So my question is regarding HDMI cable quality. I read things on the packaging such as 120hz, 10.2 ghps speed rating, 12 bit, and for 1080p and up. I found the salesman at my local electronics shop really pushing for the expensive 120 dollar HDMI cable. it is a digital signal so wouldn't the 39$ cable do just as good of a job? even though it states up to 720p? I feel as if it is a scam. I know cable quality would matter with analog signals. but if an HDMI cable is already digital is my eye and ears going to notice a difference? I hope I explained myself clear enough.
