The connector for the digital video monitor is a standard digital-only DVI connector. Figure 3-4 shows the contact configuration and Table 3-4 lists the signal assignments.
The graphics data sent to the digital monitor use transition minimized differential signaling (TMDS). TMDS uses an encoding algorithm to convert bytes of graphics data into characters that 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.
For information about TMDS, see the specification, Digital Visual Interface DVI Revision 1.0, available on the web site of the Digital Display Working Group (DDWG) at
