Most of today's graphics cards offer two display outputs, letting you connect a pair of displays. We challenge you: try working across two screens and then go back to one cramped LCD. It isn't fun. All of that desktop real estate gets to be addicting after a while, and anything less just feels cramped.
Multi-Monitor On The Road?
In this regard, notebook and netbook (especially) owners are disadvantaged. Many notebooks include the ability to attach a second display via VGA, DVI, or HDMI connectivity. But netbooks don't sport that sort of functionality. Nevertheless, as more and more people buy netbooks and try forcing them into productivity roles, attempting to replace larger notebooks, the ability to add another display would be particularly useful, even if only for sending/receiving email, surfing the Internet, or word processing.
USB Graphics Extenders
Owners of netbooks can solve this problem by using an external USB graphics extender, which connects to the monitor via USB port. This kind of connection is ideal for the folks that only have one or no graphics output at all--for instance, low-profile enclosuress. Also this solution enables more than one external monitor to be attached to notebooks, which can also come in useful. In this article, we are taking a look at one such USB graphics extender from Village Tronic, called the ViBook.
