cables each with its own specifications and capabilities. Which HDMI cable
is right for you depends on what features you need. Here we’ll help you
make sense of the various specifications so that you get the cable you need
without opting for higher priced alternatives that are of no additional
benefit for your particular situation.

First, a bit of good news. All HDMI cables are backward compatible. That is
to say that a current cable will do anything that its predecessors did but

who are upgrading equipment. HDMI was initially released in 2002 but has
only recently gained such prominence. As new electronic products have added
capabilities, they’ve increased the requirements for new cables,
particularly in terms of increased bandwidth. In practical terms, the
current HDMI specification is version 1.3 and it’s generally available on
all current HDMI equipment and current HDMI cables are of that standard.
There are additional specifications labeled 1.3a and 1.3b but the
designations aren’t relevant to consumers. The more advanced standard for
HDMI 1.4 has been recently released and its availability will occur
