    What to do if nothing is displayed on my LG 34GN850 Monitor screen?

      Peter KelleyJul 28, 2025
      If nothing is displayed on your LG Monitor screen, first ensure the power cord is correctly plugged into the power outlet. Then, check the power cable connection and press the power button. Also, verify that the connected input is enabled in the monitor's settings (Settings > Input). If the monitor is in sleep mode, move the mouse or press any key on the keyboard. Confirm that your computer is turned on. If the issue persists, check the signal cable between the PC and the monitor to ensure it is properly connected. Finally, install the display driver from the LG website and verify that your graphics card supports Plug and Play.

      Karen GutierrezAug 11, 2025
      Displaying a still image for a prolonged time may cause damage to the screen of your LG Monitor, resulting in the retention of the image. To extend the lifetime of the monitor, use a screensaver.

    Why is the display color abnormal on my LG 34GN850?
    • P
      padillakaylaAug 17, 2025
      If the display color on your LG Monitor appears abnormal, try the following: First, set the color to 24 bit (true color) or higher by navigating to Control Panel > Display > Settings > Color Quality in Windows. Next, check the signal cable connection and 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.
