Why are HDMI cables so popular today? How are they any different from a DVI cable? There is only one way to find out. Here is a look at some of the major differences between the two kinds of cables.
The Digital Visual Interface was brought into the market in 1999. Its main purpose was to deliver uncompressed digital video data to a display medium. In the past they were used only for computer monitors but are now used for televisions as well. There is confusion about DVI cables because of the connectors that are used for different functionalities. There are three main connection types; DVI-D, which is digital, DVI-A for analogue and DVI-I for both digital and analogue.
High Definition Media Interface was introduced in 2002. HDMI is a totally digital audio and video interface that sends uncompressed data just as DVI. The difference being that HDMI cables have the capacity to carry audio and video signals while incorporating a Digital Rights Management Technology.
What is the difference?
HDMI is the successor to DVI technologies. HDMI supports both digital audio and video, where as DVI can only carry digital video. HDMI also includes content protection which is called High Definition Content Protection. HDMI cables do not pose any length restrictions. HDMI cables do not need to be long to transmit data well.
If an HD display source has a DVI connection then it will need another cable for audio support. This is not at all necessary when using HDMI cables.
Therefore, it is always wise to use an HDMI connection as all electronic display manufacturers are employing HD technology.
