      If your LG Monitor screen is blank, ensure the power cord is securely connected to the outlet. Also, verify the power cable connection and press the power button. Check that the connected input is enabled in the monitor settings (Settings > Input). If the signal cable is disconnected, check the cable and reconnect it. Finally, if the PC's graphics card signals are outside the monitor's frequency range, refer to the Product Specification section of this manual to set the appropriate frequency.

      Dennis DunnAug 3, 2025
      If the display on your LG Monitor is unstable or shaky, or if images leave shadow trails, and the resolution is HDMI 1080i 60/50 Hz (interlaced), try changing the resolution to 1080p or the recommended resolution. Also, make sure the graphics card is set to the recommended resolution to avoid blurred text, a dimmed screen, or misalignment.

    Why are some functions not available when I press the Menu button on my LG 34WQ73A-B?

      If some functions are unavailable when you press the Menu button on your LG Monitor, it may be because the OSD is locked. To resolve this, disable OSD Lock in the General settings.
