5. AMD FreeSync Technology
AMD FreeSync technology synchronizes the monitor's refresh rate with your GPU's frame rate, eliminating screen tearing and reducing stuttering for a smoother gaming experience.

Maintenance
1. Cleaning the Monitor
To clean the screen, gently wipe it with a soft, lint-free cloth. For stubborn marks, lightly dampen the cloth with water or a mild, non-abrasive screen cleaner. Avoid using alcohol-based cleaners or harsh chemicals. For the exterior, use a soft, dry cloth.
2. Environmental Care
Keep the monitor in a well-ventilated area, away from direct sunlight, excessive heat, or moisture. Avoid blocking the ventilation openings on the monitor's casing to prevent overheating.
Troubleshooting
No Power
- Ensure the power cable is securely connected to both the monitor and a working power outlet.
