  If your LG Monitor displays no image, there could be several reasons. First, ensure the power cord is properly connected to the power outlet. Second, check the signal cable between your PC and the monitor to make sure it is connected correctly. Finally, if a message appears indicating the signal from the PC (video card) is out of the display's frequency range, consult the 'Specifications' section of the manual and configure your display settings accordingly.

  If the display image on your LG Monitor is incorrect, there are several troubleshooting steps you can take. First, check that the signal cable is properly connected, using a screwdriver to tighten it if needed. Next, ensure the video card is correctly inserted in its slot. Then, set the color setting higher than 24 bits (true color) via Control Panel settings. Also, change the resolution to the recommended resolution, ideally 1080P. Ensure you have installed the display driver from the LG website. Finally, verify that the video card supports the Plug&Play function.
