Maintenance
Cleaning the Monitor
To clean the screen, gently wipe it with a soft, lint-free cloth. For stubborn marks, lightly dampen the cloth with water or a mild, non-abrasive screen cleaner.

Troubleshooting
If you encounter issues with your monitor, refer to the following common problems and solutions:
- No Power: Ensure the power cable is securely connected to both the monitor and a working power outlet. Check if the power adapter is functioning correctly.
