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 smudges, use a monitor-specific cleaning solution applied to the cloth, not directly to the screen.
- Cleaning the Casing: Use a soft, dry cloth to clean the monitor casing. Avoid abrasive cleaners.
- Ventilation: Ensure the monitor's ventilation openings are clear and not obstructed to prevent overheating.
- OLED Care Features: This monitor may include features like Pixel Shift, Panel Protect, and Pixel Refresh designed to mitigate potential OLED burn-in. Consult the OSD menu for these settings and enable them as recommended for optimal panel health.
8. Troubleshooting
If you encounter issues with your monitor, refer to the following common troubleshooting steps:
- No Power: Check if the power cable is securely connected to both the monitor and the power outlet. Ensure the power outlet is functional.
- No Signal: Verify that the video cable (DisplayPort, HDMI, or USB-C) is correctly connected to both the monitor and your computer/device. Ensure the correct input source is selected in the OSD menu.
- Flickering/Image Issues: Check your graphics card drivers for updates. Ensure the video cable is not damaged. Try a different cable or port. For OLED-specific flickering, especially with Variable Refresh Rate (VRR), ensure your monitor's firmware is updated to the latest version (e.g., version 011 or newer, as mentioned in some reviews, for optimal input lag and VRR performance).
- Poor Picture Quality: Adjust brightness, contrast, and color settings in the OSD menu. Ensure the monitor is set to its native resolution (3840 x 2160) and desired refresh rate (144Hz).
- Burn-in/Image Retention: While OLED technology has advanced, static images displayed for extended periods can still pose a risk. Utilize the monitor's built-in OLED care features (Pixel Shift, Panel Protect, Pixel Refresh) to minimize this risk. Avoid displaying static elements (like taskbars or desktop icons) for prolonged durations.
