Having trouble connecting your device to an i3CONNECT interactive display using Miracast? In rare cases, you may not be able to find the i3CONNECT interactive display in your laptop's search list or you receive warning messages such as "Couldn't connect."
Miracast issues can happen if your device or display is on the wrong Wi-Fi band, after a Windows update, or due to driver/firewall settings. This guide helps you resolve these common Miracast connection issues when using AllSync.
Before you start
-
Make sure both your device and the i3CONNECT display are disconnected from any local Wi-Fi network.
-
Remove any saved Wi-Fi networks from your device that are for the touch-display you are having issues with.
Instructions
-
Switch Wi-Fi band: If your display is on a 5 GHz Wi-Fi network, switch it to 2.4 GHz. This avoids compatibility issues with some devices.
After changing the Wi-Fi band, reboot both the display and your device before retrying.
-
Check for Windows 11 24H2 issues: If you recently updated to Windows 11 24H2 and Miracast stopped working, try these fixes:

Troubleshooting
-
If you previously connected to this display, double-check that the display name matches in Bluetooth & devices > Devices > Wireless displays & docks.
-
If Miracast still doesn’t work after all steps, your device may not support Miracast or there may be a hardware issue.
-
For persistent issues, contact i3CONNECT support with your device and display details.
