Information sent over a digital DVI cable
HDMI supports the transfer of digital information only. Using a dual link cable when possible will increase the speed of the information transfer and produce an increased signal quality. Information sent over a digital DVI cable is sent using a format called Transition Minimized Differential Signaling The only different between a single-link cable and a dual-link cable is the single-link cable has one TDMS transmitter, while the dual-link has two. DVI is also one of the few interfaces found on most of the high-end hd cable televisions available today on the market. Today, with the advancement of display technologies, DVI can now be found on the majority of graphics cards, as this is the preferred method for hooking up an LCD monitor because of the difference in signal quality DVI has over VGA.
