HDMI 2.0 vs 1.4: What’s the difference?

HDMI 2.0 was announced as a standard in late 2013. It got a lot of people confused, wondering if they suddenly needed to throw away their TVs in order to get on this latest tech trend.

As far as tech advancements go, HDMI 2.0 is a pretty friendly one. It’s as much a standard of software as hardware, and cables designed for HDMI 1.4 systems will work just fine with new HDMI 2.0 devices.

What you need to make sure is that both ends of your entertainment chain – your TV and Blu-ray player, for example – support the standard. It’ll mean they’re geared up for the new standards we’ll dig into shortly. Some previously HDMI 1.4 hardware needs nothing more than a firmware update.

HDMI 2.0 is a reimagining of the interchange between your bits of home entertainment gear, one that factors in the immense amount of data required to get high-quality audio and video to something like a 4K 3D-capable TV.

HDMI 2.0 itself isn’t really about resolution, though, but bandwidth. More bandwidth is what makes all of its new standards possible. HDMI 2.0 systems can transfer data at up to 18Gbps, up from 10.2Gbps in HDMI 1.4.

In terms we’re all more likely to get on with, 18Gbps is 2,250MB a second. For a little more context, normal Blu-rays max out at 54Mbps, or 6.75MB per second. The HDMI pipe is wider than a dual carriageway.
