Why does after-image appear on my LG 43SE3DD?
- A
  Anthony KirbySep 17, 2025
  If an after-image appears on your LG Monitor when it is turned off, and you have been using a fixed image for a long time, the pixels may be damaged. Use the screen-saver function. When a dark image is displayed on the screen after an image with high contrast (black and white or gray), this may cause image sticking. This is normal for LCD screen products.
