PS/2 form versus S-Video form

Compare the contact pattern and keying, not only a circular shell.

Computer-generated illustration, not a photograph. — P108 · Connector6-pin Mini-DIN (PS/2 form)

How they differ

6-pin Mini-DIN (PS/2 form) Count the nominal six contact positions and compare the key block with the manufacturer illustration.
4-pin Mini-DIN (S-Video form) Compare four positions arranged in two rows and the key block. This record does not cover every proprietary multi-pin video socket.

Mini-DIN PS/2 vs S-Video

Side by side source-bounded representations of 6-pin Mini-DIN (PS/2 form) and 4-pin Mini-DIN (S-Video form). Left: Six-position keyed Mini-DIN PS/2 form. Right: Four-position keyed Mini-DIN S-Video form. No pinout, matching size or mating approval. — Cable-end plug concept with separate number tokens; no socket-side pin array. Number of positions appears as a label; the relative pin layout is deliberately omitted. No size comparison or pinout.

Verify before choosing

A circular shell does not identify keyboard, mouse or video service. Never force a similarly shaped plug.

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.DVI-D single-link vs DVI-D dual-linkBoth are DVI-D forms, but their contact patterns differ. Inspect the complete pin field instead of relying on the DVI label alone.HDMI connector vs HDMI 2.1HDMI Type-A describes a connector form; HDMI 2.1 describes a technology family. The connector shape alone cannot establish the implemented HDMI feature set.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.
