Gefen has released the
DVI Booster, a unit that helps you extend the length of a Digital Visual Interface (DVI) connection between your Mac and its display. Normally DVI connections are limited to about 15 feet because of video signal degradation. The DVI Booster corrects such degradation so you can extend out a DVI connection from 30 to 50 more feet, according to Gefen. The DVI Booster costs US$249.
