I had connected a standard cheap HDMI cable leading to my bluray player and HDTV receiver to was my Philips LCD device. And I've bought 2 of these cables. The difference was huge for me. Black is better represented, bright saturated colors and no formation of small blocks. Who a quality LCD / plasma panel has at home and a cheap HDMI cable uses away neatly image quality. I buy 2 of these cables does not regret so bluray now makes twice as much fun. '
