Mansell360 wrote Well what no one else has sad is do youhave an HDMI port on the back of your xbox as some models do not. if you do get an HDMI cable to play in full HD but if you dont the red, green and blue cables are fine and are also HD just make sure your lead is set to HD where you have the TV or HD option on te lead. hope this helps

Oblenator wrote So I've decided to upgrade from my small TV to something a little bigger and more HD. The only reason I am buying it is for 360 gaming and I'm a tad confused about getting it set up in 1080p HD.
I've heard that you need to buy a cable for it but my normal Xbox Video and Audio cable has Green, Blue and Red cables coming from it in addition to the White, Yellow and Red cables as well. Are these HD cables or something else? And if they are something else what are they?
Also, the full name of the cable I may need to buy would be great help if you could supply it.

Thanks.

I think I have it however I'm not sure what it looks like. I have a USB port looking thing next to my Audio/Video cable, is this it?
