DVI provide one TMDS clock pair and 3 TMDS data pairs in single link mode or 6 TMDS data pairs in dual link mode. TMDS data pairs operate at a gross bit rate that is 10 times the frequency of the TMDS clock. In each TMDS clock period there is a 10-bit symbol per TMDS data pair representing 8-bits of pixel color.
A third party connector adapter, previously available in Japan, buffers and splits only the TMDS sync signal. Internal dual-link retrofits included an unbuffered hardwire jumper-split of the TMDS sync signal which resulted in impedance mismatch, and an unbuffered hardwire split of the TMDS sync signal with a 24 Ohm series resistor on each leg.
Schematic of a TMDS link used as a link for digital component video data (RGB) between a video controller (PC) and a display controller (Monitor) in interfaces such as DVI or HDMI Transition-minimized differential signaling ( TMDS ) is a technology for transmitting high-speed serial data used by the DVI [ 1 ] and HDMI video interfaces, as well ...
It is electrically compatible with dual-link DVI-D, but as of August 2021 has not yet been used in any products. [citation needed] With the introduction of HDMI 1.3, the maximum bandwidth of single-link HDMI exceeded that of dual-link DVI-D. As of HDMI 1.4, the pixel clock rate crossover frequency from single to dual-link has not been defined.

P&D combined analog and digital video with data over USB and FireWire to reduce cable clutter, but the feature creep resulted in an unpopular, expensive connector. [2]: 4 Compaq described DFP as a "transition" step between the analog VGA connector and P&D: DFP was designed by a consortium including Compaq, Hewlett-Packard, and ATI Technologies as a smaller, simpler connector, dropping support ...
