  There are several possible reasons why your LG Monitor might not be displaying an image. First, ensure that the power cord is correctly plugged into the power outlet. Also, check that the signal cable between your PC and the monitor is securely connected. The issue could also be due to the signal from the PC (video card) being out of the vertical or horizontal frequency range of the product. If this is the case, adjust the frequency range by referring to the Specifications in this manual, noting that the maximum resolution is 1920 x 1080 (60 Hz). Finally, press the INPUT menu in the remote Control to check the input signal.

  Abnormal screen color on your LG Monitor can be due to several reasons. If the screen has poor color resolution (16 colors), 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. 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 is not a malfunction.

  If an after-image appears on your LG Digital Signage, and you've been using a fixed image for a long time, the pixels may be damaged. To prevent this, 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.
