  If nothing is displayed on your LG Monitor screen, start by checking if the power cord is correctly plugged into the power outlet. Also, verify the power cable connection and ensure you press the power button. Make sure the connected input is enabled in the monitor's settings under Input. If the monitor is in sleep mode, try moving the mouse or pressing a key on the keyboard. Confirm that your computer is turned on. If the signal cable between the PC and the monitor is missing or disconnected, check the cable and reconnect it. Finally, ensure you install the display driver from the LG website and that your graphics card supports Plug and Play.

  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. Then, check if the signal cable is properly connected; reconnect the cable or reinsert the PC's graphics card. Note that pixilated spots (red, green, blue, white, or black) may appear, which is normal and not related to the monitor's performance.

  If your LG Monitor's screen display is unstable, shaky, or images leave shadow trails, it might be due to the resolution being set to HDMI 1080i 60/50 Hz (interlaced). Try changing the resolution to 1080p or the recommended resolution.
