6. Maintenance
6.1 OLED Care 2.0 Features
Your monitor is equipped with OLED Care 2.0, a suite of features designed to prevent image retention and burn-in, common concerns with OLED panels. These features operate automatically in the background or prompt you for action.
- Pixel Shift: Periodically shifts pixels to prevent static images from causing burn-in.
- Panel Protect: A pixel refresh cycle that runs after a certain period of use (e.g., 4 hours, or configurable up to 24 hours via firmware updates). This process takes approximately 6-8 minutes and the monitor will be unusable during this time. It is recommended to allow this process to complete when prompted.
- Static Logo Detection: Automatically dims static logos or UI elements to reduce burn-in risk.
To ensure optimal panel health, it is recommended to allow the monitor to enter standby mode when not in use, as this often triggers maintenance cycles.
6.2 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 non-abrasive screen cleaner.
- Do not spray cleaner directly onto the screen.
- Avoid using alcohol-based cleaners, ammonia, or abrasive materials.
