Why after-image appears on LG 47LS55A?
If an after-image appears on your LG Digital Signage, and you've been using a fixed image for a long time, the pixels may be damaged. Use the screen-saver function to prevent this. Also, when a dark image is displayed after an image with high contrast, image sticking may occur, which is normal for LCD screens.
