Yea, HDMI is just DVI+audio with a different connector.

Hey people, i've just been thinking, is there any noticeable difference in the quality between VGA cables and DVI cables? Atm I use a VGA cable with my laptop going through to my external monitor and the quality is exceptional, im just wondering, what better is DVI because I might be using two different monitors but one of them only has a VGA input whereas my main monitor has both VGA and DVI and I don't really think I can be bothered spending £30 to get two adaptors...
Please give me your thoughts.

DVI carries a digital signal, so there's no quality loss. VGA carries an analog signal, which is more prone to quality loss/degradation/noise/etc.
For LCDs you want DVI, but for CRTs VGA is the only option.

DVI is digital, so there's no signal degradation, and it looks sharper/better. VGA is analog, so it's prone to signal degradation/noise/etc and looks a little fuzzier.
With LCDs you want DVI, but with CRTs VGA is really the only option.
A DVI cable is only like $5 from reasonable places.

Ahhh but wait, I've just spoke to one of my highly intelligent geeky friends, and he says I can run DVI through the HDMI port on the 40" tv which I plan on doing on odd occasions, so if I bought a DVI to HDMI cable, and a mini-dvi to dvi adaptor, i'd be fairly sorted in the lounge and in my room. How convenient.

Does VGA really degrade over a good quality shielded 3 foot long cable? I doubt it's even noticable. Digital doesn't degrade, it will either work or not work. I think the thing to look at is minimizing conversions to/from analog/digital.
