Add Multiple Displays to Your Notebook via a Single USB Port
With the help of the ViBook adapter
One of the nastiest things about notebook displays is the fact that they provide a rather limited space, compared to their wider counterparts, like PC monitors, for example. However, there are quite a few solutions out there that can be employed in order to overcome such a problem, and one of the simplest is the ViBook.
The ViBook is a graphics USB–DVI cable that allows users to connect more PC monitors to a single signal source, via a USB port. So, if your notebook sports a single free USB port, you can purchase a USB port, multiply the signal by four times, and then, by using four different ViBook units, hook up four monitors to the respective computer. Every monitor will act independently of each other, as a separate desktop, depending on the user's choice.
The device provides a very high level of versatility during use, since it supports any display up to a size of 22 inches and a resolution of up to 1680x1050 pixels wide or 1600x1200 pixels standard. It works with both DVI and VGA standards (using the supplied high quality DVI-VGA cable accessory), and is also accompanied by a dedicated driver for unattended installation in corporate environment.

One of the main advantages that come with the compact size of ViBook is the fact that it allows users to directly plug to DVI displays using the supplied custom made adapter. This way, adding the extra monitors will be done in no-time, thus making it a very good solution for installing presentation stands on the go, for example.
The ViBook is not the cheapest adapter one will find on the market, since it sells for somewhere around 130 US dollars, but if you're really in need of adding more desktop space to your computer in a very fast and easy manner, you should really give this thing a go.
