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[1] and can roughly be described as "HDMI over Wi-Fi", replacing cables in favor of wireless.[2] Miracast is utilised in many devices and is used or branded under various names by different manufacturers, including Smart View (by Samsung),[3][4]SmartShare (by LG), screen mirroring (by Sony), Cast (in Windows 11) and Connect (in Windows 10), wireless display and screen casting.[5][6][7]
A related enterprise protocol named Miracast over Infrastructure (MS-MICE) functions using a central local area network instead, and is supported in Microsoft Windows.[8]
