  If the screen image on your LG Monitor looks abnormal, check if 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. Also, ensure that the proper input signal is connected to the signal port; connect the signal cable that matches with the source input signal.

What to do if after-image appears on the LG 22SM3B-B?

  Kendra DavisSep 13, 2025
  An after-image appearing on your LG Monitor can be due to using a fixed image for a long time, which may damage the pixels; use the screen-saver function to prevent this. Also, when a dark image is displayed on the screen after an image with high contrast (black and white or gray), this is normal for LCD screen products.
