Step-by-Step Instructions

Step 1: Use the CommBox Connect App

  • Ensure your Windows device and CommBox screen are connected to the same Wi-Fi network.

  • Open the CommBox Connect app on your personal device
  • Enter the device code and use quick connection to find the CommBox screen in your room.

💡 Tip: Avoid guest or public Wi-Fi networks—they often block device discovery.

Step 2: Use Miracast - Windows + K

  • On your CommBox screen, tap CommBox Connect.

  • Go to Menu > Settings

  • Ensure Miracast is turned on under supported protocols.

  • Press Windows + K on your keyboard
