  If your LG monitor displays nothing, several factors could be the cause. First, ensure the power cord is correctly plugged into the outlet and that the power cable is properly connected; then, press the power button. Also, confirm that the connected input is enabled via Menu > Input. If the monitor is in sleep mode, try moving the mouse or pressing a key on the keyboard. Verify that your computer is turned on. If you see a message indicating a missing or disconnected signal cable, check the cable and reconnect it. Finally, make sure to install the display driver from the LG website and check if your graphics card supports Plug and Play.

  If your LG monitor screen display is unstable or shaky, and/or images displayed on the monitor leave shadow trails, and if the selected resolution is HDMI 1080i 60/50 Hz (interlaced), the screen may be flickering. Change the resolution to 1080p or the recommended resolution.

  If the display color on your LG monitor appears abnormal, first set the color to 24 bit (true color) or higher via Control Panel > Display > Menu > Color Quality in Windows. Also, check the signal cable connection; reconnect it or reinsert the PC's graphics card. Note that small, colored spots (red, green, blue, white, or black) may appear, which is normal and not related to the monitor's performance.
