I have a dell 30 inch display that does not have a VGA slot. I know they dont make a DVI to DVI cable for MBPs. So my question is does anyone know where can I buy the adapter to convert the VGA to DVI so I can connect to my 30 inch screen. I bought the mini DVI to DVI converter thinking it was for the MBP but its only for the MB. Any help would be great thanks.
