Re: On the GTX 470 mini-HDMI
I know what a mini hdmi is and that is what is on gtx 4XX and gtx 5xx cards. Just the revision of HDMI is different. most gtx 4xx cards are 1.3a and gtx 5xx cards are 1.4. The 1.4 revision will only come in handy for 3dtv's as 1.3a handles everything else. I am not sure what micro hdmi is but I would guess it's smaller than mini if it exists. As for sound, your video card is supplying the sound when hooked up to a HDTV via HDMI. Like everyone else said, make sure your nvidia high def sound drivers are installed before connecting the pc to the tv. Your XFI card is not needed for HDTV connection although I would keep it installed if you are going to constantly switching between pc monitor and HDTV pc use. When set up properly, Nvidia control panel or windows (not sure which one) will switch between using the graphics card via hdmi for hdtv and sound card for regular pc use when either is needed. Please read the other posts too. They have more detailed info.
