  If the screen color is abnormal on your LG Digital Signage, set the number of colors to more than 24 bits (true color) via 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 when using a D-Sub analog signal, press the "AUTO" button on the remote control to automatically select the optimal screen status. If the adjustment is not satisfactory, select [PICTURE] - [Screen] - [Position], [Size] or [Phase] in the OSD menu. Also, verify that the video card resolution and frequency are supported by the product. If the frequency is out of range, set it to the recommended resolution in the Control Panel "Display" Setting menu. Ensure the proper input signal is connected to the signal port by using a matching signal cable.
