[Color Table] in Windows. Check the connection status of the signal cable, and try re-inserting the PC graphics card.

  If an after-image appears on your LG Digital Signage, and you use a fixed image for a long time, it may damage the pixels, so 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, which is normal for LCD screen products.
