WiDi (Wireless Display) is a wireless display technology developed by Intel. It enables users to wirelessly stream music, movies, photos, videos and apps from a WiDi enabled computer to another compatible HDTV or through the use of a WiDi adapter with other non compatible HDTVs. Intel WiDi supports HD 1080p video quality, 5.1 surround sound, and low latency for interacting with applications that are sent to the TV from a PC.
Miracast standard was supported in Intel WiDi version 3.5. Visonicom RealCast PTV WiFi display adapters support WiDi 3.5 or greater.
