So I have a MacPro with 2 DVI ports. I have a HP HD Monitor that only uses standard displayport (Not Mini) I got a DVI to Displayport cable, Plugged it up and got nothing. Am I missing something? I see the the dvi side of the cable doesn't fully match my DVI to VGA adapter that I previously had in there. Is there another way I can do this? The monitor is not reading the signals obviously.
