Micro HDMI Connector: Just as mini-USB is employed with portable digital devices, a new "Micro HDMI" Connector is much smaller connector that can still supports up to 1080p resolutions for portable devices. This is very practical for video camcorders, digital still cameras, and portable digital video playback devices.

Automotive Connection System: With the increase of in-car digital audio/video devices, HDMI 1.4 can handle the more demanding vibration, heat, and noise that may affect the quality of audio and video reproduction.

HDMI 2.0

Expands the 4K (2160p) resolution compatibility of HDMI 1.4/1.4a to accept either 50Hz or 60Hz frame rates (maximum 18 Gbps transfer rate with 8 bit color).

Can accept up to 32 simultaneous channels of audio to accommodate future more-immersive surround sound format requirements.

Can accommodate up to a 1,536 kHz audio sampling rate to accommodate development of higher resolution audio formats.

Capability to send two independent video streams for viewing on the same screen.

Capability to send up to four separate audio streams to multiple listeners.

Support for the native 21:9 (2.35:1) aspect ratio.

Dynamic Synchronization of video and audio streams.

Expansion of HDMI-CEC capabilities.

For consumers that have components that only feature HDMI versions 1.0 through 1.3, you won't be able to access any added version 1.4, 1.4a, or 2.0 features, but you will still be able to use future 1.4/1.4a/2.0 enabled components with your current HDMI 1.0 to 1.3 components, you just wont have access to the newly added features.

In other words, don't raise your arms in the air in frustration, fall into the depths of despair, or start planning a garage sale in order to get rid of your old HDMI equipment - if your components continue to work the way you want them too (for instance, if you don't need 3D or 4K HDMI features), you are OK - the choice to upgrade is up to you.

HDMI 2.0a

Adds support for HDR (High Dynamic Range) technologies, such as HDR10 and Dolby Vision standards adopted by the CEA (Consumer Electronics Association).

What this means for consumers is that 4K Ultra HD TVs that incorporate HDR technology are capable of displaying a much wider range of brightness and contrast (which also makes colors look more realistic) than the average 4K Ultra HD TV that you see on store shelves.

However, in order to fully take advantage of this enhanced capability, the content being viewed has to be encoded with the necessary HDR metadata. This metadata, in turn, has to be transferred from a source to the TV via a connection, and since HDMI is the standard that is in place, it has stepped up to the plate. As of 2017, HDR encoded content is available via the Ultra HD Blu-ray Disc format and select streaming providers.

HDMI 2.0b

Extends HDR support to the Hybrid Log Gamma format, which is intended to be used in forthcoming 4K Ultra HD TV broadcasting platforms, such as ATSC 3.0.

HDMI 2.1

In January 2017, the HDMI consortium announced an additional upgrade to the HDMI platform, HDMI Version 2.1.

HDMI 2.1 specifications support the following features:

Video Resolution and Frame Rate Support: 4K 50/60, 4K 100/120, 5K 50/60, 5K 100/120, 8K 50/60, 8K 100/120, 10K 50/60, 10K 100/120.

Color Support: Wide Color Gamut (BT2020), at 10, 12, and 16 Bits.

HDR Support: Compatibility with Dynamic HDR formats - while Dolby Vision HDR, which is already compatible with HDMI 2.0a, contains dynamic HDR metadata that can change from frame-to-frame. - HDMI 2.1 will support any forthcoming similar HDR formats that may not be compatible HDMI ver 2.0a/b.

Audio Support: Just as HDMI 2.0 and 2.0a, all surround formats in use are compatible, including Dolby Atmos, DTS:X, and Audio 3D Audio.

Gaming Support: VRR (Variable Refresh Rate) is supported. This enables a 3D graphics processor to display the image at the moment it is rendered - allowing for more fluid and better detailed gameplay,including reduction or elimination of lag, stutter, and frame tearing.

Cable Support: 48Gps - if order to access the full capabilities of HDMI ver 2.1 enabled devices, an HDMI cable that supports a 48Gps transfer rate is required).

HDMI ver 2.1 enabled devices and cables forthcoming - Stay Tuned.

The Future of HDMI

As you upgrade and purchase audio and video components, you will notice HDMI becoming more of a standard connection option with increasing capabilities. Eventually, the cable jungle behind your home theater system will disappear, as all the audio and video cables are reduced to one HDMI cable between each component for both audio and video. This is great news for consumers.
