The USB to DVI Graphics Adapter allows you to use your computer’s USB port to connect extra monitors. The extra monitors can be configured to either mirror your primary screen or extend the Windows desktop, allowing visibility of more applications.

This ensures that there is little difference in performance between a directly connected screen and a screen connected through the USB port.
