What is an HDMI connector?
An HDMI connection is a vital I/O ( input-output ) hardware component in many modern pieces of entertainment or communications equipment. They enable HDMI cables to transfer decompress digital signals from any suitable audio-video ( A/V ) reservoir to the receiver or display device it ’ mho plugged in to .
In a huge number of advanced homes and workplaces, HDMI connectors are very likely to be found linking desktop computers to monitors, TVs to set-top boxes, games consoles to projectors, and much more besides. In fact, across all fields of home entertainment and workplace communications technologies, HDMI is nowadays one of the most democratic and widespread formats for carrying high-quality A/V signals between source and display.
HDMI stands for High Definition Multimedia Interface. This high-end modern format was initially developed in the very early 2000s, with the original drive of improving on the overall convenience and functionality of existing standards for carrying HDTV signals .
anterior to HDMI, these were basically limited to either DVI or component video. The former, a video-only connection, was better suited to its original use in calculator monitors, The latter, although effective at transferring HD signals once hooked up, required users to route up to five separate cables if they wanted both video recording and audio to transfer simultaneously.
HDMI was basically developed as a think of of gathering these five classify cables into one. And, after a period of acute inquiry and testing worldwide, HDMI first launched as a range of commercially available cable and connectors in 2002 .
Sales of HDMI components began to increase exponentially over the following 3-5 years, and today it has become more or less the default option for home and workplace A/V signal transfer alike. True to the developers ’ original vision, HDMI now allows highly high-quality audio-visual signals to be carried faithfully and neatly between adequate to electrify devices via a single uncompromising cable .
HDMI connectors themselves function much like any other familiar cable-based plug and socket system. indeed, there ’ s a noteworthy similarity in appearance between USB and HDMI, although HDMI is typically larger ( we ’ ll look more closely at shapes and sizes in the pursuit sections ) .
As with most early audio-video cable components, HDMI connectors are gendered and can be either male or female depend on which side of the interface they ’ rhenium required to support in order to complete the connection. And, as is the norm with cable plugs and sockets, a male HDMI connection will by and large be slenderly smaller and feature a bulge peg area, while the female connection will be recessed and slenderly larger .
In summation to these basic male/female characteristics, there are besides a number of unlike HDMI connection types, sizes and layouts available to buy in the UK and cosmopolitan .
In this lead, we ’ ll explore some of the more common sorts of HDMI connectors on sale in the current market, and look at which types tend to be good suited to what sorts of applications
HDMI connector specifications
broadly speaking, HDMI connectors are noteworthy among other types of electrify connectors and terminals for the quality, bandwidth and speed of the A/V signals they ’ re able to carry. Since the first HDMI products were launched in 2002, there have been a number of revisions and official iterations of the HDMI standard, each of which delivered its own update set of HDMI connection specifications .
To date, the key HDMI revisions have been :
HDMI Version ( Year released )
- HDMI 1.0 (2002)
- HDMI 1.1 (2004)
- HDMI 1.2 and 1.2a (2005)
- HDMI 1.3 (2006)
- HDMI 1.4, 1.4a and 1.4b (2009, 2010, 2011)
- HDMI 2.0, 2.0a and 2.0b (also known as HDMI UHD) (2013, 2015, 2016)
- HDMI 2.1 (2017)
broadly speaking, each of these revisions delivered consecutive expansions in overall functionality and performance, and then the universal HDMI connection spectacles have constantly been evolving over the life of the format to date .
version 1.2 ( 2005 ), for exercise, broadened the scope of resolutions and refresh rates supported by HDMI, in a successful undertake to popularise the format among calculator owners. version 1.4 ( 2009-2011 ) added defend for 4k signals and shared Ethernet connectivity between devices, while version 2.0 ( 2013-2016 ) dramatically improved both video bandwidth and sound recording sample frequency, allowing for coincident stream of HDR visuals and moral force audio-video synchronization .
What does an HDMI connector look like?
As mentioned in the opening section, an HDMI connection looks not wholly unlike to a USB connection. In each case, the male sides of the connection normally protrude from the cable ends and are typically intended for insertion into female connectors, sockets or hubs that are recessed into the devices being linked .
There are, however, a couple of noteworthy physical differences between USB and HDMI. Full-size HDMI connectors are slenderly larger than standard USB, and they ’ re besides characteristically trapezium-shaped, with opposing faces/slot sides of inadequate duration .
The HDMI connection diagram below shows the authoritative delineate that many people will recognise immediately from I/O panels of their own TVs, games consoles and calculator monitors :
While there are diverse sizes and configurations of HDMI cables and connectors available, the ones in a widespread daily home or position use all tend to share this like basic shape and layout.
HDMI connector types
There are multiple different types of HDMI cable connectors sold on today ’ second marketplace. Although they all basically do the same matter, they ’ re not normally exchangeable in any specific application or device. In other words, you ’ ll need to know which connection type you ’ re going to be using before making a buy.
There are presently five standard connection types available for HDMI cables, namely :
- Type A (standard)
- Type B (dual link – not currently used in any mainstream consumer products)
- Type C (mini)
- Type D (micro)
- Type E (the Automotive Connection System, chiefly developed for in-vehicle use)
These assorted HDMI cable connection types are easy enough to identify physically, due to their perceptibly different sizes. however, if you ’ re not companion with the appoint schemes for HDMI subtypes, then the crop of available options can look a little jumble at first glance. Rest assured that, for the huge majority of home and workplace applications, HDMI connection types A, C and D ( standard, mini and micro ) will be the only versions you ’ ll generally need.
HDMI type A connector
The type A HDMI connection is the archetypal ‘ standard ’ translation of HDMI that most users would immediately recognise, and silent the most widely used and readily available of the five current connection sizes. They ’ re by far the most familiar of HDMI connection types to most people and are found on about every brand of mod television, admonisher, games console and desktop calculator

HDMI type C mini connector
Type C mini HDMI connectors are a smaller, slimmed-down version of type A, and are very normally found on diverse sorts of portable equipment – distinctive examples might include DSLR cameras, camcorders, larger tablets and sit nav systems. Type C mini HDMI plugs bill 10.42mm × 2.42mm .
HDMI type D micro connector
Type D HDMI connectors are the micro versions. These are smaller than both standard and mini HDMI connectors, but again retain the same 19-pin configuration ( albeit in a slenderly different layout due to the size constraints of the microformat ) .
Female and male HDMI connectors
HDMI female connectors are normally found built into both the signal beginning device and the experience device, as sockets intended for a male-end cable to connect to. In the most common arrangement, a cable with two male ends is plugged into two female sockets simultaneously, providing direct wired connectivity between the source and display devices .
Because female HDMI connectors are normally recessed into the body of TVs, games consoles, projectors, computers and monitors – and because they tend to be more susceptible to deforming under excessive try than male connectors – they ’ re more widely sold as standalone refilling parts .
male HDMI connectors, on the early hand, are broadly supplied as fasten components at either end of about every commercially available HDMI cable, and so in many situations, it ’ second easier and cheaper to replace a damaged male connection by simply swapping in a new cable. however, this international relations and security network ’ thymine constantly hardheaded : some high-end HDMI cables can be relatively expensive ( specially the longer and sturdier types ), and so in many cases, it can be well cheaper to wire on a new male connection than to replace an entire cable operate .
In addition, many people choose to route HDMI cables behind walls or between floors of a construct, and it can be a complicate summons to remove and re-lay these if person happens to step on one of the male connectors and damage it. For this reason, most authentic suppliers that stock female HDMI sockets will besides offer a range of equivalent male components excessively.
Straight and right-angle HDMI connectors
When plugged in, a standard directly connection for HDMI extends horizontally out of the female socket, much like a standard USB cable or 3.5mm jacklight ballyhoo does. This is the most common type of HDMI connection, and will by and large be suitable for the majority of family and workplace setups .
however, in scenarios where the sum of outer space immediately in front of an HDMI socket is limited, it ’ randomness besides potential to purchase justly angled HDMI connectors. These are designed to point immediately down on exiting the socket, which helps the connection and the cable model flush against the device it ’ mho plugged into .
HDMI right-angle connectors can be particularly utilitarian if a television receiver or computer is placed with its I/O ports very close to a wall, for exercise, or if the relative positions of reservoir and recipient devices would put excessive strain on a straight HDMI connection. It can besides be handy for improving general cable management around the back of many device types, helping to keep things neat and easy to access .
What is an HDMI connector used for?
In about all standard use scenarios, HDMI cables and connectors of all types will be used to transfer coincident audio and video recording signals from a source to a liquidator or display. After all, that ’ s what they were originally developed to do, without users having to link up multiple different sets of cables ( or the much more gawky DVI connectors ) to get both types of signal carried at once .
however, in some cases, HDMI can besides be used strictly for either audio or television signals due to its wide backwards compatibility with older connection standards. This is particularly useful because, with the addition of the right adapter, it allows HDMI cables and connectors to link hardware devices with a number of different port types .
Audio and video use
As covered earlier in this guide, HDMI was primitively developed to update and replace the existing DVI connection standard still found on many calculator monitors and other items of video display hardware. DVI is a video-only output, and although HDMI can carry both audio and video recording signals at the like clock time, it ’ sulfur besides electrically compatible with the DVI interface .
By purchasing an HDMI-DVI connection, users can run HDMI cables out from DVI sockets on older hardware and display the result image absolutely on more modern screens or receivers that lack their own DVI port. similarly, HDMI audio connectors can besides be used to convey barely the sound signals from devices with older-style part audio ports if the correct adapter is used.
nowadays ’ south HDMI connectors provide a wealth of options for transferring very high quality, high bandwidth audio-video signals between a wide-eyed range of modern entertainment and communications equipment. And, thanks to their engineered backwards compatibility with earlier audio-video transmit formats, they can besides provide a utilitarian link-up between devices that lack identical HDMI ports if the correct adapter is chosen.
