  If no image is displayed on your LG Digital Signage, consider the following: * Ensure the power cord is properly connected to the outlet. * Verify the signal cable between the PC and the product is connected correctly. * Use the 'INPUT' menu on the remote control to check the input signal. * If the signal from the PC is out of the vertical or horizontal frequency range, adjust the frequency range by referring to the specifications. The maximum resolution is 1920 x 1080 @ 60 Hz.

  If an after-image appears on your LG Monitor, and you've been using a fixed image for a long time, the pixels may be damaged quickly. Use the screen-saver function. Also, when a dark image is displayed after an image with high contrast, it may cause image sticking, which is normal for LCD screens.

  If the operation of your LG Monitor does not work normally, check if the sleep timer is set or if there are any power control settings enabled. A power interruption could also be the cause.

Why is the screen color abnormal on my LG Monitor?

  Margaret PatelAug 27, 2025
  If your LG Monitor's screen color is abnormal, set the number of colors to more than 24 bits (true color) by selecting Control Panel - Display - Settings - Color Table menu in Windows. Also, check the connection status of the signal cable and re-insert the PC video card. Note that several pixels (red, green, white or black color) may appear on the screen, which is attributable to the unique characteristics of the LCD panel and not a malfunction.

  If the screen image on your LG Monitor looks abnormal, for a D-Sub analog signal, press the AUTO button on the remote control to automatically select the optimal screen status. If this isn't satisfactory, use the Position, Clock or Phase OSD menus for further adjustments. Ensure that your video card resolution and frequency are supported by the monitor; if the frequency is out of range, set it to the recommended resolution in the Control Panel Display Setting menu. Also, make sure the correct input signal is connected to the appropriate signal port.
