HDMI vs. DVI: Differences and Similarities

Before continuing further with our discussion on HDMI Cables wholesale, it would be appropriate at this point to bring out the main similarities and differences between these two digital standards. Both are very closely related in that HDMI uses the same digital encoding scheme used by DVI-D in the transport of digital video.
This explains why all that is required to interconnect a DVI device with HDMI-enabled equipment, is a simple DVI-to-HDMI cable adaptor with a DVI-D plug on one end and an HDMI connector on the other. In this case however, digital audio will have to be carried separately since DVI does not support audio over the same interconnect. This would not be the case in an 'all' HDMI-to-HDMI cable, where the digital audio signal is carried along with the digital video over the same cable.
However, out of the different DVI flavors, HDMI is only compatible with DVI-D format. In other words, there's no way to adapt an analog VGA signal to go in through an HDMI connection as is possible with a DVI-I interface.
Other important differences include:
HDMI cable connectors are substantially smaller than the 37.0 mm wide DVI plug.
The DVI standard was originally developed to be used by PCs, while Mini HDMI Adapter was developed by some of the major electronics manufacturers for use in consumer electronic products such as DVD players and digital televisions.
