You can use this DVI Dual Link cable to connect a computer with a DVI output to a TV, monitor, or projector with a DVI input. Suitable for resolutions up to 2560 x 1600 @ 60 Hz (WQXGA) or 3840 x 2400 @ 30 Hz (WQUXGA). A DVI cable only transmits images. With Dual Link, two parallel connections are made, doubling the bandwidth. With a dual link, a higher resolution can be achieved than with a single link.
