  If nothing is displayed on your LG Monitor, ensure the power cord is correctly plugged into the power outlet and that the power cable is properly connected. Press the power button. Also, verify that the connected input is enabled in the monitor's menu (Menu > Quick Settings > Input). If the monitor is in sleep mode, move the mouse or press any key. Check if your computer is turned on. If the signals transferred from the PC are out of range, refer to the Product Specification section of this manual to set the appropriate frequency. Finally, check the signal cable between the PC and the monitor and reconnect it if necessary.

Why is the display color abnormal on my LG 29UC88-B Monitor?
- B
  Bryan MackAug 19, 2025
  If the display color on your LG monitor is abnormal, first, set the color to 24 bit (true color) or higher by navigating to Control Panel > Display > Settings > Color Quality in Windows. Then, check if the signal cable is connected properly; reconnect the cable or reinsert the PC's graphics card. Note that pixilated spots (red, green, blue, white, or black) may appear on the screen during monitor use; this is normal for an LCD screen and not an error.
