What is screen mirroring?

Screen mirroring is the process of displaying content from one screen onto another screen. These screens can be on the same device, such as multiple monitors or displays on a computer, or adaptors designed to help one device display onto another device.

Mirroring can be used for business and educational purposes, by allowing many viewers to observe a presentation or educational software run from a larger, primary display. The presenter controls the software from his own main screen.

Screen mirroring also has entertainment purposes, allowing users to display audio and video from the Internet on a television at home. Devices such as the Google Chromecast or Apple TV allow users to mirror content onto televisions from a tablet or computer.
