DVI Connector: DVI1 (Digital Output Only, optional)
The mainboard 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.

*T.M.D.S. Technology
The graphics data sent to the digital monitor use Transition Minimized
Differential Signalling (T.M.D.S.) technology. TMDS uses an encoding
algorithm to 8-bit of data into a 10-bit transition minimized, 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.
- No analog output in this model.
