  Nicholas JensenJul 28, 2025
  If nothing is displayed on your LG Monitor screen, first, ensure the power cord is correctly plugged into the power outlet. Next, verify the power cable connection and press the power button. Then, check that the connected input is enabled in the monitor settings (Settings > Input). If the issue persists, inspect the signal cable between your PC and the monitor, ensuring it's properly connected. Lastly, confirm that the signals transferred from your PC (graphics card) are within the horizontal or vertical frequency range supported by the monitor. Refer to the Product Specification section of the manual to set the appropriate frequency.

  If images are displayed without sound on your LG Monitor, ensure that the headphone port connections are correctly made. You can also try increasing the volume using the joystick on the monitor. Finally, set the audio output of your PC to the monitor you are using. Note that the exact settings may vary depending on your operating system.

What to do if LG 24QP750 screen display is unstable and shaky?

  If the screen display on your LG Monitor is unstable and shaky, or if images leave shadow trails, and the resolution is set to HDMI 1080i 60/50 Hz (interlaced), the screen may be flickering. Try changing the resolution to 1080p or the recommended resolution. In addition, 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. The setting methods may be different depending on the computer or operating system, and some resolutions may not be available depending on the performance of the graphics card. If this is the case, contact the manufacturer of the computer or graphics card for assistance.

  If some functions are not available when you press the Menu button on your LG Monitor, it might be because the OSD is locked. To resolve this, disable OSD Lock in the General settings.

  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.
