There is only one qualification to offer here: with HDMI 1.4 the spec introduced a new optional "Ethernet and Audio Return Channel" feature, which does require slight changes in cable architecture. They have the same conductors, in the same configuration, wired to the connector in the same manner. The basic characteristics of standard HDMI cables have not changed from one spec version to another. Device compatibility is a complicated subject and is really outside our area of expertise, but when it comes to cables, we can give some reassurance. With all these spec versions around, and equipment and cables having been designed and tested in accordance with one version or another of the spec, it's natural that people worry about the compatibility of equipment and cables. What about 1.4? Well, we are working on cables which will implement the 1.4 Ethernet channel but, as will be explained further below, a cable which complies with 1.3 (or, for that matter, any prior spec version) is also compliant with 1.4. Our Belden HDMI cables have been tested under main spec version 1.3a, CTS version 1.3b (and, in the case of our Series-1 Category 1 approval, CTS version 1.3b1). As you can see, there is no such thing as "HDMI 1.3b." But the Compliance Test Spec does have a 1.3b version, as well as a 1.3c version (testing for cables was unaffected by these minor CTS revisions, except that 1.3c adds new criteria for "active" cables). We are sometimes asked whether our cable is 1.3a or 1.3b compliant. That's unfortunate, because it's in the CTS that the details of compliance testing are contained, and there can be some significance to that.
For some reason, however, HDMI, LLC does not authorize release of the Compliance Test Specification to the general public.

The HDMI Licensing authority ordinarily allows anyone to download a copy of the current version of the main HDMI spec document from its site at. HDMI Compliance Testing Specifications:.Additionally, however, some references to specs are not to the principal HDMI spec document, but to the "Compliance Testing Specification" document, and there have been six versions of that document. What Are The Spec Versions?Īt this writing (February 2010) there have been six versions of the principal HDMI spec document. Is it the latest spec version? Will it support all the features of the devices it's hooked to? Most of the fears and doubts associated with this question are unfounded, but there are some interesting issues with regard to HDMI spec version, and we'll sort those out here. Many people are worried, when buying HDMI cable, about the spec version of the cable in question. We will be updating this information before the end of 2015 to include HDMI 2.0 and related topics. It's safe to assume, though, that to get the content to and from the wireless transmitter and receivers, you'll still need HDCP 2.2 on your receiver/source and display (so the whole chain is 2.2).What Do These HDMI Spec Versions (1.2, 1.3, 1.3a, 1.4, etc.) Mean to my HDMI cable? Note: this article is a bit out of date. Since wireless 4K has only recently been announced at all, this isn't an immediate issue. You may also "see" HDCP 2.2 in new wireless gear, like those with Miracast or WirelessHD.
#Hdmi versions 1080p#
As in, your current Blu-ray player will send 1080p to a 2.2-enabled receiver, or to a 4K TV, with no issues. Your current devices will work fine with new HDCP 2.2 devices, presuming you're not trying to send content with 2.2. For the time being, as we've said, it's not a big deal if you're planning on sticking with 1080p. At least, not on a product that wasn't designed with at least some idea about 2.2.
#Hdmi versions upgrade#
There's no firmware upgrade that will get 2.2 working on a non-2.2 product. Your current gear is not 2.2-upgradable, but that's probably OK
Once we start seeing more widely available 4K content, it will be more of an issue.
#Hdmi versions tv#
So for now anyone with (or buying) a non-4K 1080p TV doesn't need to worry. HDCP 2.2 is essentially about UltraHD 4K copy protection. You don't need to ditch your gear just yet.
