Most of us are multi-tasking by using at least two of the following applications at the same time - word processor, spreadsheet, email or web browser. Using a single monitor to work means that every time you need to view a different document you have to go looking for it. Getting from one application window to another requires finding the right task bar or spend time Alt-Tab.

Using dual monitors makes many computing tasks easier by allowing you two full screen views. When you use two monitors, Windows spreads your desktop across the monitors and each application can have its own full screen display. With dual monitors you can have instant access and view to what you need. This also allows you to avoid the clutter of having too many windows or programs opened at once.
