Maintenance

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. Avoid using harsh chemicals, alcohol, or ammonia-based cleaners, as these can damage the screen surface.

2. General Care

Keep the monitor in a well-ventilated area, away from direct sunlight, heat sources, and excessive dust. Do not block the ventilation openings. Avoid placing heavy objects on the monitor or its cables. Disconnect the power cord during lightning storms or when the monitor will be unused for extended periods.

Troubleshooting

If you encounter issues with your LG 34WL750-B monitor, refer to the following common troubleshooting steps:

• Display Flickering: Check the video cable for damage or loose connections. Try a different video cable or input port. Ensure your graphics card drivers are up to date. If the issue persists, it may indicate a hardware problem requiring service.
• Image Distortion or Incorrect Colors: Reset the monitor to its factory default settings via the OnScreen Control menu. Adjust color settings on your computer's display settings.
