Difference between HDMI and DVI-I?

[ericarzou81]

I'm just wondering if there is a difference between the two because since DVI-I carries analog as well as digital it should carry audio just like HDMI does. Is their any real difference between the two? Thanks.

The video signal is the same, both digital. Some DVI connections will carry audio. I had my HDTV connected from the DVI-D on my GTX 570 EVGA SSC card to the HDMI on the Samsung TV awhile back. I could get sound via the TV speakers.

Many TV's run a bunch of post processing tweaks to an HDMI signal . Maybe some monitors too

Basically that will annoy you so use DVI , unless you need sound via the cable too .

The electrical interface between Single-Link DVI-D and HDMI is identical. The logical interface for the DDC is also identical. The logical interface for HDMI's data transport is a superset of Single-Link DVI-D.

Dual-Link DVI-D has twice as many TMDS pairs as Single-Link DVI-D and HDMI.

DVI-I (both Single and Dual link) has additional pinouts for analogue signalling that is electrically identical to VGA.
