The High-Definition Multimedia Interface (HDMI) has revolutionized the way we enjoy multimedia content. As technology advances, HDMI has also evolved to meet the growing demands of high-definition audio and video. One such milestone is HDMI 1.4b, which was introduced in 2009. In this article, we will delve into what HDMI 1.4b can support, its key features, and the benefits it offers.
A Brief Overview of HDMI 1.4b
HDMI 1.4b is a minor update to the HDMI 1.4 standard, which was released in 2009. This version offered several improvements over its predecessors, including increased bandwidth, new audio formats, and networking capabilities. HDMI 1.4b was a necessary update to clarify some of the ambiguities in the original 1.4 standard, particularly regarding the support for 3D video and the Audio Return Channel (ARC).
Key Features of HDMI 1.4b
HDMI 1.4b supports several key features that make it an attractive choice for consumers and manufacturers alike. Some of these features include:
- Increased bandwidth: HDMI 1.4b supports bandwidth speeds of up to 10.2 Gbps (gigabits per second), which is a significant increase over the 4.95 Gbps bandwidth of HDMI 1.3.
- 3D video support: HDMI 1.4b supports the transmission of 3D video content at resolutions up to 1080p (1920×1080) and 60Hz.
- Audio Return Channel (ARC): HDMI 1.4b supports the Audio Return Channel, which allows the television to send audio signals back to the soundbar or home theater system without the need for a separate audio cable.
- Ethernet connectivity: HDMI 1.4b supports Ethernet connectivity over a single HDMI cable, making it possible to connect devices to the internet without the need for a separate Ethernet cable.

What is HDMI 1.4b and what are its key features?
HDMI 1.4b is an updated version of the HDMI 1.4 standard, which was released in 2010. This version supports some additional features such as 3D video and Ethernet connectivity. HDMI 1.4b also supports ARC (Audio Return Channel) and it can transmit both video and audio signals over a single cable.
The key features of HDMI 1.4b include support for 4K resolution at 30 Hz, 3D video, and ARC. It also supports up to 120 Hz refresh rate and a maximum bandwidth of 21 Gbps. Additionally, HDMI 1.4b can support up to 8 channels of 192 kHz audio and Dolby TrueHD, and DTS-HD Master Audio.
What is the difference between HDMI 1.4 and HDMI 1.4b?
The main difference between HDMI 1.4 and HDMI 1.4b is the addition of new features such as 3D video and Ethernet connectivity in the later version. HDMI 1.4 was released in 2009 and it supported resolutions up to 4K at 30 Hz, but it did not support 3D video. HDMI 1.4b was released in 2010 and it added support for 3D video, ARC, and Ethernet connectivity.
HDMI 1.4b also has some minor improvements over HDMI 1.4 in terms of audio and video transmission. It can support more audio channels and has a higher maximum bandwidth. However, both versions of the standard have the same maximum resolution and refresh rate.
What are the benefits of using HDMI 1.4b?
The main benefits of using HDMI 1.4b are its support for 3D video, ARC, and Ethernet connectivity. These features make it a more versatile and convenient option for consumers who want to connect multiple devices to their TV or monitor. HDMI 1.4b also supports higher refresh rates and resolutions, which can improve the overall viewing experience.
Another benefit of using HDMI 1.4b is that it can simplify the setup process for home theaters and other audio-visual systems. With ARC, users can transmit audio signals from their TV to their soundbar or receiver, eliminating the need for a separate audio cable. HDMI 1.4b can also support more audio channels, which can improve the overall sound quality.
What devices support HDMI 1.4b?
HDMI 1.4b is supported by a wide range of devices, including TVs, monitors, soundbars, and receivers. Many modern TVs and monitors are equipped with HDMI 1.4b ports, which can support 3D video, ARC, and Ethernet connectivity. Soundbars and receivers also often have HDMI 1.4b ports, which can receive audio signals from TVs or send them to other devices.
Other devices that may support HDMI 1.4b include Blu-ray players, game consoles, and computers. These devices often have HDMI ports that can support resolutions up to 4K and refresh rates up to 120 Hz. However, not all devices support HDMI 1.4b, so users should check the specifications of their devices before purchasing new equipment.
How do I know if my device supports HDMI 1.4b?
To determine if your device supports HDMI 1.4b, you should check the device’s specifications. Most devices will have a label or documentation that indicates the version of HDMI they support. If your device supports HDMI 1.4b, it will be able to transmit 3D video, ARC, and Ethernet signals over a single cable.
You can also check the device’s HDMI ports to see if they are labeled as “HDMI 1.4b” or “HDMI 1.4”. If the ports are labeled as “HDMI” without a version number, it may still support HDMI 1.4b, but it may not be guaranteed. In this case, you may need to consult the device’s manual or manufacturer’s website to determine if it supports HDMI 1.4b.
Can I use HDMI 1.4b with my existing cables?
In most cases, HDMI 1.4b devices can be used with existing HDMI cables. However, the cable must also support the bandwidth and features of HDMI 1.4b. If you have an older HDMI cable that only supports HDMI 1.3 or earlier, it may not be able to transmit 3D video or ARC signals.
To ensure that you can take full advantage of HDMI 1.4b’s features, you may need to upgrade to a newer HDMI cable that supports higher bandwidths and features. These cables are often labeled as “HDMI 1.4b” or “HDMI High-Speed”. If you are unsure whether your existing cable supports HDMI 1.4b, you can consult the manufacturer’s website or documentation.
What is the future of HDMI 1.4b?
HDMI 1.4b is still a widely supported standard, but it has been largely replaced by newer versions of HDMI such as HDMI 2.0 and HDMI 2.1. These newer versions support higher resolutions, refresh rates, and bandwidths, and they offer additional features such as variable refresh rate (VRR) and auto-low-latency mode (ALLM).
However, HDMI 1.4b is still widely used in many devices, and it will likely continue to be supported for the foreseeable future. As devices and standards continue to evolve, it’s possible that HDMI 1.4b may eventually be phased out in favor of newer versions, but for now, it remains a widely supported and versatile standard.
