What is Miracast?

Wireless screen mirroring technology for Android

I edit the home A/V and pro audio articles on It's a cool gig for a guy who's been seriously into audio since way before 1974. I started buying records, guitars, and gear with the money I made mowing lawns and delivering newspapers. Now the way I earn my money has changed for the better, but where it goes hasn't changed too much. Just give me the proverbial three chords and the truth. I'll do my best to help you feel it, too.

Miracast screen mirroring for Android

Use Miracast to display photos on your HDTV.

Devices with Miracast™ technology built in can share content wirelessly, without going through a home network. Send pictures, high-definition videos, and music from an Android™ phone or tablet to a big screen television. Display a laptop screen on the conference room projector, without plugging in. Or watch live TV programs from a cable box on your tablet.

Miracast-certified devices make connections via Wi-Fi Direct™ technology, so access to a Wi-Fi® network is not required. Miracast is built into Windows® 8.1 and Android 4.2 and above. Adapters are available for TVs that don’t have Miracast built in. Samsung uses the term AllShare Cast, rather than Miracast, to describe this screen mirroring capability.
