Hdmi versions issues upgrade#

While taking this step should make your home theater wiring 'future proof' for the next few years, there is whole new generation of HDMI coming along within a few years (see below), and this will also require a new generation of HDMI cables.

So if you have, or plan to, upgrade your home theater to fully support 4K/UHD, I strongly encourage you to use HDMI cables that carry the Premium Certification sticker. HDMI cables that pass these certification tests are allowed to be labelled as 'Premium Certified' HDMI high speed cables and carry the official certification label as shown below.

More information on the Premium High Speed HDMI Cable Certification program can be found HERE. In 2016 the HDMI Licensing Organization came out with standards, including testing requirements, for certifying cables to support the maximum HDMI 2.0 bandwidth requirements. or more) from the 'equipment rack' when you take into account running the cable, from the equipment rack to the wall, up the inside of the wall, above the room's ceiling, and then down to the projector. This can be a real problem since home theater video projectors are frequently ceiling mounted and located some distance (e.g., 25 ft. When moving to HDMI 2.0 the fact is that most 'high speed' HDMI cables simply cannot pass the highest data rates allowed by the HDMI 2.0 standard when the cable is more than a few feet long. HDMI 2.0 allows for data rates up to 18 Gbps while HDMI 1.4 max'ed out at 10.2 Gbps. The other 'component' in the signal distribution chain that has been a issue, especially for home theater owners that are using a 4K/UHD projector, has been the HDMI cables. Many of those issues have been slowly worked out to the point that most currently available hardware seems to be compatible, but there are still certain makes and models of devices that when connected to other HDMI 2.0 equipped devices may have issues. The introduction and transition from HDMI 1.4 to HDMI 2.0, along with the transition to HDCP 2.2 and its copyright protection mechanisms, resulted in a number of compatibility issues among 4K/UHD source devices, displays and intermediate devices, such as audio/video receivers (AVRs). There were subsequent enhancements/extensions (e.g., support for High Dynamic Range) to that standard in the form of HDMI version 2.0a. It's now been more than three years since the HDMI 2.0 standard was released and more than 2 years since the first 4K/UHD consumer products showed up with HDMI 2.0 inputs/outputs.
