Working late? Blame your computer screen. A new study finds that bigger monitors make people more productive.
Researchers at the University of Utah tested how quickly people performed tasks such as editing a document and copying numbers between spreadsheets while using different computer configurations: one with an 18- inch monitor, one with a 24-inch monitor and one with two 20-inch monitors. Their finding: People using the 24-inch screen completed the tasks 52% faster than people who used the I8-inch monitor; people who used the two 20-inch monitors were 44% faster than those with the I8-inch screens.
The study concluded that someone using a larger monitor could save 2.5 hours a day. But James Anderson, the professor in charge of the study, said to take that result with a grain of salt: It assumes that someone will work nonstop for eight hours, which no one will, and that the tasks they perform will benefit from a larger screen, which isn't always the case. Still, tasks such as moving data between files are ideally suited to bigger or multiple screens. Mr. Anderson, who uses a computer with two 20- inch screens and one 24- inch screen, recommends that businesses take the time to match employees with the proper screen size based on job requirements.
A caveat: The study was funded by NEC Corp., which makes computer monitors. Mr. Anderson said it was vetted by his university's research board.
