WiDi

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.

The Miracast standard is supported in Intel Wireless Display versions 3.5 through 6.0, when it was discontinued. After this development, Intel recommended that business users utilize Intel Unite as a platform for collaboration. Miracast was included in Android 4.2 smart phones and onwards and on Windows 8.1 and 10. It can stream on TVs, projectors, and media players.
