**What Is Screen Mirroring: A Comprehensive Guide for Everyone?**

Screen mirroring lets you display content from your device on a bigger screen, and WHAT.EDU.VN is here to give you the full picture. It’s a simple way to share photos, videos, presentations, or anything else from your smartphone, tablet, or computer onto a TV, projector, or monitor. Dive in to discover the ins and outs of screen mirroring, its benefits, and how it differs from casting, ensuring you’re well-versed in display mirroring and wireless display technologies.

1. What Is Screen Mirroring and How Does It Work?

Screen mirroring duplicates the display of one device (like a smartphone, tablet, or computer) onto another, larger screen, such as a TV or projector. This is achieved through a wireless connection, typically using Wi-Fi or technologies like Miracast or AirPlay. This technology is useful for sharing content, presentations, or even gaming on a bigger screen.

Screen mirroring works by sending a real-time copy of your device’s screen to another display. It involves two key components: the sending device (your smartphone, tablet, or computer) and the receiving device (the TV, projector, or monitor). When you initiate screen mirroring, the sending device transmits a signal, either wirelessly or via a cable, to the receiving device. This signal contains all the visual data necessary to replicate what’s on your screen. The receiving device then interprets this signal and displays the content accordingly, effectively mirroring the screen.

1.1. What are the Key Technologies Behind Screen Mirroring?

Several technologies facilitate screen mirroring, each with its own strengths and compatibility.

Wi-Fi Direct: Allows devices to connect directly without needing a Wi-Fi network.
Miracast: A wireless display standard that allows devices to mirror their screens to compatible TVs or adapters.
AirPlay: Apple’s proprietary technology for streaming video, audio, and screen content between Apple devices.
Chromecast: Google’s technology that allows you to stream content from your devices to your TV.

1.2. How is Screen Mirroring Different From Casting?

Although frequently used interchangeably, screen mirroring and casting are distinct processes. Screen mirroring duplicates your device’s entire display onto another screen. Casting, on the other hand, streams specific content from an app to a receiving device, without mirroring the entire screen. For instance, when you cast a Netflix video from your phone to your TV, the TV streams the video directly from Netflix, allowing you to use your phone for other tasks.

Feature	Screen Mirroring	Casting
Display	Duplicates the entire screen	Streams specific content from an app
Device Usage	The sending device’s screen is mirrored	The sending device can be used for other tasks
Content Source	The sending device	The receiving device streams content directly
Example	Displaying a presentation from a laptop on a projector	Streaming a Netflix video from a phone to a TV
