HDMI 2.1: what is a 48G cable?
This is about defining a new specification of a HDMI cable's speed, with so-called 48G cables (for now just a working title) offering 48Gbps bandwidth for sending uncompressed 8K video, with HDR, over a HDMI 2.1 cable.
So why do we need a 48G-rated cable? "Because we're carrying so much data now – we've gone from 18Gbps in HDMI 2.0 to 48Gbps in HDMI 2.1," says Park. "Today we have 'standard speed' and 'high speed' HDMI cables, and 48G will be related to that."
Ditto the compliance tests that each HDMI 2.1 cable will have to pass in order to be labelled as such. Backwards-compatible with earlier versions of the HDMI specification, and able to be used with existing HDMI devices.
