I first used a dual monitor set-up in a computer lab when I took a course in Visual Basic several years ago. Then I used two monitors while working for IT Training at BJU during grad school. I recently found a great deal on a LCD monitor and now I use two screens when I prepare sermons and Sunday School lessons. For a computer programmer or someone developing training materials, the second screen adds the benefit of seeing code & preview or application & training document at the same time. For Bible study, it lets you see your Bible software and your notes at the same time. I like to have Word open to type my notes on my laptop screen and BibleWorks or Logos open on my second monitor right next to that. 

Set-up is pretty simple – just plug the second monitor into the power source and connect it to your laptop’s VGA output (the same one you’d use to connect to a projector). Then (for Windows XP users), right-click your desktop, click “Properties” in the dialog box, and go to the “Settings” tab. (In Vista, right-click the desktop, choose “Personalize,” then “Display Settings.”)  Drag the boxes around to match the placement of your two screen, make sure they’re both active (if number 2 is grayed-out, right-click it and choose “Attached”). Then choose the screen resolution that works best for your secondary monitor – you’ll probably have to try a couple options to find the one you like best. Open one of your softwares but do not maximize it. Drag it over to the second screen. Now you can see your notes and your Bible / commentary at the same time. 

If you’re looking for a cheap flat monitor to use as a second screen, I found the best price at accurateit.com – I got a slightly used 17″ monitor for less than $70. Of course, their prices change regularly, so watch for a week (or use www.pricewatch.com to find low prices). Their “grade B” monitors come slightly used and without a desk-stand, but they’re very well-priced. I found that I can balance my monitor on my desk (leaning against a shelf) and use it well. For the more mechanically-advantaged, you can cut a couple brackets out of angle-iron, drill holes at 25mm intervals and get some M8 screws and make your own stand/shelf clamp. If you’ve got a better idea for a home-made stand, I’d love to hear it!
