  If nothing is displayed on your LG Monitor, try these steps: First, check if the power cord is correctly plugged into the power outlet and test the outlet with another device. Then, verify the power cable connection and press the power button on the monitor. Ensure that the connected input source is enabled in the monitor settings (Settings > Input > Input list). If the monitor is in sleep mode, move the mouse or press any key on the keyboard. Also, make sure your computer is turned on. Check the signal cable and reconnect it properly. If the issue persists, the signals from your PC might be out of range. Refer to the Product Specification section of the manual to set the appropriate frequency.

  If your LG Monitor screen display is unstable and shaky, or images leave shadow trails, and if the selected resolution is HDMI 1080i 60/50 Hz (interlaced), the screen may be flickering. Try changing the resolution to 1080P or the recommended resolution.

  Beverly BrownAug 10, 2025
  If the display color on your LG monitor is abnormal, first, set the color to 24 bit (true color) or higher by navigating to Control Panel > Display > Settings > Color Quality in Windows. Next, check if the signal cable is properly connected, and if not, reconnect it or reinsert the PC's graphics card. Note that pixilated spots (red, green, blue, white, or black) may appear on the screen, which is normal for an LCD screen and not related to the monitor's performance.
