What HDMI Cable do I need to watch 3D Tv

HDMI or High Definition Multimedia Interface is a cable for varying lengths that are used to connect various digital data sources such as set-top boxes and DVD players to HD compatible display units such as HDTVs and computer monitors. The HDMI cables are an up gradation over the previous counterparts like the VGA, component video or DVI as they can transmit higher resolution images and also audio signals that are supported by the other cables.

There have been many updates of the HDMI cable since their initial release in 2002. All of them have been used for high resolution transmission as all support image resolution of up to 1080p.

HDMI is also backwards compatible with DVI.

The question that comes to our mind is which version of HDMI will be suitable for viewing 3D motion pictures of connecting 3D gaming devices. The answer for that is the latest version of the HDMI cable, HDMI 1.4, which enables 3D sources such as PSPs to communicate with the 3D display devices through the HDMI link. This development can help bringing the 3D technology to everyone’s homes.
