How to fix an LG 34BK95U when nothing is displayed on the screen?
- PPhilip KimJul 29, 2025
If nothing appears on your LG Monitor screen, first, ensure the power cord is securely plugged into the outlet. Then, check the power cable connection and press the power button. Next, verify that the correct input is enabled in the monitor's Settings under the Input section. Also, inspect the cable and reconnect it. If the issue persists, for HDMI Input, disable HDMI ULTRA HD Deep Color in the monitor's General settings. For DisplayPort Input, match the DisplayPort Version in the monitor's General settings to the connected device. Refer to the Product Specification section of this manual for the appropriate frequency settings. For PCs supporting only USB-C output, use a USB-C Cable (sold separately). Finally, confirm with your PC manufacturer whether your PC supports ThunderboltTM 3.
