  If nothing is displayed on your LG Monitor screen, ensure the power cord is correctly plugged into the power outlet. Also, verify the power cable connection and press the power button. Check that the connected input is enabled in the monitor settings. If the signal cable between your PC and the monitor is missing or disconnected, check the cable and reconnect it. If the signals from your PC are out of the monitor's frequency range, consult the Product Specification section of the manual to set the appropriate frequency.

  Lori SmithAug 2, 2025
  If the screen display on your LG Monitor is unstable and shaky, or if images leave shadow trails, the selected resolution might be HDMI 1080i 60/50 Hz (interlaced). Try changing the resolution to 1080p or the recommended resolution. Note that not setting the graphics card to the recommended resolution may result in blurred text, a dimmed screen, a truncated display area, or misalignment of the display. Setting methods vary depending on the computer or operating system, and some resolutions may not be available depending on the performance of the graphics card.
