The Gefen EXT-DVI-1CAT6 DVI Extender will send a single-link DVI video signal over just one Cat.6a cable at distances of up to 200 feet (60m) at 1920x1200@60Hz. Extension of DVI can now be simplified with the use of a single Cat.6a cable. Other solutions use at least 2 Cat.5/Cat.6 cables to accomplish this.
