For beginners, let us define HDMI – this stands for High Definition Multimedia Interface, and is used for transferring information and data, whether video or audio to an HDMI-compatible gadget that shows that transferred information, such as TV, projector, or computer.

HDMI 1.3 was introduced first on the 22nd of June, 2006, designed for the bandwidth of 340 MHz or 10.2 Gbit/s, and had developed into different versions such as 1.3a, 1.3b, and so on. It started the increased color and different audio and video sync. It is capable with 2 kinds of cable – Category 1 to 2 and has its own Mini connector for different portable devices.

An upgrade is the version HDMI 1.4, and being a newer version means the improvement of the capabilities of the previous one. The first noticeable enhancement is a higher resolution of 4096×2160. It also supports 3D, all the available resolution that draws alongside the animations of the century. Another big improvement is the audio return channel that allows the audio to run in both ways. It has an Ethernet channel that helps improve communication and transfer of data.

Eventhough HDMI 1.4 proves to be superior to 1.3, it still retains its roots from the previous model. Cables used 1.3 can still be used in 1.4.
