  If the screen color on your LG Digital Signage is abnormal, set the number of colors to more than 24 bits (true color) by selecting [Control Panel] ? [Display] ? [Settings] ? [Color Table] in Windows. Check the connection status of the signal cable, and try re-inserting the PC graphics card. Note that this can be attributable to the unique characteristics of the LCD panel and is not a malfunction.

  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.
