      If nothing is displayed on the LG Monitor screen, ensure the power cord is correctly plugged into the outlet. Also, verify the power cable connection and press the power button. Check that the connected input is enabled in the monitor's settings under [Settings] > [Input]. Finally, ensure the signal cable between the PC and the monitor is properly connected. If the issue persists, the signals from your PC may 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 32UL750 Monitor screen display unstable and shaky?

      elizabeth41Aug 8, 2025
      If your LG Monitor screen display is unstable or shaky, or if images leave shadow trails, it could be due to the resolution being set to HDMI 1080i 60/50 Hz (interlaced). Try changing the resolution to 1080p or the recommended resolution. Also, not setting the graphics card to the recommended resolution may result in a bad image quality. Contact the manufacturer of the computer or graphics card for assistance.
