A HDMI is a high-definition multimedia interface. It supports 8 channels of 24-bit uncompressed audio 192kHz and video resolution of 4096 by 2160 pixels


DVI and HDMI both have 19 pins, so it is hard to recognize from the plugs some time. In addition, DRM or copy protection within a computer is enforced by high-bandwidth digital content protection (HDCP) for DVI and HDMI interfaces.  

DVI existed before HDMI and is available on more Computer.The benefit of the DVI cable is less expensive than HDMI equivalents.


As said above, I guess most user would have DVI-D cable nowadays. So here mainly talking about the difference between HDMI cable and DVI-D cable. 

One of the most notable differences between HDMI and DVI-D is only HDMI can support audio. DVI-D is strictly a video format and cannot transmit any kind of audio. For converting an HDMI signal to DVI-D will need another kinds of cable, like component audio or TOSLINK. The other major difference between the two is HDMI supports a form of digital copyright protection called High Definition Content Protection (HDCP). This can make copying signals via HDMI impossible. DVI-D does not support any kind of similar copyright control method.

Choose right video and audio cable for you home to enhance your LCD or HDTV performance. There will be perfect to watch NHL games, movies or other entertainment.
