  Katie SchneiderAug 15, 2025
  If no image appears on your LG Monitor, first, ensure the power cord is correctly connected to the power outlet. Also, check the signal cable between your PC and the monitor to make sure it's properly connected. If the signal from the PC is out of the display's frequency range, consult the 'Specifications' section of the manual to reconfigure your display. You can unlock the OSD controls by entering the OSD lock menu and changing items to off. Verify the frequency or resolution settings in Control Panel - Display - Settings and readjust the video card to the recommended resolution, if necessary. Selecting the recommended resolution is crucial; otherwise, the screen may appear blurred, dimmed, truncated, or biased. If problems persist, consult the computer or video card manufacturer.

  The 'No image appears' message on your LG Monitor might be due to a few reasons. It could be that the power cord isn't properly connected to the outlet.

  If the display image on your LG Monitor is incorrect, ensure the signal cable is properly connected, tightening it with a screwdriver if needed. Also, make sure the video card is correctly inserted in its slot. Set the color setting higher than 24 bits (true color) via Control Panel - Settings. If the screen is set to interlace mode, change it to the recommended resolution. It's recommended to install the display driver from the LG website. Verify that your video card supports Plug&Play. If the selected resolution is HDMI 1080i 60/50 Hz, change it to the recommended resolution of 1080P.
