Green blue and red jacks on dvd player.

I have a DVD player that has those color for rca jacks to go out. I also have them on the tv to come in. what are they for and what are they called?

 

there called component cables

http://en.wikipedia.org/wiki/Component_video

they are used for displaying the image

 

they make for a better connection/picture quality

 

true that. much better than component cables (the standard Yellow, White, Red)

 

Does it really make that big of a difference if I use those instead of the regular yellow white and red ones??

 

depends on your TV/set but yes you can tell a difference. its worth the extra few bucks to get the component cables
