2.3 Digital Panel Connector (DVI-I)
The VGA card provides a DVI (Digital Visual Interface) connector
which allows you to connect an LCD monitor. The DVI connector
provides a high-speed digital interconnection between the computer
and its display device. To connect a LCD monitor, simply plug your
monitor cable into the DVI connector on the VGA card, and make
sure that the other end of the cable is properly connected to your
monitor. (refer to your monitor manual for more information)

*T.M.D.S. Technology
The graphics data sent to the digital monitor use Transition Minimized Differential Signaling
(T.M.D.S.)technology. TMDS uses an encoding algorithm to 8-bits of data into a 10-bit
transition minimixed, DC balanced character, which are transition-minimized to reduce EMI
with copper cables and DC-balanced for transmission over fiber optic cables. The TMDS
algorithm also provides robust clock recovery for greater skew tolerance with longer cables
or low cost short cables.
