It also features a shell to protect against environmental hazards like moisture and dirt. Type E: Used in automotive applications, Type E has locking tabs to keep the cable inserted during vibration in its environment. Type D: Known as “micro HDMI” and roughly the same size as a micro-USB connector (5.83 x 2.20mm), Type D also has 19 pins, but a configuration different from either Types A or C.Ĥ. Type C: Often referred to as “mini HDMI,” this connector is considerably smaller (10.42 x 2.42mm) and retains the 19-pin configuration, though it swaps the position of the positive signals with their corresponding shields.Ĥ. Single-link HDMI speed eventually outstripped the speeds possible in the dual-link concept.ģ. Type B: This type was designed as a dual-link version to increase data speeds but was never implemented.
These connectors are compatible with the older DVI-D connector.Ģ. There is enough bandwidth to carry all modes of video up to 4K. The remaining pins carry information like the CEC signal. It has 19 pins, the bulk of which carry video, audio, and timing data and are assigned in groups of three: a positive/negative pair with a pin that acts as an interference shield between them. Type A: This is the standard HDMI connector (13.90 x 4.45mm), available on virtually all HD TVs. The HDMI standard includes five types of connectors, referred to as types A-E:ġ. Some HDMI cables are available with an Ethernet channel as well, which allows high-speed bidirectional data transfer. The CEC signal enables the use of a single remote control to operate all the connected devices. HDMI cables also carry a Consumer Electronics Control (CEC) signal that allows HDMI-connected devices to control each other. This versatility allows the user to simplify their setup by using only one cable for both audio and video without sacrificing signal quality. Unlike the DVI interface that came before it, HDMI can send uncompressed video signals along with either compressed or uncompressed audio signals using a single cable (DVI could only send video). HDMI stands for “High Definition Multimedia Interface.” Just as the name suggests, HDMI functions by passing high-quality audio and video signals. HDMI is the gold standard today, but not all HDMI cables are created equal. Fortunately, as we move into an increasingly digital world, options are getting simpler and more straightforward, so a little information can go a long way towards clarifying your best choice.
