How to fix an LG 34UC88-B when nothing is displayed on the screen?
- TtoddtaylorJul 28, 2025
If nothing is displayed on your LG Monitor's screen, first ensure the power cord is correctly plugged into the outlet and that the power cable is properly connected. Press the power button. Also, verify that the correct input is enabled by going to Menu > Quick Settings > Input. If the monitor is in sleep mode, try moving the mouse or pressing a key on the keyboard. Confirm that your computer is turned on. If the signals from the PC are out of the monitor's frequency range, refer to the Product Specification section of this manual to set the appropriate frequency. Finally, check the cable and try reconnecting it.
