      If no image appears on your LG Digital Signage, verify that the power cord is properly connected to the outlet. If you see an “Invalid Format” message, the signal from your PC might be outside the product's frequency range; adjust it within the specifications in this manual. If a “No Signal” message appears, ensure the signal cable between the PC and the product is securely connected and that the correct input signal is selected in the input menu.

    Why is the screen color abnormal on my LG 75UM3E-B.AUS?

      If your LG Digital Signage displays poor color resolution (16 colors), increase the color depth to more than 24 bits (true color) via Control Panel - Display - Settings - Color Table in Windows. If the screen color is unstable or mono-colored, check the signal cable connection or try re-inserting the PC graphics card. Note that a few colored pixels may appear due to the unique characteristics of the LCD panel and do not indicate a malfunction.

      If the screen position is wrong, check that the graphics card resolution and frequency are supported by the LG Digital Signage. If the frequency is out of range, set the resolution in the Control Panel Display Setting menu. If the screen is displayed abnormally, ensure the correct input signal is connected to the appropriate signal port.

      If an after-image appears on your LG Digital Signage after it's turned off, and you've been using a fixed image for a long time, the pixels may be damaged. Use the screen-saver function. Also, displaying a dark image after a high-contrast image may cause image sticking, which is normal for LCD screens.
