As someone who has used both single monitor and dual monitor configurations, I was suspicious of his claim that having a single monitor increased productivity. But I tried to understand where he was coming from and I could see that having a second monitor could possibly cause more distractions. From checking e-mails to working on other tasks, the potential to slow down productivity is there. So I decided to run my own experiment.
For the majority of my day, I have two 22-inch monitors as my primary displays. They are configured to be in extended view and are not cloned. I turned off one of my two 22-inch monitors to see what kind of effects it might have. Instead of being hyper focused on what I had in front of me however, I ended up spending much more time than I’m comfortable with just switching from window to window to retrieve information.
Instead of just smoothly and easily finding my reference materials, I often had to fish for them among many open windows. While writing, I found myself having to constantly switch between my Internet browser and Microsoft Word to pull information from primary sources and my notes. It was adding seconds to the most ordinary of tasks. The time it took to write and edit documents increased, but yet I wasn’t finding any extra focus.
I am not alone in my doubt about the value of having one monitor over two. In a multi-screen productivity study conducted by Wichita State University and commissioned by Dell, participants were asked to gather different text and image elements in one working document from other documents and Web pages. Respondents stated that they found themselves perusing reference documents by roughly 4% less. And they overwhelmingly ranked dual monitors higher based on pleasantness to use. The most important piece from that study however, was that the participants were able to complete their task 2.42 seconds faster with a multiple monitor setup.
Another issue is that the picture included with the New York Times article shows Mr. Manjoo using quite a large primary monitor, with the secondary monitor turned off. From the looks of it, his display of choice seems to be a 27-inch monitor and with a resolution measuring 2560 × 1440. With so much screen real estate, I can easily see why a user wouldn’t need a secondary monitor.
At my personal workstation at home, I have been using dual Dell U2711 monitors, which are 27-inches diagonal and with a 2560 × 1440 resolution. With such a setup, I am able to open up to four Word documents side by side at 100% zoom. Even with just one 1440p monitor, I could effectively do what I would normally need two lower resolution monitors to do.
By using a display with such a large resolution, a user basically has two 1280 × 720 displays side by side. In fact, a 1440p monitor offers more real estate than two 720p monitors. So yes, one monitor can be just as effective as a dual monitor configuration—if that one monitor is a 27-inch 1440p display. For users with 1080p or smaller resolutions however, I contend that a dual monitor setup is a superior configuration.
But what do you think? Are you using one display or multiple displays?
