To use or not to use HMDI cables has nothing to do with data transfer capabilities of the cables in question. It’s limited to handshaking and that dam acronym I can’t remember….KEN???

Michael is correct, if you want to hear the HD audio codecs (uncompressed PCM), you will need to use either HDMI or the player’s (if equipped) multi channel analogue outputs.

As far as video goes, your display will have to have DVI or HDMI (720P, 1080i or 1080P)
