5. Maintenance
5.1 Cleaning the Monitor
To clean the monitor 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. Avoid using harsh chemicals, alcohol, or ammonia-based cleaners, as these can damage the screen surface. For the monitor casing, use a soft, dry cloth.
5.2 General Care
Avoid placing heavy objects on the monitor. Do not expose the monitor to direct sunlight, high temperatures, or high humidity. Ensure adequate ventilation around the monitor to prevent overheating.
6. Troubleshooting
If you encounter issues with your monitor, refer to the following common solutions:
- No Power: Ensure the power cord is securely connected to both the monitor and a working electrical outlet. Check if the power indicator light is on.
- No Signal: Verify that the video cable (HDMI or D-Sub) is correctly connected to both the monitor and your computer. Ensure the correct input source is selected in the monitor's OSD menu.
- Image Issues (e.g., blurry, distorted): Check the display resolution settings on your computer to ensure they match the monitor's native resolution (1920 x 1080). Adjust OSD settings like brightness, contrast, and sharpness if needed.
- Flickering or Tearing (in games): Ensure AMD FreeSync is enabled on both your monitor (via OSD) and your graphics card settings.
