Mini DisplayPort connector

Mini DisplayPort shares its connector shape with Thunderbolt 1 and 2, but their functions are not identical.

Also called Mini DP mDP Mini DisplayPort Thunderbolt 1 port Thunderbolt 2 port

The same opening can hide different technologies.

Look for

Check both the small rectangular port shape and its documentation. An icon can be a useful clue, but the exact device specification remains the authority.

T04 · Document the actual path

Mini DisplayPort versus Thunderbolt

Mini DisplayPort shape alone cannot distinguish a Mini DisplayPort display path from Thunderbolt 1/2. Identify the exact port protocol and display type before choosing an adapter.

Read three exact-equipment examples →

What does the exact equipment documentation establish?

Unknown is a useful answer. Yes means you have the relevant model/port/product statement; it does not mean this site verified your equipment.

Read the model’s port table; record Mini DisplayPort or Thunderbolt instead of inferring protocol from shape.

Read the display model and input designation. A Thunderbolt display and a Mini DisplayPort display are different scopes.

Check the compatibility list. Apple’s cited Thunderbolt 3-to-2 adapter excludes DisplayPort/Mini DisplayPort displays despite the familiar shape.

Keep the adapter model’s operating-system/device support and display mode limits with the port evidence.

The next step is a specific documentation check.

  • Read the model’s port table; record Mini DisplayPort or Thunderbolt instead of inferring protocol from shape.
  • Read the display model and input designation. A Thunderbolt display and a Mini DisplayPort display are different scopes.
  • Check the compatibility list. Apple’s cited Thunderbolt 3-to-2 adapter excludes DisplayPort/Mini DisplayPort displays despite the familiar shape.
  • Keep the adapter model’s operating-system/device support and display mode limits with the port evidence.

Documentation declarations only; no physical test, negotiated mode, delivered power, safe mating, pinout or compatibility approval. 4 missing prerequisites; 0 recorded conflicts.

The useful distinction

Recognize it. Then verify it.

Mini DisplayPort shares its connector shape with Thunderbolt 1 and 2, but their functions are not identical. [C012A]

Apple’s Thunderbolt 3 to Thunderbolt 2 Adapter supports the documented Thunderbolt display path but excludes DisplayPort/Mini DisplayPort displays such as Apple LED Cinema Display, despite similar connector shape. [C012C]

TE's cited Mini DisplayPort receptacle is a 20-position connector example; the same physical form can appear in contexts whose protocol capability must be established from the exact device rather than shape alone. [C012B]

TE drawing C-2129320 D1 shows 2129320-3 as a reversed-offset Mini DisplayPort receptacle with four-row through-hole board termination; the mounting-side PCB layout is distinct from the mating face. [C012D]

Identify the documented form

Separate Mini DisplayPort shape from Thunderbolt capability.

  1. Mini DisplayPort shares a connector shape with Thunderbolt 1/2, so an outline match cannot select the protocol. S016

Before you connect

What to check

  1. Determine whether the port is Mini DisplayPort or an early Thunderbolt port.
  2. Do not assume a Mini DisplayPort source can operate a Thunderbolt accessory.
  3. For a display-only connection, verify the supported mode across the cable and devices.

Top row odd pins, bottom row even pins.

  • P012 Mini DisplayPort — **Agree** on the source side (VESA via B, NXP AN10873 via A) and the sink side (VESA via B, Wilder test adapter via A), including the lane reversal on the sink — B's VESA copy is from a third-party mirror (flagged in its JSON). B recorded that Dell's U2414H/U2415 sink tables contradict themselves, and followed VESA.
  • Applies to source devices (e.g., computer outputs).
  • Both Dell guides print the same table. It lists ML3(n) at both pins 3 and 5 and ML0(p) at both pins 10 and 12, which is internally impossible, and GND at 4 and 6. VESA Table 2-2 gives ML_Lane 3 (p) at 5, ML_Lane 0 (n) at 10, and CONFIG1/CONFIG2 (pulled down to ground) at 4/6. Rows follow VESA, and Dell is cited only where it agrees. The two Dell guides share one table, so they are not independent of each other.
  • Source-side rows rest on the VESA standard alone. No manufacturer source-device document (graphics card or computer) was obtained.
  • The VESA PDF came from a third-party mirror (glenwing.github.io), not from VESA. Its SHA-256 is recorded so it can be compared against a member copy.

V146 — Same outline does not mean the same adapter.

The source’s four-row description concerns PCB termination. Separately, Apple excludes Mini DisplayPort displays from its named Thunderbolt 3-to-2 adapter path despite the similar connector shape.
