A diferença HDMI é o número da versão:
HDMI devices are manufactured to adhere to various versions of the specification, in which each version is given a number and/or letter, such as 1.0, 1.2, or 1.4b. Each subsequent version of the specification uses the same kind of cable but increases the bandwidth and/or capabilities of what can be transmitted over the cable. A product listed as having an HDMI version does not necessarily mean that it will have all of the features that are listed for that version since some HDMI features are optional, such as deep color and xvYCC (which is branded by Sony as "x.v.Color").Note that with the release of the version 1.4 cable, the HDMI Licensing LLC group (which oversees the HDMI standard) will require that any reference to version numbers be removed from all packaging and advertising for the cable. Non-cable HDMI products starting on January 1, 2012 will no longer be allowed to reference the HDMI number and will be required to state which features of the HDMI specification the product supports.
