One of the most common uses for multi-monitor computers is Day Trading. That in itself is a big testament to how useful and productive you can be with multiple monitors. If the Wall Street big dogs are using them, you know it’s going to be an effective tool. In fact, using multiple monitors for stock trading is guaranteed to make you a better trader.
For Example: You can view charts on one screen and run your trading software on another. If you use more than two screens, you can watch your live news streams on a third monitor or perform internet research. You can also copy and paste across monitors, rather than maximizing and minimizing windows.
