Standard configuration (add up to two displays; Windows XP / 2000)
Extended configuration (add three displays; Windows XP only*)
*Most Windows 2000 notebooks cannot address the #2 external monitor as an independent display, but can
use the #2 external monitor as a mirror (clone) of the notebook display. In this case, there are three external
displays, with the #2 display mirroring the notebook LCD (which can often be turned off or closed).
