Quizplus · Accepted Answer

Turning off the screen when not in use is an energy-efficient measure as it saves electricity. Using a screen saver, on the other hand, does not save power and might even consume extra power as the computer tries to run the animation. Also, turning off the screen when not in use helps to prolong the life of a display device since it reduces the amount of time the screen is active, which reduces the wear on the display components. Therefore, both options are the best choice to save energy and prolong the life of the screen.
