http://realestateappraisertips.info/ - Real Estate Appraiser Tips On Using Dual and Dual Vertical Monitors
In the photo below, I have two (2) 19 Inch Dell Monitors. For the right monitor, I positioned it vertically so that I can see almost a whole page of an appraisal at a time. The benefits are that I can see more of the appraisal page and there is less scrolling needed. By being able to see one page of an appraisal at a time, I can a whole page of home photos, a whole map page at a time, a whole page of additional comments at a time, and makes it possible to see two to three half or 1/3 pages at a time. I am loving this new setup because of how much more productive it's allowing me to become. I also placed a roll of duct tape below the right monitor, which raised it slightly and so it's totally stable now and won't move or fall at a slight tilt.
The Appraisal Software in the photo is SFREP's Appraise-It, which I have been using since 1991.

Back when i was a daytrader i had a multi monitor set up. It looked pretty cool but everyone thought it looked crazy with 4 monitors around the keyboard.
