One of the main limitations is the restricted bandwidth of HDMI 1.4, which falls short in delivering the necessary data transfer rates for a seamless 4K 60Hz display.
To overcome this, HDMI 1.4 utilizes a process called chroma subsampling, which reduces the amount of color information transmitted from the source to the display. This compromise results in a noticeable loss of image quality, particularly in terms of color accuracy and sharpness.
Another limitation lies in the maximum resolution and frame rate combination that HDMI 1.4 can handle. While it can support 4K resolution at 30Hz, attempting to push the frame rate to 60Hz would require reducing the resolution to 1080p. This downscaled resolution may not satisfy the high expectations of Ultra HD displays and can result in a subpar visual experience.
Furthermore, the lack of support for deep color and high dynamic range (HDR) further diminishes the image quality potential of HDMI 1.4. Deep color allows for a wider range of colors, while HDR enhances contrast and color accuracy. Without these features, the visual depth and richness of 4K content may be compromised.
In summary, while HDMI 1.4 can technically deliver 4K resolution, its limitations in bandwidth, chroma subsampling, and lack of support for deep color and HDR ultimately result in compromises in image quality when striving for 4K at 60Hz.
