    You often see these. I've used them as doorstops. They lack the four analog pins that would make DVI-I, and therefore have no obvious way to work.

    Why do they exist?

    This thread suggests they're simply a con, an ebay ploy to sell nonfunctioning, technically impossible bits of plastic for profit. My own experience doesn't line up with that, because I have - from way back in the day - genuine ATi-branded ones which clearly were made to work in a specific context.

    I just can't fathom what it would be.

    How much power would it take to run a video DAC? Because if I remember correctly; DVI-D does have a +5V line used for monitor sense and control in it.

    Beyond that; DVI-D doesn't appear to have any analog data output paths on it to repurpose other pins into RGB Analog transmission.
