In the history of wireless display technology evolution, Intel’s
WiDi technology once held a pivotal position. Although it has gradually been replaced by newer standards, understanding WiDi’s technical features and historical value is of great significance for grasping the progression of wireless screen mirroring technologies.
WiDi (Wireless Display) is a wireless display technology launched by Intel, first released in 2010. It was designed to enable users to transmit laptop screen content to TVs or projectors without the need for cables.
WiDi establishes direct device-to-device connections based on Wi-Fi Direct technology, and realizes wireless transmission of video signals through specific encoding and decoding algorithms. This technology requires both the sender and receiver to support corresponding hardware specifications.
