Miracast is a technology that creates a wireless connection between your mobile device (phone, tablet, laptop) and a TV or projector. It allows you to mirror the content from your mobile device screen and display it on the larger screen. It makes it easy to share your favorite photos, movies, music, websites, presentations and more with friends and family.

Here’s some good news:  No connecting wires are required! You’re free to relax on the sofa while wirelessly sharing your mobile device content on the TV.

Better yet, Miracast technology does not use a home’s Wi-Fi network. Instead, it creates its own direct wireless signal between your mobile device and the TV. Therefore, it doesn’t slow down the home WiFi network.

Miracast History

The Wi-Fi Alliance developed Miracast in 2012. The technology is now built-in to most Android devices with 4.2 or later operating systems. It allows you to screen mirror without wires. It also works in other devices that support the technology, like Windows 10/11.

One of the best things about Miracast is that you’re not limited as to the type of content you can display. You can share photos and music, videos and other media from any Miracast-enabled device to your big screen TV.

How Miracast Works

With Miracast enabled devices, you don’t need to download an App. Many devices have Miracast technology built-in such as the Samsung Galaxy 8 and other Android phones. Devices with Windows 8 or 10 also have the technology built in.  

Miracast creates its own direct wireless signal between your mobile device and the wireless display receiver. This means you don’t have to rely on a home Wi-Fi network. All you need to make it work are two things: 

• First, your mobile device needs to be Miracast enabled. Devices like Samsung smartphones or other Android phones, as well as devices that use Windows 8 or 10, typically have the technology built-in.
• Second, you’ll need a Wireless Display Adapter like ScreenBeam’s ScreenBeam Mini2. These Adapters are also called Wireless Display Receivers. The Receiver plugs right into an available HDMI port on your TV and receives the signal from your mobile device.

Once you connect, you can share virtually any content from your mobile device screen on the TV.
