Troubleshooting: The manual provides a comprehensive troubleshooting guide for common issues:

Power LED Not ON: Check power button, power cord connection, and grounded outlet.
No Images on Screen: Verify power cord, signal cable (VGA, HDMI, DP) connections, reboot computer, check for "Input Not Supported" message (adjust resolution/frequency if seen), and ensure AOC Monitor Drivers are installed.
Fuzzy/Ghosting Picture: Adjust Contrast/Brightness, use auto-adjust, avoid extension cables/switch boxes, and connect directly to the video card.
Picture Bounces/Flickers/Wave Pattern: Move electrical devices away, use maximum refresh rate for current resolution.
Monitor Stuck in Active Off-Mode: Check computer power, video card fit, monitor video cable connection, and ensure no bent pins. Verify computer operation using CAPS LOCK key.
Missing Primary Colors: Inspect monitor's video cable for damage and proper connection.
Screen Image Not Centered/Sized: Adjust H-Position and V-Position or use auto-adjust hotkey.
Color Defects: Adjust RGB color or select desired color temperature.
Horizontal/Vertical Disturbances: Use Windows 7/8/10 shut-down mode to adjust CLOCK and FOCUS, or press auto-adjust.

Safety Precautions:

Operate the monitor only from the specified power source.
Use a grounded plug and outlet; do not defeat the safety purpose of the grounded plug.
