I was at a store last night picking up my new 52" sony W4100, which has the 120hz processor, and needed some new HDMI cables. The employee told me not to worry that the box for the cable only said 60hz, because it is an advanced high speed cable, and is fully capable of handling the 120hz tv. He did say, however, there could be a difference, but would be extremely minimal, at most. Was I fed a line of BS? The tv looks crystal clear on the right channels, and definitely gives the 120hz smooth transition. It seems ok, but I needed some clarification. It was a monster 800. Should I bring them back for different ones, or are these cables in fact capable of the speed? Any advice is always appreciated!
