I was at best buy today picking up some stuff for my brother. I got him a blu ray player and picked up a hdmi cable. They recommended since he had a 120hz tv that I get the high speed rated cable. I guess this cable is rated for for 120hz tvs. So I asked the question, since I have a plasma should I be buying the high speed cable? Do any of you know if the double price high speed cable has any noticeable effect on blu ray with a plasma?
