What Is a Monitor? Define
A monitor is a piece of computer hardware that displays the video and graphics information generated by a connected computer through the computer's video card.
Monitors are similar to TVs but usually display information at a much higher resolution. Also unlike televisions, monitors typically sit atop a desk rather than being mounted on a wall. A monitor is sometimes referred to as a screen, display, video display, video display terminal, video display unit, or video screen.
