A method for tunning high speed link parameters for cables with a transceiver at each end includes transmitting, in response to establishing a link, an eye pattern bit sequence from a first computing device to a second computing device over a cable with a transceiver connected to each end of the cable. Establishing the link includes establishing a communication link over the cable between the first computing device and the second computing device. The method includes receiving an eye pattern quality message from the second computing device using a device discovery protocol. The eye pattern quality message includes quality information of a received waveform corresponding to the transmitted eye pattern bit sequence. The method includes adjusting transmission parameters for transmission over the cable in response to the quality information, and retransmitting the eye pattern bit sequence using the adjusted transmission parameters.
