Screen Mirroring (Miracast) is a wireless technology that allows you to switch the media or cast it that’s playing on your smaller Android, Windows, or Apple device to a larger one instead for a better viewing experience.
That larger device is usually a television or media projector, often one you have set up in the media or living room of your home. Media you can cast includes but is not limited to personal photos and slideshows, music, videos, games, and movies, and can originate from the internet or an app like Netflix or YouTube.
Summary: Screen mirroring (sometimes called screen casting and Miracast) allows you to mirror your mobile device’s content to your TV screen. You will need to open the connection for screen mirroring on both your smartphone/tablet and your TV in order for the connection to work successfully.
Note:The protocol used to wirelessly mirror one screen to another is called Miracast, a word you might encounter as you learn more about the technology.
