Get extra distance out of your DVI signal with this DVI Booster from Gefen. Gefen's patented technology takes the DVI signal and corrects any transmission errors so that it can be sent up to 100 feet.

Simply plug this booster onto the end of your existing single-link DVI cable and get another 100 feet of extension, massively extending your effective DVI range. For those looking to go even further than 100 feet, just daisy chain multiple boosters together to increase your range.

The Gefen DVI Booster supports resolutions up to 1080p or 1920x1200 and distances up to 100 feet (with multiple boosters). Need extra cables? Check out our selection of DVI cables.
