I haven't gotten my new monitor yet, but why do some reviews complain that it doesn't include pivoting software? Is there a need for it? I thought this monitor was automatically capable to rotate between landscape and portrait.

What does software like Pivot Pro provide that isn't provided with the basic monitor that I will receive?

From the Pivot Pro Website:
