What is a HDMI cable ?

Question

Im looking for a used xbox360 on amazon.com and i found one but it says that it has no HDMI cable so could you tell what it is.

Answer 1

It means a High Definition Multimedia Interface Cable.

It allows you to play your X-Box games in high definition but it is not required

Your T.V must be high definition enabled though.

Answer 2

HDMI gives you better picture quality its used instead of the red white yellow a/v cables but it is not needed  

Answer 3

So long as it comes with SOME kind of AV cable, you're fine.  The HDMI is completely optional, and only works if your TV is HD-enabled and has an HDMI port anyway.  If it doesn't have any kind of AV cable, though, you're going to be paying an additional $20 to $30 to buy one so you can hook it up to your TV.
