If your Mac Mini is not displaying on your Promethean board and you need to switch inputs, follow these steps to troubleshoot the issue:
1. Check the connections: Ensure that the HDMI or VGA cable connecting your Mac Mini to the Promethean board is securely plugged in on both ends. If using an adapter, make sure it is also properly connected.
2. Restart the devices: Sometimes a simple restart can resolve connectivity issues. Turn off both the Mac Mini and the Promethean board, then power them back on.
3. Select the correct input: Use the remote control or buttons on the Promethean board to switch to the correct input source where the Mac Mini is connected. Make sure the input source matches the port you are using (HDMI or VGA).
4. Adjust display settings on the Mac Mini: If the Mac Mini is still not displaying on the Promethean board, go to System Preferences > Displays and check the resolution and refresh rate settings. Adjust them if necessary to match the capabilities of the Promethean board.
5. Update software: Make sure both the Mac Mini and the Promethean board have the latest software updates installed. Updating the software can sometimes resolve compatibility issues.
By following these steps, you should be able to successfully switch inputs and display your Mac Mini on the Promethean board. If the issue persists, contact our customer support team for further assistance.
