Miracast

Miracast is a wireless display standard developed by the Wi-Fi Alliance. It allows audio and video content to stream from one device to another without cables or an internet connection. It uses Wi-Fi Direct to establish a peer-to-peer connection between the source and display device, allowing real-time video and audio transmission.

Miracast allows for easy sharing of media, presentations, and other content between devices and mirroring a device's screen to a display; this feature is often called screen mirroring.

Miracast is an alternative to other wireless display technologies such as Chromecast and Airplay; however, it's less popular than the others, and its adoption is limited. Also, it's not compatible with all devices, so checking if your device supports it is essential.
