  If nothing is displayed on your LG Monitor, first, ensure the power cord is correctly plugged into the power outlet. Next, check the power cable connection and press the power button. Also, verify that the connected input is enabled in the monitor's settings under 'Input'. If the issue persists, check the signal cable between your PC and the monitor, ensuring it's properly connected. Finally, the signals from your PC might be outside the monitor's frequency range; check the Product Specification section of this manual to set the appropriate frequency.

Why is my LG Monitor screen display unstable and shaky?
- H
  Heidi RussellAug 13, 2025
  If the screen display on your LG Monitor is unstable and shaky, or if images leave shadow trails, and you are using HDMI 1080i 60/50 Hz (interlaced) resolution, the screen may be flickering. Try changing the resolution to 1080p or the recommended resolution. Also, not setting the graphics card to the recommended (optimal) resolution may result in blurred text, a dimmed screen, a truncated display area, or misalignment of the display. Setting methods may vary depending on your computer or operating system, and some resolutions may not be available depending on the performance of the graphics card.
