7. Maintenance
7.1. Cleaning the Monitor
- Always disconnect the power cable before cleaning.
- Use a soft, lint-free cloth slightly dampened with water or a mild, non-abrasive screen cleaner.

8. Troubleshooting
- No Signal / Power Saving Mode:
- Ensure the monitor is connected to the provided power adapter and receiving sufficient power.
- Try switching the Type-C cable head to the other side and reconnecting the monitor.
- Verify that your PC/Laptop's Type-C port supports audio and video signals (Thunderbolt 3 or DisplayPort Alternate Mode). If not, a "Type-C to HDMI" adapter may be required.
- Test with a different HDMI or USB-C cable if available.
- Poor Signal / Screen Flickering:
- Ensure you are using the original power adapter provided with the monitor, as insufficient voltage from other adapters can cause issues.
- Swap the HDMI cable to test if the cable is faulty.
- Touchscreen Not Responding:
- Remember that the touch function is not available when connected to Apple devices, PS3/4/5, Switch, X-box, Steam-Deck, Fire TV stick/cube, or similar devices.
- Ensure the USB-C cable is properly connected and supports data transfer for touch input.
- No Audio:
- Check the volume settings on both the monitor and your connected device.
- Ensure the correct audio output device is selected on your connected device.
- If using external speakers/headphones, ensure they are properly connected to the 3.5mm AUX port.
9. User Tips
- Optimal Viewing Angle: For best comfort and safety, place your monitor at or slightly below eye level. Avoid steep downward angles that may stress the stand, especially with larger screens.
- Safety Precaution: Due to the weight of the monitor, it is not recommended to place it above your head for safety reasons.
- Power Management: The monitor turns on in a default power save mode. Remember to manually close it if you do not want it to enter sleep mode.
- Device Compatibility: If your mobile phone or laptop's Type-C port does not support video output (DisplayPort Alt Mode), you may need an additional adapter (e.g., Type-C to HDMI) to connect. Refer to your device's specifications.
