HDMI Mini vs HDMI Micro

HDMI Mini vs HDMI Micro

So what's the difference between the HDMI mini connector and HDMI micro connector? Let's look at some of the specs.

HDMI Mini Connector:

- Type C HDMI
- 10.42 mm × 2.42 mm
- Defined in the HDMI 1.3 specification
- 19-pin configuration

HDMI Micro Connector:

- Type D HDMI
- 6.4mm x 2.8 mm
- Defined in the HDMI 1.4 specification
- 19-pin configuration

As you can see, they both employ the 19-pin configuration, but the Mini HDMI (Type C) is different because all positive signals of the differential pairs are swapped with their corresponding shield, the DDC/CEC Ground is assigned to pin 13 instead of pin 17, the CEC is assigned to pin 14 instead of pin 13, and the reserved pin is 17 instead of pin 14. The Micro (Type D) uses the same pin configuration as the standard HDMI (Type A).

Mini HDMI (Type C) to Standard HDMI (Type A) cables are generally used for connecting your HD camcorder to your HDTV.

Micro HDMI (Type D) to Standard HDMI (Type A) cables are used for connecting smart phones like the Motorola Droid X and Sprint HTC Evo to HDTVs.

Video shows the Motorola Droid X getting hooked up to an HDTV via the HDMI Micro cable:


  1. The HDMI type B connectors are not used yet. They are larger (21.2 mm × 4.45 mm) and have 29 pins, vs the regular 19 pin HDMI. The additional 10 pins allow it to carry double the video bandwidth for very high-resolution future displays such as WQUXGA (3840 x 2400)

  2. The picture was everything I needed.

    I love you interwebs.

  3. Why are they making things so complicated :)

  4. Different sizes for different applications. But I agree, just get rid of the Mini and have HDMI and HDMI Micro.

  5. Perfect picture of the difference between each HDMI connector. Thanks!

    1. I'm in the same boat as everybody, just make one connector for the same thing!!!
