Wireless Display (WiDi) is technology developed by Intel that enables users to stream music, movies, photos, videos and apps without wires from a compatible computer to a compatible HDTV or through the use of an adapter with other HDTVs or monitors. Intel WiDi supports HD 1080p video quality, 5. 1 surround sound, and low latency for interacting with applications sent to the TV from a PC. Using the Intel WiDi Widget, users can perform different functions simultaneously on their PC and TV such as checking email on the PC while streaming a movie to the TV from the same device. WiDi was discontinued in 2015 in favour of Miracast, a standard developed by the Wi-Fi Alliance and natively supported by Windows 8. 1 and later. On the latest Windows 10 by Microsoft, the built-in Wireless Display is also called Project, which can be used to mirror Win 10 to TV for those Miracast Supported devices.
