7. Maintenance

To ensure the longevity and optimal performance of your monitor, follow these maintenance guidelines:

• Cleaning the Screen: Gently wipe the screen with a soft, lint-free cloth. For stubborn marks, lightly dampen the cloth with water or a screen-cleaning solution specifically designed for monitors. Avoid using harsh chemicals, abrasive cleaners, or alcohol-based solutions.
• Cleaning the Casing: Use a soft, dry cloth to wipe the monitor casing. Do not use liquid cleaners directly on the monitor.
• Ventilation: Ensure the ventilation openings on the monitor are not blocked. Proper airflow prevents overheating.
• Power Off: Always power off the monitor and unplug it from the power outlet before cleaning or when it will not be used for an extended period.

8. Troubleshooting

If you encounter any issues with your monitor, refer to the following common troubleshooting steps:

• No Display/Black Screen:
  • Check if the power cord is securely connected to both the monitor and the power outlet.
  • Verify that the video cable (Thunderbolt 3, DisplayPort, or HDMI) is correctly connected to both the monitor and your computer.
  • Ensure the correct input source is selected on the monitor via the OSC menu.
  • Try connecting the monitor to a different video output on your computer or another computer to rule out a source issue.
• No Sound from Built-in Speakers:
  • Check the volume level on the monitor via the OSC menu and on your computer.
  • Ensure the audio output on your computer is set to the LG 34WK95U-W monitor.
  • If using HDMI, ensure the HDMI-CEC setting is enabled on the monitor if applicable (check advanced settings).
• Image Retention/Ghosting:
  • This can sometimes occur after displaying a static image for a long period. Lowering contrast and using a white screen saver can help mitigate this.
  • If persistent, contact LG support.
• Mac Compatibility Issues (Thunderbolt 3):
  • Ensure your macOS is updated to the latest version, especially for newer MacBooks (e.g., Mac OS X 10.14.2 Beta or later for 2018 models).
