They are currently among the industry’s top connectors. There are, nevertheless, some significant points of distinction between them.

HDMI 1.3 vs HDMI 1.4

The difference between HDMI 1.3 and HDMI 1.4 is that in comparison to HDMI 1.3, HDMI 1.4 has a significantly greater resolution. The first HDMI cable discussed is version 1.3, which is quicker than prior versions and provides more bandwidth for connecting to HD sources like a Blu-ray player, high-definition cable box, or satellite network.

HDMI 1.3 vs HDMI 1.4

Automatic audio synchronization features are built into HDMI 1.3, allowing devices to conduct this synchronization automatically and with extreme precision. It supports a high resolution of 4K, which is a plus point.

The new HDMI protocol lets gadgets enable exceptionally high HD images, up to four times that of 1080p equipment.

HDMI 1.3 provides a new, lower form factor attachment option for small mobile devices such as HD camcorders and still cameras that require smooth access to HDTVs.

HDMI 1.4 adds a transmission medium to the HDMI connection, allowing for high-speed bi-directional transmission.

This functionality lets connected devices transmit information over a 100 Mb/sec Ethernet connection, making them instantaneously ready for any IP-based application.

The HDMI 1. 4 protocol establishes the general 3D formats and resolutions for HDMI-enabled devices, allowing 3D gaming and other 3D video apps.

Comparison Table

Parameters of ComparisonHDMI 1.3HDMI 1.4
ResolutionThis cable does not have as good a resolution as HDM1 1.4, which is one of its disadvantages.This version has a more improved resolution. This quality is one of the advantages of using this.
3D SupportThis cable only supports 3D in 1080i.This cable supports 3D completely. This quality is another of its plus points.
Ethernet ChannelThis cable does not have an Ethernet channel.This cable has an Ethernet channel.
Cable StandardsThis cable has older cable standards than version 1.4.This cable has newer cable standards than version 1.3.
Audio return channelThis cable does not have an audio return channel which is another of its cons. This cable has an audio return channel, unlike version 1.3.

What is HDMI 1.3?

To handle the requirements of the future HD display technologies, such as better resolution, Rich Color, and high frame rates, HDMI 1.3 raises its single-link bandwidth to 340 MHz (10.2 Gbps).

Furthermore, the HDMI 1.3 standard includes the technical fundamentals which will allow future HDMI versions to attain substantially faster speeds.

HDMI 1.3 enables color levels of 10-bit, 12-bit, and 16-bit (RGB or YCbCr), up from 8-bit depths in prior HDMI versions, allowing for a breathtaking depiction of over one billion colors in extraordinary detail.

HDMI 1.3 includes support for “x.v. ColorTM” (the consumer term for the IEC 61966-2-4 xvYCC color standard), which eliminates present color space constraints and allows for the display of any color visible to the naked eye.

HDMI 1.3 provides a new, lower form factor attachment choice for compact portable devices such as HD camcorders and still cameras that require smooth access to HDTVs.

As consumer technology devices are dependent on extensive digital signal processing to improve content clarity and detail, synchronizing sound and video in connected systems has become a more difficult task that may necessitate complex end-user changes.

Automatic audio synchronization features are built into HDMI 1.3, allowing devices to conduct this synchronization instantly and with pinpoint accuracy.

What is HDMI 1.4?

HDMI 1.4 offers a transmission medium to the HDMI connection, allowing for high-speed bi-directional transmission.

The HDMI Ethernet Channel enables internet-enabled HDMI devices to share a connection to the internet without the use of a separate Ethernet cable across the HDMI link.

It also acts as a connecting platform, allowing HDMI-enabled equipment to share content.

The new standard adds an audio line, reducing the number of connections needed to send audio “upstream” from a TV to an A/V receiver for processing and playback.

The Audio Return Channel allows a TV with an inner content source, such as an installed tuner or DVD player, to transfer audio data upstream to the A/V recipient via the HDMI cable, removing the need for an additional cable.   

The new HDMI protocol allows devices to enable exceptionally high HD images, up to four times that of a 1080p device.

With 4K support, the HDMI interface can transport digital video at the same resolution as many movie theatres’ state-of-the-art Digital Cinema systems.

The HDMI 1.4 protocol establishes common 3D formats and resolutions for HDMI-enabled devices, allowing for 3D gaming and other 3D video apps.

The protocol standardizes the input/output element of a home 3D system, allowing for dual-stream 1080p 3D qualities.

Main Differences Between HDMI 1.3 and HDMI 1.4

  1. HDMI 1.4 does not have as good a resolution as HDM1 1.4. This quality is one of its disadvantages. 
  2. The HDMI 1.3 only supports 3D in 1080i, while HDMI 1.4 fully supports 3D. This quality is again a very strong plus-point of using HDMI 1.4.
  3. HDMI 1.3 does not have an Ethernet channel whereas, HDMI 1.4 has an Ethernet channel. Therefore, no doubt HDMI 1.4 is better than HDMI 1.3 based on this aspect.
  4. HDMI 1.3 has older cable standards than HDMI 1.4.
  5. HDMI 1.3 is not equipped with an audio return channel which is another of its cons. On the other hand, HDMI 1.4 is a more improved version of HDMI, has an audio return channel.
