Part of the amazing 3S Series of super space saving monitors, Hitachi's 813 Plus features the shortest depth available on any 21" monitor. The new Plus series of 21" monitors has the same technology as the previous award-winning 3S series, but adds high refresh rates, and additional features such as dual 15 pin D-subs so you can switch between 2 different computers without rebooting. Powerful performance, superior quality and amazing colors - this is why nothing comes closer to reality than a Hitachi monitor.
