Chapter 4. Working with the dock
This section provides information about the video output modes of the dock and instructions on how to
configure the dock to your needs.
Understanding the video output modes
The dock works in the following three video output modes:
• “Extend mode” on page 9
• “Mirror mode” on page 10
• “Single-display mode” on page 10
By default, the dock works in the extend mode. The first time you connect the dock to your computer,
the resolution of your computer and the connected monitor is changed to the default. You can configure
your resolution to your needs.
Extend mode
When the dock is in the extend mode, it splits your display across two monitors. Your computer monitor
becomes the primary display and the external monitor becomes the secondary display. By default, the
external monitor display is on the right side of the computer monitor display.
In extend mode, you can drag and drop windows from one display to the other. You also can increase
your productivity by doing the following:
• Reading e-mails on one display and opening the attachments on the other
• Expanding a spreadsheet across two displays
• Increasing your work area by putting all the palette and toolbars on the other display when you are
doing graphics editing
• Keeping the desktop on one display and watching videos on the other
