Chapter 4. Working with the Lenovo USB Port Replicator with
Digital Video
The chapter provides information about the video output function of the port replicator and instructions
on how to work with the Lenovo USB Port Replicator with Digital Video utility, which enables you to
configure the port replicator to your needs.
Understanding the video output modes
The port replicator works in two video output modes:
v Extend mode
v Mirror mode
By default, the port replicator uses the Extend mode to output the video.
Extend mode
The Extend mode splits your display across multiple monitors. There are two options when using the
Extend mode:
v System - Primary: In this mode, your notebook computer monitor will be the primary display and the
external monitor will be the secondary display.
v Second Display - Primary: In this mode, the external monitor will be the primary display and the
notebook computer monitor will be the secondary display.
In the Extend mode, you can drag and drop windows from one display to the other. Also, you can
increase your productivity by doing the following:
v Read e-mails on one display and open the attachments on the other.
v Expand a spreadsheet across both displays.
v For graphics editing, increase your work area by putting all the palette and toolbars on the second
display.
v Keep the desktop on one display and watch a DVD on the other.
