efficiently.

It's worth noting that with the removal of XDDM from Windows 8, WDDM became the only option for display drivers. In earlier versions of Windows, such as Vista and Windows 7, display drivers could choose to adhere to either WDDM or XDDM.

WDDM is aimed at enabling better performance graphics, new graphics functionality, and stability. It has replaced the previous Windows 2000 and Windows XP display driver model XDDM/XPDM.

In summary, WDDM is a crucial component of the Windows operating system that provides a platform for video card drivers to run smoothly and efficiently. Its ability to support legacy Direct3D applications and new DXGI interfaces makes it an essential part of the Windows ecosystem.
