Comparison Between HDMI 1.4 Matrix and HDMI 2.0 Matrix

HDMI 1.4 and HDMI 2.0 are two different versions of the High-Definition Multimedia Interface, with significant differences in several aspects. Below is a detailed analysis of their key distinctions:

Bandwidth Support

HDMI 1.4: Supports a maximum bandwidth of 10.2 Gbps. While it can transmit 4K resolution (3840x2160) and 3D video, the refresh rate for 4K is limited, typically reaching only 24Hz or 30Hz.

HDMI 2.0: Supports a maximum bandwidth of 18 Gbps. This enhancement allows HDMI 2.0 to transmit higher-resolution video, including 4K at up to 60Hz, delivering smoother visuals.

Resolution & Refresh Rate

HDMI 1.4: Due to bandwidth limitations, it offers lower refresh rates for 4K video, which may result in less fluid motion.

HDMI 2.0: Supports higher resolutions and refresh rates, enabling 4K at 60Hz and even higher resolutions like 8K (though 8K is not yet widely adopted).

Color Depth

HDMI 1.4: Supports up to 8-bit color depth, providing relatively limited color representation.

HDMI 2.0: Supports higher color depth, up to 12-bit, offering a wider color gamut and more refined color performance for richer and more detailed images.

HDR Support

HDMI 1.4: Does not support HDR (High Dynamic Range), limiting its capability for high-quality video transmission.

HDMI 2.0: Supports HDR, providing a broader dynamic range and superior image quality with better detail in both bright and dark areas.

Audio Support

HDMI 1.4: Supports high-definition audio formats like DTS-HD Master Audio and Dolby TrueHD.

HDMI 2.0: Similar to HDMI 1.4 in audio but can support additional audio formats and channels for a more immersive audio experience.

Frame Rate & Sampling Rate Differences

HDMI 1.4: Despite supporting 4K resolution, its 10.2 Gbps bandwidth limits it to 3840×2160 at 30FPS.

HDMI 2.0: With 18 Gbps bandwidth, it supports 4K resolution at 50FPS or even 60FPS.

Other Features

HDMI 1.4: Supports Audio Return Channel (ARC) and Ethernet functionality, improving device interaction and data transfer efficiency.

HDMI 2.0: Retains HDMI 1.4 features while further enhancing performance and compatibility.
