As far as I can tell HDMI has always been a 21 pin connection anduntill now some of these pins were unused. The information sent down the bale is digital so impedancewould not be an issue - so are HDMI 1.4 cables just a way for cable maufaturers to take more money from us ?? TH reason I ask is I have a 4 year old cable buried in my wall to my new Philips 46PFL9705....Please dont tell me I would need to replace this cable for use with a 3D blu ray player ???
