To comprehend the error, one must first understand what Miracast requires. Unlike Bluetooth or traditional Wi-Fi, Miracast uses Wi-Fi Direct to create a dedicated, secure connection between a Windows 11 PC and an external display. The technology demands three non-negotiable components: a compatible wireless network adapter, a graphics driver that supports the Windows Display Driver Model (WDDM), and the proper NDIS (Network Driver Interface Specification) driver.
