What Is HDMI 2.1, And What Are Its Benefits?

In short, HDMI 2.1 is the latest version of HDMI that distinguishes itself by being capable of transmitting an impressive bandwidth of 48 Gbps (GigaBits) in the cable. This is a considerable improvement from the previous 2.0 cables, which carry 18 Gbps. In general, bandwidth determines the max amount of data the signal in the cable can send. The higher the resolution and frame rate, the more data is needed.
