Extend Your Desktop to Another Display

Extends the primary desktop to the display currently selected. Requires at least 2 displays.

Overview

Extend your work surface or display to another monitor to display them on a combined, single extended desktop.  This allows each monitor to display different things. Extended mode is often used when using PowerPoint so that a presenter can see their notes on one monitor and the presentation on another display.
