Sorry, but that combination will not work in this situation. The Mini DVI connector has an analog signal pin that is used by the Mini DVI to VGA adapter, but by adding the Mini DVI to HDMI adapter you are not feeding this signal through, since it is not needed for HDMI. I am afraid you will have to get the correct Mini DVI to VGA adapter or cable, as this is the only way that this will work.

You rock dood. I appreciate it.
