  If nothing is displayed on your LG Monitor screen, first, ensure the power cord is correctly plugged into the power outlet. Then, 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. Finally, check the signal cable between your PC and the monitor to ensure it's properly connected. If the issue persists, the signals from your PC might be out of the monitor's frequency range; refer to the Product Specification section of the manual to set the appropriate frequency.

Why is my LG 27UK500 Monitor screen display unstable and shaky?
- A
  Andrew WheelerAug 7, 2025
  An unstable or shaky display, or images leaving shadow trails on your LG Monitor, may occur if the selected resolution is HDMI 1080i 60/50 Hz (interlaced). Try changing the resolution to 1080p or the recommended resolution. If your graphics card isn't set to the optimal resolution, it may cause blurred text, a dimmed screen, a truncated display area, or misalignment. Setting methods vary, and some resolutions might not be available depending on your graphics card's performance.
