HDMI 2.1 WILL BRING A HUGE INCREASE IN BANDWIDTH FROM 18GBPS TO 48GBPS

the difference? OK, let’s say the old HDMI is a cat. The new HDMI is a much faster cat.

It’s not really about speed, though, but volume. A 48Gbps cable is good for 8K video (7680x4320) at 60fps, or 4K at 120fps. So Tokyo shotputting in 8K will be fine, with enough data space to have it in HDR. There’s even room for Dolby Atmos to open up your sound system. And then there’s gaming: those high frame rates are just what VR headset devs have been clamouring for to up the immersion ante.

HDMI 2.1, then – what a difference a 0.1 makes. Though, yes, you are going to need all new AV hardware and cables.
