HDMI Full Form

We must have utilized a variety of cords to connect different computer peripherals or our digital devices. One of the most often utilized cables is HDMI. It's an all-digital audio-video interface that sends uncompressed video data and compressed or uncompressed digital data from an HDMI-compliant source device to a computer monitor, video projector, digital television, and so on. It is a digital replacement for analog video and audio standards that have been widely used for decades. Consumer HDMI was first produced in late 2003. Since then, several versions of HDMI have been developed and released; all come with a cable and connector.

Here, we will learn HDMI full form in computer, full form of HDMI port, different types of HDMI cable and their advantages as well as disadvantages.

HDMI Cable Full Form

HDMI cable full form is High Definition Multimedia Interface. HDMI serves as a connection point for audio and video signals between various multimedia devices.

Types of HDMI Cable

There are two types of HDMI cables that are widely used worldwide.

• Standard Cable

• High-Speed Cable

Standard Cable: It's also known as a Category 1 HDMI cable. It operates at 75 Mhz pixel speeds and has a bandwidth of roughly 2.23 Gbps. It is capable of broadcasting a 1080i signal without compression.

High-Speed Cable: High-Speed​​Cable is also known as Category 2 HDMI cable. It has a pixel speed of 10.2 Gbps and operates at bandwidth support of 340 MHz. It works well with the new 1440p and WQXGA resolutions. Despite the fact that HDMI cables do not support 4K resolution, the picture quality is still superior to that of other cables.

Advantages

Following are the advantages of HDMI cable:

• We don't need separate audio cords because it carries both visual and audio signals.

• It allows you to establish many connections using a few cables that simplify the connection process and eliminate the clutter of multiple cables.

• It allows you to turn your TV into a computer monitor as the latest computers and laptops come with an HDMI connection.

• A specific adapter that gives more connection choices can be used to convert it to DVI.

• It can play a variety of audio formats, including normal stereo, multi-channel surround sound, and so on.

• It is capable of playing high-definition video formats (720p, 1080i, etc). It can support both high-definition formats like 480p and standard-definition formats like PAL and NTSC.

HDMI Full Form in Computer

HDMI ports present on the back of the computer is shown below:

The HDMI ports are located on the back of the computer, either on the video card or on the motherboard. It's important to note that HDMI ports aren't available on all PCs and video cards.Our computer may use a display port, DVI, or VGA technology. These are the HDMI in computer full form.

How HDMI Cable Works?

The HDMI cable transmits all signals in digital format from one device to another. The benefit is that it does not require the employment of a converter to convert the format at any point in time, and the media's clarity is preserved. Both the TV and the player's circuits become small and intensive. Audio and video signals are delivered in digital form to a TV or monitor via this sort of connection. An HDMI cable has 19 wires, each of which is attached to a connector that transmits a digital signal in audio-video format from one device to another at high speed and with excellent quality.

HDMI Ports and Connectors

Type A (Standard), Type C (Mini), and Type D (Micro) HDMI connectors are the most common in use today. Type B (Dual-Link) HDMI was created for extremely high-resolution monitors but was never deployed. Also available is the HDMI Type E connector, which is designed for automotive and industrial use.

Of the five HDMI connector types, the Standard HDMI connector (Type A) is the most extensively used. Almost every brand of TV, computer monitor, game console, streaming device, and the desktop computer has a 19-pin connector.

Type A is shown in the diagram below.

Mini HDMI connectors (Type C) include 19 pins and provide the same functionality as full-sized Type-A connectors in a smaller, more compact package. It is commonly utilized on portable devices such as DSLR cameras and tablets due to its lower size.

Type C Mini HDMI plugs measure 10.42mm × 2.42mm. Type C Mini HDMI connectors are a smaller, slimmed-down version of type A.

Type C is shown in the diagram below.

Micro HDMI (Type D), the smallest HDMI connector, is about half the width of the Mini HDMI connector but retains all of the functions of its larger brothers. Micro HDMI connectors are commonly seen on small, portable devices like phones.

Type D micro HDMI connectors measure just 5.83mm × 2.20mm, which makes them similar in overall size to a micro-USB connector, and less than half the size of a standard HDMI type A plug or socket. Type D was designed primarily for audio-video communication in a compact, portable devices like cell phones.

Type D is shown in the diagram below.

Type E shown in the above diagram (the Automotive Connection System, chiefly developed for in-vehicle use))

As we know HDMI cable is low voltage, it can be installed inside a wall. HDMI faceplates contain a female connector on the interior side for quick termination and a clean, finished appearance. HDMI keystones are also available for digital signs and big meeting facilities with many displays fed from a single source.

Limitations of HDMI cable

Limitations of HDMI cable is given below:

• While using HDMI sometimes authentication delay can happen which causes a blank screen, which is an irritating thing.

• HDMI cables as well as HDMI-supported devices are costlier than others.

• Field terminations of HDMI cables have limits.

• When devices change their setup, CEC (Consumer Electronics Control) produces confusion since the control systems may not detect it.

• HDMI uses DVI interfacing so it needs an HDMI-DVI adapter to connect the audio, otherwise, the audio cannot be connected.

• Using HDMI to run many applications at the same time is tough.

Conclusion

HDMI full form is similar to  Long form of HDMI, i.e, High Definition Multimedia Interface. Today’s HDMI connectors provide a variety of options for transferring very high quality, high bandwidth audio-video signals between a wide range of modern entertainment and communications equipment.

HDMI cables and connectors of all types will be utilized to transfer simultaneous audio and video signals from a source to a receiver or display in practically all conventional application situations. We have discussed HDMI long form, HDMI port full form, and types of HDMI cables.
