HDMI capabilities have increased significantly since HDMI was introduced. All generations are backward compatible. However, not all previous HDMI cables can transmit the full 18Gbps of data required to optimize today's HDMI equipment. While there is currently little or no 4K/60 4:4:4 software requiring the full 18Gbps capability of HDMI 2.0, some sources (UHD Blu-ray players) can be set to "up-sample", requiring 18Gbps capability. Up-sampling is often best done in the TV rather than in a source component - but that's your decision. AudioQuest HDMI cables with Exceeds 18 Gbps on the box front are guaranteed to exceed the requirements for all possible HDMI 2.0 data streams.
