      If your LG Monitor displays nothing, it could be due to a missing or disconnected signal cable between your PC and the monitor. Check the cable and reconnect it securely. Also, the signals transferred from the PC (graphics card) might be out of the horizontal or vertical frequency range of the monitor. Refer to the Product Specification section of this manual to set the appropriate frequency.

      If images are displayed without sound on your LG Monitor, first ensure that the headphone port connections are properly made. If that's not the issue, try increasing the volume using the joystick. Finally, set the audio output of your PC to the monitor you are currently using. Note that the settings may vary depending on your operating system.

      Elaine CaldwellSep 22, 2025
      If image sticking occurs on your LG Monitor even when it's turned off, it may be due to displaying a still image for a prolonged time, which can cause damage to the screen. To extend the monitor's lifetime, use a screensaver.

    What to do if my LG 34WN780-B.AAU screen display is unstable and shaky?
    • B
      Brian MyersSep 4, 2025
      If your LG monitor's screen display is unstable or shaky, or if 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. Also, 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.
