Which Monitor Setup is Most Productive?

What kind of monitor setups are most productive? This is a question that I ask myself often, as I try to be most productive at my school work, which is more often these days completed on computers.

A study by The University of Utah has concluded that two monitors can significantly increase efficiency. Further, monitors of size 24" tend to be the most productive.

So if I’m interpreting this correctly, two 20" or 24" monitors will achieve the optimal efficiency for me.

Dr. James Anderson discussed his findings in his paper (begins on pg. 32) as well as on NPR. Very interesting.
