Miracast is a wireless communications standard created by the Wi-Fi Alliance which is designed to transmit video and sound from devices (such as laptops or smartphones) to display receivers (such as TVs, monitors, or projectors). It uses Wi-Fi Direct to create an ad hoc encrypted wireless connection and can roughly be described as "HDMI over Wi-Fi", replacing cables in favor of wireless. Miracast is utilised in many devices and is used or branded under various names by different manufacturers, including Smart View (by Samsung), SmartShare (by LG), screen mirroring (by Sony), Cast (in Windows 11) and Connect (in Windows 10), wireless display and screen casting.
A related enterprise protocol named Miracast over Infrastructure (MS-MICE) functions using a central local area network instead, and is supported in Microsoft Windows.
