6. Maintenance

6.1 Cleaning the Monitor

• Always power off the monitor and unplug the power cord before cleaning.
• Use a soft, lint-free cloth lightly dampened with water or a mild, non-abrasive screen cleaner.

• Avoid using benzene, thinner, ammonia-based cleaners, or abrasive materials, as these can damage the screen surface.

6.2 OLED Care and Burn-in Prevention

OLED technology offers superior image quality but requires specific care to prevent image retention (burn-in). The ASUS ROG Swift PG34WCDM incorporates features to mitigate this risk:
