HDMI connector vs HDMI 2.1

HDMI Type-A describes a connector form; HDMI 2.1 describes a technology family. The connector shape alone cannot establish the implemented HDMI feature set.

How they differ

HDMI Type-A Look for a wide keyed connector with angled lower edges. Distinguish it from DisplayPort, whose silhouette has a different corner treatment.
HDMI 2.1 overview Read the port’s feature list and supported display timings. Treat cable category, adapter capabilities and endpoint support as distinct evidence requirements.

Full evidence ledger and sources ↓

Illustrations are computer-generated with prior AI visual review; independent technical and rights review pending. A comparison is not a compatibility verdict.

This page deliberately crosses evidence layers.

Read the Layer row before comparing any numeric field. A connector form cannot inherit the maximums of a technology merely because that technology can use the connector.

Families represented: Video

Different layers, not interchangeable alternatives.

This selection mixes connector shapes, standards or cable classes. Numbers from a technology specification cannot be assigned to a connector merely because it uses that shape.

HDMI Type-A vs DisplayPort connectorHDMI and DisplayPort are different connector families. Choose the physical form first, then verify the device capabilities and direction separately.HDMI Type-A vs Mini HDMI vs Micro HDMIAll three belong to HDMI but use different physical connector forms. Identify Type A, Type C or Type D before selecting the cable ends.DisplayPort 2.1 vs HDMI 2.1The useful comparison is the implemented feature set of your devices, not the family maximum.DisplayPort connector vs DisplayPort 2.1The full-size DisplayPort connector does not identify the implemented DisplayPort generation, link rate or optional features.DisplayPort vs Mini DisplayPortFull-size DisplayPort and Mini DisplayPort are different physical forms. Mini DisplayPort shape also appeared on Thunderbolt 1/2 products, so function still needs device evidence.DVI-D dual-link vs DVI-I dual-linkDVI-D and DVI-I use related shells but have different contact arrangements. The analog-contact area is a key physical distinction.

Trace 11 claims to their source records

C008A · P008

The familiar full-size HDMI connector is Type-A; Mini and Micro HDMI use different physical forms.

Claim scope: Consumer identification / documented standard or product class only

Source links: S018 · Evidence trail → (private workspace)

C008B · P008

HDMI version labeling alone does not identify every optional feature implemented by a product.

Claim scope: Narrowly stated supporting distinction; not an end-to-end device guarantee

Source links: S012 · Evidence trail → (private workspace)

C008C · P008

TE's cited Standard HDMI receptacle is a 19-position connector example, supporting a 19-contact engineering count for the full-size HDMI form without implying HDMI version or video capability.

Claim scope: Connector-form contact count supported by one manufacturer example; protocol/version capability explicitly excluded.

Source links: S365 · Evidence trail → (private workspace)

C008D · P008

Elgato 4K X has one HDMI input for an unencrypted video source and one HDMI passthrough output to a display; captured video reaches a computer through a separate USB-C connection.

Claim scope: 4K X only; input/output direction must not be exchanged and the selected profile is not a full connector inventory.

Source links: S450 · S451 · Evidence trail → (private workspace)

C008E · P008

Elgato separates supported 4K X HDMI passthrough signals from capture formats. Its detailed guidance says DSC video cannot be captured even when a passthrough image is visible.

Claim scope: DSC limitation and mode-selection boundary, not a diagnosis of every black capture frame or a universal HDMI limit.

Source links: S452 · Evidence trail → (private workspace)

C008F · P008

The ATEM Mini Pro ISO specifies four HDMI Type A inputs and one HDMI program output; the separately listed total of two outputs is not a count of HDMI output sockets.

Claim scope: Exact Pro ISO Connections table and labeled panel diagram; not a sibling model’s connection count.

Source links: S453 · Evidence trail → (private workspace)

C008G · P008

The ATEM Mini Pro ISO Standards table lists no Ultra HD video standards. Its description of finishing in Ultra HD via relinked media does not establish an Ultra HD HDMI input or output mode.

Claim scope: Pro ISO live video-interface standards versus post-production description; no new conversion or capture capability inferred.

Source links: S453 · Evidence trail → (private workspace)

C008H · P008

HDMI Cable Power requires support from both the active cable and the HDMI source. HDMI LA specifies source/sink direction for active cables and a separate power connector for sources without Cable Power support.

Claim scope: HDMI Cable Power feature scope; follow the exact cable’s instructions. Not monitor power or a universal converter-power rule.

C008I · P008

TE drawing C-1747981 H maps 1747981-1 to a without-flange HDMI board-receptacle form and presents its mating face separately from the reference PCB layout.
