With dvi and hdmi, it's digital all the way from your card to the monitor, nothing is recalculated. The luminence and colour of each pixel is sent directly from the card and is directly interpreted and represented by the display.

DVI and HDMI, along with displayport, are the best way to connect your panels at the moment. There are absolutely no discernable quality differences between the three. HDMI also carries audio information, but unless you're outputting to a TV or decoder, it's a moot point.

With a dsub (VGA) connection the digital from the card has to be converted to RGB (of which each colour has 256 possible levels). Basically, it's possible that some of the colour accuracy is scrubbed in this process, and it introduces latency (although I don't think it's measurable...).

On my TV I can't tell the difference between VGA and HDMI I haven't tried DVI because I don't have a DVI out on my PC and I don't have a DVI cable but I assume it's the same story with it.

HDMI does have sound output though. VGA and AFAIK DVI doesn't.

With HDMI it transmits audio and video. However it can transmit 8 Channel uncompressed PCM, where optical can only do 2 Channel Uncompressed PCM. So if you hook your PC upto a 5.1/7.1 then HDMI is the way to go.

A cool tidbit is you can use DVI and hook it up to your Monitor for video, and have the HDMI go out to an audio receiver.

Correct.

I'm using VGA after my DVI port on my monitor died (weird), and now whenever i tab out of games, I get an ever-so-slight flickering on my screen. Like the words are vibrating.
