Miracast: Share your Windows / Android screen without an app on an i3CONNECT display

Wirelessly share your windows-brands-solid.png Windows laptop or android-brands-solid-full.svg Android device screen to an i3CONNECT display using Miracast, built into the AllSync app. Miracast lets you stream video and audio directly, without needing to be on the same Wi-Fi network.

If you only see your desktop background or run into connection issues, check the troubleshooting section below. This guide is for anyone using an i3CONNECT display with a Windows or Android device. If you’re using an Apple device, see the AirPlay instructions instead.

Good to know

  • You don’t need to be on the same network with Windows because Windows uses Miracast, which connects directly to the display and not over the internet.

  • The display and your device will disconnect from the WiFi while the screen mirroring process is active. This is the expected behaviour

  • On an Android device, the cast feature might be called ‘Screencast’ or ‘SmartView’.

Instructions

  1. Open the AllSync display app by pressing on Subtract.png Present on the home-screen / the side-bar.

  1. Open the Connect list and find the display:

    1. Windows: Press on the Windows button windows-brands-solid.png + K, or click the Action Center icon in the bottom right of your screen, and then click on computer-regular.png Cast (Windows 11) or computer-regular.png Connect (Windows 10).

    2. Android: Start the Casting app. The cast feature might be called “Screencast” or “SmartView.”

  2. Select your tv-solid.png Display from the list of available devices.

  3. Follow any additional instructions on the screen.

If you only see your desktop background (no apps), your computer may be in Extended Mode. To see a copy of your screen:

  1. Press windows-brands-solid.png Windows key + P to open the clone-regular.png Project menu (found in the Action Center).

  2. Select “Duplicate” to mirror your screen on the display.

Troubleshooting

  • If the display disconnects from WiFi during mirroring, this is normal. Miracast creates a direct connection and disables the internet during casting.

  • You don’t need to be on the same WiFi network. Miracast connects directly between your Windows device and the display.

  • If your device doesn’t appear, ensure Miracast is supported and both devices are close together.

  • If you still can’t connect, restart both your Windows/Android device and the i3CONNECT display, then try again.
