The Different Types of HDMI Connectors
HDMI (High-Definition Multimedia Interface) has become the global standard for transmitting high-quality digital video and audio between devices. From consumer electronics to industrial and automotive applications, HDMI offers a reliable, high-bandwidth solution that supports resolutions from Full HD through to 8K and beyond.
However, not all HDMI connectors are the same. There are several types of HDMI interfaces, each designed for specific use cases. Choosing the correct HDMI type is crucial to ensure compatibility, performance, and durability—especially in professional and embedded computing environments.
HDMI Types A, B, C, D & E
HDMI Type A (Standard HDMI)
- Pins: 19
- Usage: The most common HDMI connector, used in TVs, monitors, desktop PCs, gaming consoles, and media players.
- Features: Supports all HDMI standards and resolutions, up to 8K with HDMI 2.1.
HDMI Type B (Dual-Link HDMI)
- Pins: 29
- Usage: Designed for very high-resolution video, though rarely adopted due to the advancement of HDMI 2.0/2.1.
- Features: Dual TMDS link for higher bandwidth, largely replaced by updated standards.
HDMI Type C (Mini HDMI)
- Pins: 19
- Usage: Found in smaller devices such as tablets, DSLR cameras, and camcorders.
- Features: Same functionality as Type A in a compact form factor.
HDMI Type D (Micro HDMI)
- Pins: 19
- Usage: Even smaller than Mini HDMI, used in ultrabooks, smartphones, and compact portable devices.
- Features: Maintains full HDMI capability in the smallest connector size.
HDMI Type E (Automotive HDMI)
- Pins: 20
- Usage: Designed for in-vehicle infotainment and automotive applications.
- Features: Includes a locking mechanism, ruggedised housing, and shielding to resist vibration, dust, and interference.
HDMI Connector Types and HDMI Versions
| Connector Type | Pin Count | Typical Devices | Common HDMI Versions Used | Notes |
|---|---|---|---|---|

| Type B (Dual-Link HDMI) | 29 | Professional video gear (rarely used) | HDMI 1.0 (planned) | Intended for very high resolutions, but never widely adopted — superseded by HDMI 2.0/2.1 on Type A. |
| Type C (Mini HDMI) | 19 | Tablets, DSLR cameras, camcorders, portable devices | HDMI 1.3 → 2.0 | Smaller size, same functionality as Type A; commonly supports up to 4K @ 60Hz. |
| Type D (Micro HDMI) | 19 | Smartphones, ultrabooks, action cameras, compact devices | HDMI 1.4 → 2.0 | Ultra-compact connector; capable of 4K video but limited by device hardware. |
| Type E (Automotive HDMI) | 20 | In-vehicle infotainment, ruggedised systems | HDMI 1.4 → 2.0 (sometimes 2.1) | Ruggedised design with locking mechanism; extra pin for secure connection in harsh environments. |
