Need a little help. I just order a Samsung HL-S5088 DLP 50in.The sales persons told me ,when I order my HDMI Cables to make sure that they are something made with Or called (DIALECTRIC) he said that is what I have to use. The man at the cable site told me that the 6 ft cables that I need are good they have made with copper. The site I orderd from is called (MonoPrice.com) has anyone done any bussenes with them,all remarks will be welcomed.Simply put is ther any truth in what type HDMI cable you use. Thanks Andy..
