DVI "is" HDMI. I have a cable with a DVI connector on one end and a HDMI on the other end to connect my laptop to my TV. The only issues are that DVI doesn't carry sound, and doesn't (usually) support HDCP without which your device might refuse to put video out.

(edit) Just looked back and saw you only have a DVI input. You likely won't be able to display anything on your TV from a device with an HDMI output because it won't support HDCP. Sorry.

HDMI is heads and above the best, at least on my lcd tv.

Okay... first, it's probably best that you use 720p on your HDTV, since that seems to be its native resolution.

That said, both component and VGA carry analog signals. Both are capable of HD resolutions, but HDMI - which carries a digital signal - is not subject to signal degradation. That means that HDMI, unlike component and VGA, will give you a pixel-perfect 720p signal.

That's not true for all devices though.  I know it is a problem with the PS3, but I don't know anything about the 360's HDMI out.  DVI will support HDCP every time HDMI does, assuming your DVI display supports HDCP.

Just stick with the component cables. Contrary to popular belief, component will carry 1080P signals as long as your display supports it. That should tell you something about the quality of signal through a decent component cable setup. My Sharp Aquos, for instance, WILL take a 1080P signal over component (which is how my 360 is hooked up) and I'm very happy with it. As mentioned above, stick with 720P for your games and 1080i for movies...

The moral of the story here should be this: any of the three are going to look fine.  Stick with the one that is the most convenient for you setup and avoid switchboxes unless you get a good quality one.

That's not actually an HDTV. It's a "1080i" projection set, which means it has about 540 actual lines of vertical resolution. Still, at least it takes a 720p signal, and it's definitely better than an SDTV.

On that TV, you're not likely to see much of a difference between HDMI and a good set of component cables.

HDMI has the best quality.

hum I4m a die hard anti HDMI for that simple reason http://en.wikipedia.org/wiki/High-bandwidth_Digital_Content_Protection
be against that shit, don't support it.... that's all I have to say lol

HDMI has the best quality.

it depends that is absolutely not a factual truth.. you can find plenty of benchmark proving the opposite... the baby has good specs and an HDMI cable is usually of good quality by default.... but once again I won't support that format because of HDCP being mandatory on it....
