Gefen today announced two new dual link DVI products that work with high definition video transmitted through dual link DVI, which uses all 24 pins of the connector to send video at resolutions up to 3840 x 2400 at 60Hz. The DVI-DL Switcher (US$699) allows you to connect two sources to a display equipped with just one input, while the DVI-2000 HD ($1399) uses a sender and receiver system to send dual link DVI video up to 1640 feet (500 meters) over fiber optic cables.
