Maintenance

OLED Protection and Care

To maintain the performance and longevity of your OLED panel, utilize the built-in OLED Care tools. These tools include features like pixel cleaning, which helps prevent image retention and ensures a sharp display over time. Regular use of these features is recommended.

Troubleshooting

If you encounter issues with your monitor, refer to the following common solutions:

• Flickering Issues: If the screen flickers, try adjusting the Adaptive Sync settings in the monitor's OSD menu. Switching from 'Extended' to 'Basic' or 'Off' can resolve this.
• DisplayPort Connectivity: If you experience issues with non-native resolutions when using DisplayPort, consider using an HDMI 2.1 cable as an alternative. Ensure your graphics card drivers are up to date.
• Monitor Not Turning On: Verify that the power cable is securely connected to both the monitor and a working power outlet. If the issue persists, the power supply unit may require inspection.
• Image Retention / Red Dots: Utilize the OLED Care tools, such as pixel cleaning, available in the monitor's settings to address potential image retention or pixel anomalies.
• Grainy/Static/Screen Door Effect: This can sometimes be observed with the matte screen surface, particularly in dark environments when displaying static gray content. It is generally less noticeable during dynamic content or in well-lit rooms.
