The method of the present invention includes loading a selected set of preset parameters into a source device and a sink device of the DisplayPort device of an embedded system. Link training is then performed between the source device and the sink device utilizing the first set of preset parameter and the link status (bit lock, symbol lock and inter-lane alignment) of the DisplayPort device is then read. If the link status indicates that the link training is successful, a link is established between the source device and the sink device, or if the link status indicates that the link training is unsuccessful, a different set of preset parameters is loaded and link training is then performed again. The steps of loading, performing and reading are repeated with each of the plurality of sets of preset parameters until the link status indicates that the link training is successful.

Demultiplexed IHS video signal information is received by a video interface receiver, where it is used to generate an image on a digital display. Demultiplexed IHS bus information is received by a host bus interface transmitter / receiver, where it is used to support peripheral devices attached to the digital display.

A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI) or DisplayPort standards, and includes a raw cable and may include a boost device. The raw cable includes coaxial lines of a characteristic cable impedance higher than the impedance implied in the standards. The correct impedance is observed at the sending end by shunt resistors mounted in the first cable connector. The resultant loss of signal may be made up with the boost device mounted in the connector at the other end of the cable in the case of a long cable. Increasing the cable impedance reduces the inherent loss of the raw cable thus permitting the use of low cost material such as tinned wires. Similar advantages are obtained regardless whether Shielded Twisted Pairs (STP) or coaxial lines are used.
