What to do if after-image appears on LG 55UM3DF?

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; try using the screen-saver function. Also, the appearance of a dark image after displaying an image with high contrast (black and white or gray) can cause image sticking, which is normal for LCD screen products.
