There are currently five main types of HDMI (High-Definition Multimedia Interface) connectors. However, only four are commonly found in consumer electronics.
HDMI Connector Types
Here's a breakdown of the different HDMI port types:
-
Type A (Standard): This is the most common HDMI connector. It's found on most TVs, monitors, gaming consoles, and other devices. It has 19 pins.
-
Type B (Dual-Link): Type B has 29 pins and was designed for very high-resolution displays, exceeding what Type A could handle at the time of its development. However, it hasn't seen widespread adoption and is rarely used in consumer products. The newer versions of HDMI Type A have surpassed the capabilities of the Type B, making it obsolete.
-
Type C (Mini): The Mini HDMI connector is smaller than the standard Type A, making it suitable for devices like camcorders and some tablets. It also has 19 pins but in a smaller form factor.
-
Type D (Micro): The Micro HDMI connector is even smaller than the Mini HDMI connector. It's commonly found on smartphones, smaller tablets, and digital cameras. Like the others (except Type B), it has 19 pins.
-
Type E (Automotive): This connector is designed for use in vehicles. It features a locking mechanism to prevent accidental disconnections, and it's built to withstand the vibrations and temperature extremes found in automotive environments.
Summary Table
| Connector Type | Size | Common Use Cases | Pins | Notes |
|---|---|---|---|---|
| Type A | Standard | TVs, monitors, gaming consoles, DVD players, Blu-ray players, streaming devices | 19 | Most common type |
| Type B | Dual-Link | (Rarely Used) - High-resolution displays (historical) | 29 | Largely obsolete |
| Type C | Mini | Camcorders, some tablets | 19 | Smaller form factor than Type A |
| Type D | Micro | Smartphones, small tablets, digital cameras | 19 | Smallest form factor for consumer electronics |
| Type E | Automotive | In-vehicle entertainment systems | 19 | Designed for automotive environments |
In conclusion, while five types of HDMI connectors exist, the Standard (Type A), Mini (Type C), Micro (Type D), and Automotive (Type E) are the most relevant in today's market. The Dual-Link (Type B) is largely obsolete.
