If your Dell monitor displays no video and the power LED is off, ensure the video cable connecting the monitor and the computer is properly connected and secure. Also, verify that the power outlet is functioning correctly by testing it with another electrical device. Make sure the power button is pressed and that the correct input source is selected via the Input Source menu.
