Miracast is a wireless technology that allows users to mirror their device's screen to a compatible display, such as a TV or projector. It works over Wi-Fi Direct, enabling a direct connection between devices without needing a traditional network. This makes it easy to share videos, photos, and presentations from smartphones, tablets, or laptops. The technology supports high-definition video and audio streaming, providing a seamless viewing experience. Many modern devices, including those running Android and Windows, come with built-in support for Miracast, making it a convenient option for users looking to share content wirelessly.
