HDMI 2.0 provides significant improvements and advantages over HDMI 1.4 in many aspects, including:
1. Higher bandwidth: The bandwidth of HDMI 2.0 is increased to 18Gbps, while HDMI 1.4 is 10.2Gbps. This allows HDMI 2.0 to transmit more data, support higher resolution and faster frame rate.
2. Higher resolution and frame rate: HDMI 2.0 supports 60Hz frame rate at 4K resolution (i.e. 3840x2160), while HDMI 1.4 only supports 24Hz or 30Hz at 4K. This means that HDMI 2.0 can provide a smoother and clearer ultra-high-definition video experience.
3. Enhanced color performance: HDMI 2.0 supports 10-bit color depth and can display about 1 billion colors. In contrast, HDMI 1.4 supports 8-bit color depth, which is about 16.7 million colors. This makes HDMI 2.0 richer and more delicate in color levels and transitions, especially when playing HDR (high dynamic range) content, it can show a wider color range and deeper black levels.
4. HDR support: HDMI 2.0 adds support for HDR (High Dynamic Range), which HDMI 1.4 does not support. HDR can provide greater contrast and richer colors, making the picture closer to the real world.
5. More powerful audio function: HDMI 2.0 supports more audio channels (up to 32 channels) and can handle higher resolution audio, such as audio with a sampling rate of up to 1536kHz, while HDMI 1.4's audio function is relatively weak.
6. Other advanced functions: including support for CEC extension (Consumer Electronics Control), dual-screen display, multi-audio stream transmission, 21:9 aspect ratio, and dynamic automatic sound and picture synchronization, which are not available in HDMI 1.4.
To sum up, HDMI 2.0 is an obvious upgrade choice for users who pursue high-quality audio-visual experience, especially for 4K high frame rate video, HDR content and more advanced audio requirements.
