Always power off the monitor and unplug it before cleaning. Use a soft, lint-free cloth lightly dampened with water or a non-abrasive, monitor-specific cleaning solution.

When not in use for extended periods, store the monitor in a cool, dry place, away from direct sunlight and extreme temperatures. If possible, use the original packaging for protection.

Ensure the monitor's ventilation openings are not blocked. Proper airflow is essential to prevent overheating.
