In case you thought people who ask for and use multiple monitors are just being silly, there is now research which shows what I have known for many years. More monitor real estate means more productivity.
In fact two 20-inch monitors yields a 44% increase over a single 18-inch monitor. A single 24-inch monitor yields a 52% increase in productivity over that same "puny" 18-inch monitor.
A 26-inch monitor actually reduced productivity over the 24 incher.
What does all this tell us? Choose the monitor size your employees use very carefully… A one-size-fits-all approach does not apply to monitors — or computers for that matter.
Disclosure: multiple monitors of multiple sizes were used in the creation of this blog entry.
