Tripp Lite's P120-06N-ACT, Active DVI-D to VGA converter / adapter, allows you to utilize VGA display devices, such as monitors and projectors, when only a DVI-D Digital computer video port is available. No software or drivers are required...simply plug and play. For low-powered motherboard based DVI-D ports, a USB port and cable are provided to supply additional power to the adapter. Built in DVI cable pigtail negates the need for an additional DVI cable. Supports VGA cable distances up to 100ft.
