If the video resolution setting is higher than that supported by the display, the computer enters pan mode. In pan mode, the screen cannot be completely
displayed. For example, the taskbar that usually appears at the bottom of the desktop may no longer be visible. To view the rest of the screen, use the touch
pad to pan up, down, left, and right.
Extended Desktop Mode
NOTE: Use only the Dell-installed video drivers, which are designed to offer the best performance with your Dell-installed operating system.

monitor user's guide.
You can attach an external monitor or projector to your computer and use it as an extension of your display (known as dual independent display or extended
