3. Daily Use and Maintenance

3.1 Cleaning the Screen

1. Turn off the power and unplug the power cord.
2. Gently wipe the screen with a soft microfiber cloth.
3. For stubborn stains, apply a small amount of dedicated screen cleaner to the cloth. Never spray cleaner directly onto the screen, as liquid could seep into the edges and damage components.
4. Do not use chemical solvents such as alcohol, ammonia, or glass cleaner, as they can damage the screen's coating.

3.2 Best Practices

• Avoid displaying static images (e.g., desktop icons, taskbar) for extended periods to prevent minor "image retention" (burn-in, which is less common on LCDs than OLEDs but still possible).
• Use the automatic sleep and screensaver functions in Windows or macOS.
• Avoid pressing hard on or touching the screen surface with sharp objects.
• Ensure good ventilation around the device and avoid using it in excessively hot or humid environments.
