Chapter 4. Using the video function of the USB Port
Replicator
This section provides information about the video function of the USB Port Replicator.
Video Modes
The USB Port Replicator video output works in two modes:
v Extended
v Mirror
By default, the USB Port Replicator uses video output in Extended mode.
Extended mode
The Extended mode enables you to split your display across multiple monitors. You can drag and drop
windows from one screen to the other. With this mode you can increase your productivity by performing
the following actions:
v Read e-mail on one display and open attachments on the other.
v Expand a spreadsheet across both monitors.
v For graphics editing, increase your working area by placing all the pallets and toolbars on the second
display.
v Keep your desktop on the external monitor and watch a DVD on your notebook computer screen.
Mirror mode
The Mirror mode clones from your notebook computer screen to the external monitor. The USB Port
Replicator automatically selects the settings (screen resolution, color quality, and refresh rate) for the
external monitor that will enable the best resolution based on your notebook computer settings.
Switching video modes with the Dual View button
To switch between the Extended and the Mirror mode, press the Dual View button on the front of your
USB Port Replicator. When your USB Port Replicator is in the Mirror mode, the Display Mode Indicator
glows green. When your USB Port Replicator is in the Extended mode, the Display Mode Indicator
glows green. It takes a few seconds to change from the Extended mode to the Mirror mode or from
the Mirror mode to the Extended mode. During the transition, the indicators
and
will
alternatively turn on and off until the USB Port Replicator configures the selected mode to your system.
Wait until the change is complete to modify the video settings of the USB Port Replicator again.
To deactivate the video output of the USB Port Replicator, press and hold the Dual View button for more
than three seconds. The external monitor will become blank and any open window on the external
monitor will move to the notebook computer. When the video output of the USB Port Replicator is
deactivated, both the Display Mode Indicators are turned off. When you press the button again, the
display returns to the last mode you were in. However, applications previously opened in the external
monitor are not moved back to the external monitor from your notebook computer.
