This DVA hookup has a full set of prongs whereas the computer that I'm plugging into has 9 sets, space, 9 more sets and then the long prong.
You can't hook up a digital source to an analog monitor. Are you sure you don't have a DVI-I port as well? I have never seen a computer that only had DVI-D and no VGA. Thats beyond strange.
There ARE GPU's that would work with the adapter posted BUT they have to support outputting the Analog signal on the digital pins in the driver. the VAST majority don't. but yours might since its so strange.
