  If your LG Monitor screen is blank, ensure the power cord is securely 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 settings. If the signal cable between your PC and the monitor is missing or disconnected, check the cable and reconnect it.

  If your LG Monitor screen is unstable or shaky, and you're using HDMI 1080i 60/50 Hz (interlaced) resolution, the screen may flicker. Try changing the resolution to 1080p or the recommended resolution. Also, not setting the graphics card to the recommended resolution may cause blurred text, a dimmed screen, a truncated display area, or misalignment of the display.

  If the screen display on your LG Monitor is unstable and shaky, or if images leave shadow trails, 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. In addition, not setting the graphics card to the recommended (optimal) resolution may result in blurred text, a dimmed screen, a truncated display area, or misalignment of the display. The setting methods may be different depending on the computer or operating system, and some resolutions may not be available depending on the performance of the graphics card. If this is the case, contact the manufacturer of the computer or graphics card for assistance.
