  If no image appears on your LG Digital Signage, ensure the power cord is properly connected to the outlet. Also, check the signal cable between your PC and the product, and press the 'INPUT' menu on the remote to verify the input signal. If the signal from the PC is out of the product's frequency range, adjust it by referring to the Specifications in the manual, noting the maximum resolution for RGB, HDMI, DVI-D, and Display Port is 1920 x 1080 @ 60 Hz.

  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.
