replaced by EXT-DVI-1CAT5-SR The Gefen DVI Over 1 CAT6 Extender will send a single-link DVI video signal over just one (1) 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 CAT5/CAT6 cables to accomplish this. The Gefen DVI Over 1 CAT6 Extender fully supports all of the DVI specification for true compatibility with DVI devices. The Extender's pure digital transmission method insures 100% signal integrity over this single cable extension solution.
