  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. Also, check the connection status of the signal cable and re-insert the PC graphics card. Note that several pixels (red, green, blue, white, or black color) may appear on the screen due to the unique characteristics of the LCD panel, and this 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. Use the screen-saver function. Also, 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.
