  If nothing is displayed on your LG Monitor screen, verify that the power cord is correctly plugged into the power outlet.

Finally, check the signal cable and reconnect it if missing or disconnected.

Why is my LG 34WP85C Monitor screen display unstable and shaky?
- R
  Robin AustinAug 2, 2025
  If your LG Monitor's screen display is unstable, shaky, or images leave shadow trails, and the resolution is HDMI 1080i 60/50 Hz (interlaced), the screen may be flickering. Try changing the resolution to 1080p or the recommended resolution. Also, ensure that the graphics card is set to the recommended (optimal) resolution to avoid blurred text, a dimmed screen, a truncated display area, or misalignment of the display. Setting methods may vary 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.

Why does image sticking occur even when my LG Monitor is turned off?
- J
  John VazquezAug 18, 2025
  If image sticking occurs on your LG Monitor even when it is turned off, it may be due to displaying a still image for a prolonged time, which can cause damage to the screen and result in image retention. To extend the lifetime of the monitor, use a screensaver.
