Multiple Display Productivity

It seems that when I travel to offices these days, it's standard for most desk setups to have two monitors. I think all the desks at Redgate have a docking station and two monitors for people to use. They also convert to standing desks, which is handy. I have a standing desk that I use regularly, and it's nice to have that option when I visit an office. At a number of customer sites, I've seen similar setups, sometimes with laptop/monitor lifts instead of desks that rise. Recently I saw a docking station announced that can support four monitors. I wonder how many of you want, need, or use more than two monitors. While there is often a standard in offices, since many of us work part or full-time at home, perhaps you have a different setup. Maybe you have one or two large monitors instead of 3 or 4 smaller ones. I'd certainly be interested to know if any of you have more than 4 monitors. Read the rest of Multiple Display Productivity
