  There could be several reasons why nothing is displayed on your LG monitor's screen. First, ensure the power cord is correctly plugged into the power outlet and that the power cable connection is secure, then press the power button. Also, verify that the connected input is enabled in the monitor's settings under the Input section. This issue can also occur if the signal cable between your PC and the monitor is either missing or disconnected, so check the cable and reconnect it securely.

  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.
