The DisplayPort to DVI-D (Dual-Link) Adapter actively converts the output signal from a DisplayPort video source for use with a DVI-D display (monitor, etc.) or projector, helping to eliminate the equipment costs of upgrading a DVI display to a newer model for the sake of compatibility.

The adapter supports high resolution video (up to 2560x1600 at 60Hz), maintaining the graphical performance from a DisplayPort-equipped desktop video card, laptop or MacBook .

The adapter performs an active DisplayPort-DVI conversion that is suitable for video sources that output either multimode (DP++) or single-mode DisplayPort signals. This ensures the adapter can be used even with graphics cards that aren't capable of outputting multimode DP++ signals, such as ATI Eyefinity cards.

Works with DisplayPort Video Cards such as ATI Radeon HD Eyefinity Graphics Cards.
