The DVIGear High Resolution DisplayPort copper cables transport DisplayPort signals at bit rates of up to 21.6Gbps over lengths of up to over 15m, with support for uncompressed DisplayPort resolutions up to 4096x2160/60Hz.
Copper cables carrying high resolution DisplayPort cables over long distances must overcome several challenges, such as insertion loss, differential skew and jitter. Insertion loss is caused by cable capacitance acting as a low-pass filter, blocking higher frequency signal components. Skew occurs when differential DisplayPort signals get delayed and become out of phase when passing over a lang cable.
Both factors increase digital jitter, which worsens with higher resolutions, higher bit rates and longer cable distances.
