  If nothing is displayed on your LG Monitor screen, ensure the power cord is securely plugged into the power outlet. Also, check the signal cable between your PC and the monitor to make sure it is properly connected. If the issue persists, the signals from your PC might be outside the monitor's frequency range.

  If your LG Monitor's screen display is unstable or images leave shadow trails, and you're using HDMI 1080i 60/50 Hz (interlaced) resolution, the screen may flicker. Try changing the resolution to 1080p or the recommended resolution. Also, ensure your graphics card is set to the recommended resolution; otherwise, text may appear blurred, the screen dimmed, or the display area truncated. If issues persist, contact your computer or graphics card manufacturer for assistance.
