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.
