The UltraAV DisplayPort to DVI Dual-Link adapter enables the connection of your DisplayPort supported computer to a DVI Dual-Link supported television, monitor or projector. Simply connect the DisplayPort (male) end of the connector to your computer and plug your existing DVI Dual Link cable from the display into the DVI (female) adapter. Now plug in the USB connector to your computer's USB port. Setup is complete, there is no software to install. The circuitry built into the adapter seamlessly uses the power from the computer's USB port for all of its power needs.
