WiDi (Wireless Display) is a screencast technology from Intel and allows streaming the screen content of a personal computer or notebook to a TV, projector or via HDMI interface to other consumer electronics displays.
WiDi requires an Intel central processing unit( CPU), a WiDi-enabled WLAN module, and an operating system running Windows 7 or later. Screencasting achieves video resolutions in High Definition Television( HDTV) with 1,920 x 1,080pixels in the standard 1,080p. Copyrighted Blu-Ray discs or DVDs can also be streamed with WiDi.
WiDi was developed by Intel, but has since been abandoned and replaced by the WiFi Alliance's open screencast standard Miracast. Intel's WiDi drivers have enabled transmission to Miracast receivers since October 2012.
