HDMI: The right choice for HDTV

In the present times there are so many different kinds of options available to us to connect our HD display units such as the DVI, VGA and HDMI that it becomes very difficult to make the right choice and get the best possible quality of picture on our HDTV or computer monitor. Firstly, we need to understand why so many options are made available in the first place and why there is so much competition in the market over something as small as a cable connector.  A lot of effort goes in creating and then making your product the market standard. It means besides the requirement of a lot of investment there are product specific issues like cost, backwards compatibility, HDCP piracy protection etc. that need to be addressed for creating a product that becomes widely accepted as a standard. After so much effort anyone would want their product to win the market competition. Our job is to figure out which product suits best our requirements of working well with an HD display.

HDMI transmits the source signal in digital form which helps not only in the preservation of high quality image data but also prevent the copying of the High-Resolution digital material serving as an anti-piracy application with the use of HDCP (High Resolution Digital Content Protection). The presence of content duplicity protection gives content providers security so that they do not hesitate in the use of high quality performance data.
In the PC industry the aged VGA connector was replaced by the DVI cable that was very useful as it could support both the digital and analog signals in the single wire that was connected from the graphics card to the display. That was a major improvement of the DVI over the analog transmitting VGA cable that could not support the digital LCD displays. But even the DVI cable is not a good option to connect your HDTV to your set-top boxes even when the manufacturers provide an input for DVI. This is because the DVI connection takes too much space and does not support audio formats. The HDMI though very similar in features contains lot of improvements over the standard DVI cable. These include the eight channel of high resolution audio transmission that removes the need to connect wires for both audio and video to and from every device. A single wire serial bus can also aid in carrying remote control signals.

Overall the HDMI comes with stricter technical standards and the HDCP content protection that makes it better for use than the DVI. Not only this HDMI is backed by various top industry electronics manufacturers and the movie content providers because of the HDCP copy protection. This is why all new HD-DVD players and set-top boxes, blu-ray players, all have an HDMI input. Getting an HDMI cable will not only let you view the highest resolution image (1080p) possible on your HDTV, but it will also ensure compatibility with all future electronic digital High Resolution display devices.
