Dual monitor
Updated: 04/02/2019 by Computer Hope
Some computers allow for a dual monitor setup, which is where two monitors are connected to the same computer simultaneously. The ability to connect two monitors requires a video card with two ports for video out, such as VGA, HDMI, DVI or DisplayPort, on it.
Having dual monitors allows for split screen, which is typical in an office setting where users need to have multiple windows displayed at the same time. For example, a web designer may need to have Dreamweaver and Photoshop open at the same time.
