What is HDR?
Before we dive into the specifics of HDMI 1.4b and HDR, it’s essential to understand what HDR is and how it works. HDR is a display technology that offers a more immersive viewing experience by providing a wider range of colors, contrast levels, and brightness. HDR content is mastered to take advantage of the increased color gamut and contrast ratio, resulting in a more lifelike and engaging visual experience.
There are several types of HDR, including:
- HDR10: An open standard for HDR that offers a peak brightness of up to 1,000 nits
- HDR10+: An enhanced version of HDR10 that offers dynamic metadata and a peak brightness of up to 4,000 nits
- Dolby Vision: A proprietary HDR format that offers dynamic metadata and a peak brightness of up to 10,000 nits
HDMI 1.4b and HDR: What’s the Verdict?
Now that we have a better understanding of HDR, let’s explore whether HDMI 1.4b supports it. The answer is a bit complicated. While HDMI 1.4b does offer some features that are similar to HDR, such as increased bandwidth and improved color accuracy, it does not officially support HDR.
The main reason for this is that HDMI 1.4b does not have the necessary bandwidth to support the increased color gamut and contrast ratio required for HDR. Additionally, HDMI 1.4b does not support the necessary metadata required for HDR, such as dynamic metadata.
However, some devices that use HDMI 1.4b may still be able to display HDR content, albeit with some limitations. For example, some TVs may be able to display HDR content using HDMI 1.4b, but the quality may not be as good as it would be with a newer version of HDMI, such as HDMI 2.0 or later.
Why is HDMI 2.0 or Later Required for HDR?
So, why is HDMI 2.0 or later required for HDR? The main reason is that HDMI 2.0 and later versions offer several features that are necessary for HDR, including:
- Increased bandwidth: HDMI 2.0 and later versions offer a much higher bandwidth than HDMI 1.4b, which is necessary for the increased color gamut and contrast ratio required for HDR.
- Support for HDR metadata: HDMI 2.0 and later versions support the necessary metadata required for HDR, such as dynamic metadata.
- Improved color accuracy: HDMI 2.0 and later versions offer improved color accuracy, which is necessary for the increased color gamut required for HDR.
In summary, while HDMI 1.4b does offer some features that are similar to HDR, it does not officially support HDR due to its limited bandwidth and lack of support for HDR metadata.

What is HDMI 1.4b and how does it differ from other HDMI versions?
HDMI 1.4b is a version of the High-Definition Multimedia Interface (HDMI) standard that was released in 2011. It is an update to the HDMI 1.4 standard and offers several improvements, including support for 3D video and higher resolutions. HDMI 1.4b is capable of transmitting video signals at resolutions up to 4K (3840 x 2160 pixels) at 30 Hz, as well as audio signals with up to 8 channels.
One of the key differences between HDMI 1.4b and other HDMI versions is its support for 3D video. HDMI 1.4b is capable of transmitting 3D video signals using a variety of formats, including frame packing, side-by-side, and top-and-bottom. This allows for a more immersive viewing experience, with a wider range of 3D content available. Additionally, HDMI 1.4b supports higher resolutions than earlier HDMI versions, making it a popular choice for applications where high-quality video is required.
Does HDMI 1.4b support HDR (High Dynamic Range) content?
HDMI 1.4b does not officially support HDR (High Dynamic Range) content. While it is capable of transmitting video signals with a wide color gamut, which is a key component of HDR, it does not have the necessary bandwidth to support the full range of HDR formats. In particular, HDMI 1.4b lacks support for HDR10, which is a widely-used HDR format that requires a higher bandwidth than HDMI 1.4b can provide.
However, some devices that use HDMI 1.4b may be able to transmit HDR content using a technique called “tone mapping.” This involves reducing the dynamic range of the HDR content to make it compatible with the lower bandwidth of HDMI 1.4b. While this can provide some of the benefits of HDR, it is not a true HDR experience and may not offer the same level of picture quality as a device that supports HDR natively.
What are the limitations of HDMI 1.4b when it comes to HDR support?
One of the main limitations of HDMI 1.4b when it comes to HDR support is its bandwidth. HDMI 1.4b has a maximum bandwidth of 10.2 Gbps, which is not enough to support the full range of HDR formats.
