5. Maintenance
To ensure the longevity and optimal performance of your AOC GAMING CQ27G3S monitor, follow these maintenance guidelines:
- Cleaning the Screen: Gently wipe the screen with a soft, lint-free cloth. For stubborn marks, lightly dampen the cloth with water or a non-abrasive screen cleaner. Avoid spraying liquid directly onto the screen.
- Cleaning the Casing: Use a soft, dry cloth to clean the monitor's casing. Do not use abrasive cleaners or solvents.
- Ventilation: Ensure the ventilation openings on the monitor are not blocked to prevent overheating.
- Power Off: Always turn off the monitor and unplug it from the power outlet before cleaning or if it will not be used for an extended period.
6. Troubleshooting
If you encounter issues with your monitor, please refer to the following common troubleshooting steps:
- No Power: Ensure the power cord is securely connected to both the monitor and the power outlet. Try a different power outlet if available.
- No Signal: Verify that the HDMI or DisplayPort cable is firmly connected to both the monitor and your computer. Ensure the correct input source is selected on the monitor's OSD menu.
- Blank Screen / Unresponsive Controls: If the monitor turns on but the screen remains black or the control buttons are unresponsive, try disconnecting the power cable from the monitor for a few minutes, then reconnecting it. If the issue persists, it may indicate an internal hardware problem.
- Image Issues (Blurry, Distorted, etc.): Check your computer's display settings to ensure the resolution and refresh rate are set correctly (2560x1440 at 165Hz for optimal performance). Update your graphics card drivers.
- Flickering: Ensure the refresh rate is set correctly. If Adaptive-Sync/G-SYNC is enabled, try disabling it temporarily to see if the issue resolves.
