  If nothing is displayed on your LG monitor screen, ensure the power cord is correctly plugged into the power outlet. Also, check the power cable connection and press the power button. Try changing the input by pressing the / key. If the signal cable between the PC and the monitor is missing or disconnected, check the cable and reconnect it. This issue can also occur if signals transferred from the PC (graphics card) are out of the horizontal or vertical frequency range of the monitor. In this case, refer to the Product Specification section of this manual to set the appropriate frequency.

  If your LG monitor's screen display is unstable and shaky, or if images displayed on the monitor leave shadow trails, and the selected resolution is HDMI 1080i 60/50 Hz (interlaced), the screen may be flickering. 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. 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 image sticking occurs even when your LG monitor is turned off, it may be due to displaying a still image for a prolonged time, which can cause damage to the screen, resulting in the retention of the image. To extend the lifetime of the monitor, use a screensaver.
