This cable works astonishingly well on my xbox 360. I was originally using the cable that came with the console to 1080i but now get 1080p and the is a fair difference for the better...!!
My v+ box from virgin media looks stunning with this cable, other retailer charge £84.99 for the same thing. All hdmi cables need to function fully are to be:
1. Gold plated.
2. 99.99% Oxygen free copper.
3. Both internally and externally shieled against leakage of data.
Hope this helps peeps ;) this cable is a must have...
