Type D
A Micro connector defined in the HDMI 1.4 specification[52][55] keeps the standard 19 pins of types A and C but shrinks the connector size to something resembling a micro-USB connector.[56] The type D connector is 2.8 mm × 6.4 mm, whereas the type C connector is 2.42 mm × 10.42 mm;[57] for comparison, a micro-USB connector is 2.94 mm × 7.8 mm and USB Type A is 11.5 mm × 4.5 mm.
