A feature supported by some notebook computers that enables them to display images on an external monitor at a higher resolution than is supported by the built-in flat-panel display. For example, most flat-panel displays are limited to a maximum resolution of 800×600. With the virtual desktop feature, you could connect the computer to an external monitor and enjoy full SVGA (1,024×768) resolution.

Only part of the virtual desktop is displayed at any one time, but you can see hidden areas by scrolling the display. It’s as if the display screen is a small window overlaid upon a larger desktop.
