  If nothing is displayed on your LG monitor, there are several 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 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. * Make sure the computer is turned on. * Check the cable and reconnect it. * If signals from the PC are out of the monitor's frequency range, see the Product Specification section of this manual to set the appropriate frequency.

  If your LG monitor's screen display is unstable or shaky, and images leave shadow trails, it might be due to the resolution being set to HDMI 1080i 60/50 Hz (interlaced). Try changing the resolution to 1080P or the recommended resolution.
