HDMI cable specifications are regularly revised and improvements are made with each subsequent version. Extra features are added and support enabled for a range of new technologies, which means that HDMI cables are always able to keep up with the latest products.
An example of this is HDMI 1.4 cables, which unlike previous versions are able to offer support for 3D TV applications. Whilst HDMI 1.4 already offered support for several stereoscopic 3D formats, the newer version, HDMI 1.4a (released on March 2010), added additional mandatory 3D formats for broadcast, film and game content.
What revisions such as this mean is that HDMI is able to evolve alongside new, innovative and increasingly complex TV, game and home entertainment formats. There are a huge number of products being released all the time and at present HDMI is able to support all of them. This range of support is expected to continue into the future, but HDMI specifications will be revised again in line with technological advancements.
From the consumers’ perspective, it means that if you buy HDMI 1.4 cables, there will be no need to replace your cables for years to come.
