In which situation can the computer system be the cause even when the monitor is powered on but blank?

Answer and explanation

Correct answer: The video cable is loose or the computer has not started

A monitor’s power light only shows that the display has electrical power; it does not prove that a video signal is arriving. A loose video cable, failed connection, or computer that has not completed startup can therefore leave the screen blank. A dirty mouse pad, empty printer, or low speaker volume does not affect the display signal. Thus, option A is correct.
