  If nothing is displayed on your LG Monitor, here are a few things to check: * Ensure the power cord is correctly plugged into the power outlet. * Verify the power cable connection and press the power button. * Confirm that the connected input is enabled by going to Menu > Quick Settings > Input. * If the monitor is in sleep mode, move the mouse or press any key on the keyboard. Also, check if the computer is turned on. * Make sure the signals transferred from the PC (graphics card) are within the horizontal or vertical frequency range of the monitor. Refer to the Product Specification section of this manual to set the appropriate frequency. * Inspect the cable and try reconnecting it.

Why does the display color look abnormal on my LG 34UM61 Monitor?
- R
  Robert WhitneyAug 8, 2025
  If the display color on your LG Monitor appears abnormal: 1. Set the color to 24 bit (true color) or higher. In Windows, this can be found at Control Panel > Display > Settings > Color Quality. 2. Check the signal cable to ensure it's properly connected. Reconnect the cable or reinsert the PC's graphics card. Note that when using the monitor, pixilated spots (red, green, blue, white, or black) may appear on the screen. This is normal for an LCD screen and does not indicate an error or affect the monitor's performance.
