What Is Screen Mirroring and How to Use It

Screen mirroring has become an essential feature in modern smartphones, smart TVs, and computers. Whether you want to watch movies on a bigger screen, share a presentation, or display photos to your family, screen mirroring makes it effortless. It helps you duplicate your phone or computer screen onto a larger display wirelessly or using a cable. This guide explains what screen mirroring is, how it works, and how you can use it on different devices.

What Is Screen Mirroring

Screen mirroring is a technology that allows you to project the exact screen of your smartphone, tablet, or computer onto another display such as a smart TV, projector, or monitor. Whatever you do on your device—open apps, scroll social media, play videos, or show documents—appears in real time on the larger screen.

It is different from casting. Casting sends only specific content like videos or music to the TV, while screen mirroring duplicates your entire device screen.

How Screen Mirroring Works

Screen mirroring uses wireless communication protocols that allow devices to connect and share data. The most commonly used technologies include:

Miracast
A wireless display standard that connects Android devices or Windows PCs to compatible TVs without Wi-Fi.

Chromecast (Google Cast)
A device or built-in feature that streams your screen from Android, Chrome browser, or apps to a TV.

AirPlay

Apple’s wireless technology for mirroring iPhone, iPad, or Mac screens to Apple TV or AirPlay-supported smart TVs.
