CLASSIFICATION: Display cables and adapters. Identify protocol, direction, pinout and exact cable revision before connection.

Interface and capability

Standard / protocolVESA DisplayPort 2.1 UHBR20. Connector appearance alone does not establish compatibility.
Endpoint / pinoutFull-size 20-pin connector: four main lanes plus AUX and HPD; UHBR20 is link signaling, not a display mode.
Capability / limits20 Gbit/s per lane raw / 80 Gbit/s aggregate before encoding overhead; DP40/DP80 qualification and supported length apply to exact cable.
Certification / lengthStandards define interface requirements, not every assembly’s performance. Certification, mode, current/power rating, direction and maximum length belong to the exact product/revision and complete channel; verify its manufacturer specification. Do not infer certification from connector shape or marketing terminology.

Compatibility & handling

  • Check VESA-certified label, source/sink support, DSC and mode. Avoid unqualified extensions; obey the product bend radius.
  • Inspect connector keying, latch, contact condition, shielding, jacket and model/revision marking. Stop if contacts are bent, loose, scorched, corroded or mismatched.
  • Route without tension or sharp bends; follow product bend-radius, strain-relief, current and environmental limits. Test at the intended protocol and mode—physical fit is not a compatibility test.
