WiDi

Wireless Display (WiDi) is technology developed by Intel that enables users to stream music, movies, photos, videos and apps without cables from a compatible computer to a compatible HDTV or through the use of an adapter with other HDTVs or computer 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.

For other uses, see WiDi (disambiguation).
This article is about the discontinued protocol by Intel. It is not to be confused with Wi-Fi Direct, which is sometimes shortened as 'WiDi'.

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.[4][5]

WiDi development was discontinued in 2015 in favor of Miracast,[6] a standard developed by the Wi-Fi Alliance and natively supported by Windows 8.1 and later.[7] In Microsoft's Windows 10 operating system, the built-in Wireless Display is called Project, which can be used to mirror the device's display to a TV[8] if it supports Miracast.

Miracast
Main article: Miracast

The Miracast standard is supported in Intel Wireless Display versions 3.5 through 6.0,[18] when it was discontinued.[19] After this development, Intel recommended that business users utilize Intel Unite as a platform for collaboration.[19] Miracast was included in Android 4.2 smart phones through Android 7, and on Windows 8.1 and 10. It can stream on TVs, projectors, and media players.[20]
