What Do Integrators Need to Know about HDMI 2.0?

For starters: Not all HDMI 2.0 devices are created equal.

I had a chance to connect recently with Marques Girardelli, manager of electronics platforms at Planar and Leyard, for a discussion on connectivity trends. We started with the basics: HDMI and the newest standard, HDMI 2.0.

The HDMI 2.0 specification was released in 2013 and consumer electronics manufacturers have slowly been migrating their platforms to support many of the new features included in the standard. We know there is confusion in the marketplace about what it means to be HDMI 2.0 compliant.

As a refresher, some of the new features in HDMI 2.0 are:

•  4K @ 60Hz resolution
•  4:2:0 color subsampling
•  Rec. 2020 (or BT.2020) colorimetry
•  21:9 aspect ratio
•  32 channel audio
•  HDR support (as of HDMI 2.0a)
•  HDCP 2.2 support

“In practice,” commented Girardelli, “very few devices support all of these new features, so it’s important to understand exactly what functionality is implemented in a particular product.”

Sadly, asking “does this product support HDMI 2.0” won’t elicit a very meaningful answer.

As an example, consider two different HDMI 2.0-compliant products:

•  Product A: 1080p max resolution, 2 channel audio, 8-bit max (no Deep Color), HDCP 1.x
•  Product B: 4K @ 60Hz max resolution, 8 channel audio, 12-bit max, HDCP 1.x/2.2

In each case, the vendor may advertise the product as being HDMI 2.0 compliant, even though the supported feature set is remarkably different. In general, we find that when someone is asking if a product is HDMI 2.0 compliant, they’re really asking if 4K @ 60Hz is supported.

What are you finding as you try to meet customer requests for HDMI?
