To use Miracast, you'll need a device that supports the technology, such as a smartphone, tablet, or laptop, and a Miracast-enabled display, like a smart TV or projector.

Miracast creates a direct wireless connection between the device and the external display, working similarly to an ad hoc network.

It doesn't require your Wi-Fi router, and instead uses Wi-Fi Direct, allowing two devices to communicate directly.

A wireless connection is established between the two devices when sending content from a mobile device to a compatible television through the Miracast feature.

The direct wireless connection is created by the external display that your device can connect to, using WPS wireless network standards and secured using WPA2.

This makes a connection with Miracast quite secure, allowing you to stream image and sound from your device onto the external screen.

Miracast works by transmitting video and audio data wirelessly from the source device to the display device, over the Wi-Fi Direct connection.

The display device then decompresses and displays the content on its screen, with a resolution up to 1080p full HD and 5.1 surround sound.
