4K resolution, on its own, is not enough to guarantee an exceptional viewing experience. To truly take advantage of 4K, you need a sufficient amount of bandwidth to transmit the massive amount of data required for a high-quality image. This is where HDMI 2.0’s increased bandwidth comes into play.
4K HDR, specifically, requires even more bandwidth than standard 4K. HDR (High Dynamic Range) is a technology that allows for a greater range of colors, contrast levels, and brightness. This results in a more lifelike and immersive viewing experience.
Bit Depth and Color Gamut: The Devil’s in the Details
To achieve the full benefits of 4K HDR, you need a connection that can handle a higher bit depth and color gamut. Bit depth refers to the number of bits used to represent each pixel’s color information. A higher bit depth means more precise color representation, resulting in a more accurate and nuanced image.
Color gamut, on the other hand, refers to the range of colors that a display can produce. A wider color gamut allows for more vivid and realistic colors.
HDMI 2.0 supports 10-bit color, which is sufficient for most HDR content. However, some HDR formats, like Dolby Vision, require 12-bit color. In these cases, HDMI 2.0 might not be enough to transmit the full range of colors.
