Only devices (TVs, Blue Ray player, ect ...) Deferred according to the HDMI standard 1.3 or 1.4, HDMI connecting cables, do not change them!
Since an HDMI cable specified in the standard 1.4 is wired in the same way that a model 1.3 (19 pines cord are physically connected in the same way for both standards) and as the bandwidth and maximum frequencies are strictly the same for the standard 1.3 and 1.4, this means that any manufacturer can legally declare an old cord HDMI 1.3 as to the standard 1.4.
The difference in quality between a basic HDMI cord and a good HDMI cable is the cable conductors of the section that justifies a more or less significant loss per meter length at the frequency of the signal, which makes for an HDMI cord short length is less than 5 meters, a cheap HDMI cable will give the same functionality and the same quality of image and sound or 3D effect if necessary!
The best existing cable AWG24 nome, he has single-stranded conductors and a PTFE Teflon insulation, it can transmit at higher frequencies of gigahertz with rigorous integrity phase to the clock signal, which is important, it remains the HDMI cable the most powerful of the market regardless of the transmission format (1.3 or 1.4).
Too bad the AWG24 or other type of cable specification is not indicated in the specifications of the HDMI cord, nor in most other competing products elsewhere!
So to summarize, the differences in quality of an HDMI cord, this is the section that consists of drivers with its cable insulation and shielding and mechanical quality and solidity of its connectors and especially the strength of the cable connections on connectors that must not tear during handling.
