  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. Verify that the connected input is enabled in the settings, and try checking and reconnecting the cable. If the signals from your PC's graphics card are out of the monitor's frequency range, refer to the Product Specification section of this manual to set the appropriate frequency.

Why is my LG 32UN550-W Monitor screen display unstable and shaky?
- R
  Roberto SmithAug 3, 2025
  If the screen display of your LG Monitor is unstable and shaky, or images leave shadow trails, and if 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 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.

Why does image sticking occur on my LG 32UN550-W even when turned off?
- S
  Shirley EspinozaAug 23, 2025
  If image sticking occurs on your LG Monitor even when it is turned off, it may be because displaying a still image for a prolonged time can cause damage to the screen, resulting in the retention of the image. To extend the lifetime of the monitor, use a screensaver.
