In my mind, there’s no question that any information worker will be more productive with two monitors than with just one. I’ve been using dual monitors for at least five years, and I can see my productivity drop when I try to work with just one, as I do when traveling with a notebook.
I’ve considered adding a third monitor, but it’s never made it to the top of my upgrade stack. Partly, that’s because I’m not sure I’d really get a lot more benefit out of it. Some time back, Jeff Atwood argued that three monitors is the "sweet spot" in terms of desktop space, pointing out that Google’s Larry Page and Microsoft’s Bill Gates both use triple-monitor setups. Today, Scott Mitchell says he doesn’t see the payoff:
I’ve been using the three monitor setup for a couple of months now and regret to say that I have not seen the same productivity benefits or improvement of worklife that Jeff espouses or that I enjoyed when going from one monitor to two. For certain tasks I am more productive with three monitors than two, a prime example being if I need to review a client’s email while bug bashing. I can have the email open that explains the error in one window, Visual Studio in another, and the web application running in the third. However, for most other activities the third monitor does not add too much value. Consequently, it’s not uncommon for one of the three to sit unused for long stretches of time.
In my hardware setup, the biggest issue is how to drive that third monitor. Currently, I have a 24-inch (1900×1200) widescreen LCD and a 4:3 (1600×1200) LCD. Because both displays are the same height, they form a continuous desktop surface. I keep the Windows Vista Sidebar and the Taskbar on the smaller of the two monitors, arranged on the right. The widescreen monitor is on the left, and I use Ultramon’s extra taskbar to manage windows on that display. Here’s a bird’s-eye view:
Jeff Atwood uses a Matrox TripleHead2Go device to drive his three monitors. [Update: In the comments, Jeff clarifies that no, he doesn’t use this device. Instead, he has a pair of PCIe video cards.] As he points out, though, this device is less than optimal because it creates a single large display instead of three individual displays. For me, the dealbreaker is that it requires all three monitors to be the same resolution, and the maximum supported resolution for each screen in a three-monitor display is 1360×768. (The digital edition will handle two 1900×1200 displays, but that won’t help me.)
The more logical way for me to get a third monitor is to add a second video card. Alas, none of my desktop systems have two PCIe x16 slots. I’ve looked into using PCIe x1 slots and PCI slots, buut the performance is terrible and the price is high for those options. For my next desktop PC I’ll probably spec out a gaming-class machine that has two video card slots.
Meanwhile, I’m happy and productive with two monitors, and I guess it will stay that way for a while.
Update: I love my readers.
In the comments, James Tenniswood suggests a USB-to-DVI external adapter, which can drive an LCD monitor at 1280×1024 ($110, free shipping), or a high-resolution USB-to-DVI adapter that works at 1600×1200 ($130 with free shipping).
Reader Jeremy (no last name) swears by MaxiVista and says he “experienced a great lack in productivity” when he had to go back to two monitors after using three.
From Italy, Paperino says he is using an EVGA USB adapter with good results. Customer reviews at Newegg are mixed.
Any other options worth exploring?
