A New Wireless Screen Mirroring Option: Google Cast Makes Large Screens Smarter
In modern digital life, casting content from mobile devices to large screens has become a necessity. Whether for presentation needs in work meetings or the viewing experience of a home theater, wireless screen mirroring technology simplifies and enhances content sharing. This article will introduce how to achieve seamless cross-device screen mirroring using casting devices that support the Google Cast protocol.
What is Google Cast Technology?
Google Cast is a wireless screen mirroring protocol developed by Google, which allows users to cast content from mobile phones, tablets, or computers to display devices that support the protocol. Unlike traditional screen mirroring, Google Cast uses a “streaming” method—content is directly retrieved by the receiving device, delivering a more stable playback experience.
