A host of studies by specialists in human-computer interaction suggest that combining two displays, or using a single huge monitor, can significantly enhance your productivity. The theory is simply that the bigger your monitor, the more of your work you’ll be able to see and the more you’ll be moved to do.
In a study commissioned by the electronics company NEC, researchers at the University of Utah recently asked office workers to perform several common tasks using various monitor configurations. They found that people who used two 20-inch monitors were 44 percent more productive at certain text-editing operations than people using a single 18-inch monitor.
