5. Troubleshooting
If you encounter issues with your monitor, consider the following common solutions:
- No Display/Signal: Ensure all cables (USB-C, HDMI) are securely connected and that the monitor is receiving sufficient power from the provided adapter. Try reconnecting cables in the specified order for your device type.
- Touchscreen Not Working: For Windows, ensure the touchscreen is set as the main display in your system settings. For macOS, only 1-point touch is supported. iOS/iPadOS devices do not support touch. Verify that the correct USB-C port is used for touch data (refer to setup instructions).

- Audio Issues: Ensure the monitor's volume is not muted or too low. Check your device's audio output settings to confirm sound is routed to the monitor.
