These specs tie into the HDMI connection standards, which is why you might see some Category 3 cables listed as HDMI 2.0 cables and some Category 3 (8K) cables listed as HDMI 2.1. Basically, if you have a 4K console with an HDMI 2.0 output and a 4K HDR TV with an HDMI 2.0 input, then you’re going to need a Category 3 cable running between them, or you run the risk of only getting 4K at 30Hz. With a bandwidth of 48 Gb/s, it supports high-resolution formats like 8K at 60 Hz, 4K at 120 Hz, and uncompressed video resolutions, all while delivering stunning Dynamic HDR and 3D visuals. Several versions of HDMI have been developed and deployed since the initial release of the technology, occasionally introducing new connectors with smaller form factors, but all versions still use the same basic pinout and are compatible with all connector types and cables. Other than improved audio and video capacity, performance, resolution and color spaces, newer versions have optional advanced features such as 3D, Ethernet data connection, and CEC extensions.

HDMI Version 1.0 was the first release of the HDMI specification and was announced in 2002. It supports a maximum data rate of 4.95 Gbit/s and a resolution of up to 1920x1080p at 60 Hz. Most newer copper HDMI cables reach around 15 to 25 ft (5 to 7.5 m). HDMI cables made with fiber optic can reach much farther. On average, fiber optic HDMI cables can reach around 50 to 200 ft (15 to 60 m). HDMI:: Manufacturer:: HDMI Alt Mode for USB Type-C Connector". www.hdmi.org.
