  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. Finally, the signals transferred from the PC (graphics card) might be out of the monitor's horizontal or vertical frequency range. Refer to the Product Specification section of the manual to set the appropriate frequency.

  If you are experiencing an unstable and shaky screen display or shadow trails on your LG Monitor, and the resolution is set to HDMI 1080i 60/50 Hz (interlaced), the screen may be flickering. Try changing the resolution to 1080p or the recommended resolution. Also, ensure that your graphics card is set to the recommended (optimal) resolution. If not, it may result in blurred text, a dimmed screen, a truncated display area, or misalignment. If issues persist, contact the manufacturer of your computer or graphics card for assistance.
