And while you are there, check out the user ratings for Plugable USB graphics adapters from Amazon.com readers, averaging a full five stars.
One customer says, "The DisplayLink product line makes for expanding to additional displays a breeze."
Another says, "Quite impressed with this display adapter. I wanted to add a third 25" monitor to my system for video editing, works like a charm."
