Most folks have probably already figured out for themselves that having to
use a painfully small display with a low resolution impedes their productivity.
However, according to the Wall Street Journal's Business Technology Blog,
a study conducted by researchers at the University of Utah suggests that
even switching from a normal-sized display to a larger one-or two larger
ones-has a significant effect, as well. According to the researchers' findings,
folks who use a single 24" display are 52% quicker at tasks like editing
documents and tossing numbers between spreadsheets than those who use a single
18" display. Having two monitors instead of one helps, too, although not quite
as much: the speed increase from switching to dual 20" displays from a single
18" monitor is only 44%. Interestingly, the researchers say productivity
actually goes down when users switch to a 26" monitor, suggesting 24" could well
be the sweet spot.
Yeah! The more, the merrier :-) Personally, I use a single 22" widescreen monitor.
