I've been looking for a hdmi->vga adapter for a different purpose but also to get one for my pi*. They all seem to get mixed reviews /but/ I've used many dvi->vga converters without even thinking about the fact they must be doing a DA conversion. They just worked. Supposedly, hdmi->dvi can adapted with a cable that maps the matching pins, so shouldn't hdmi->dvi->vga ``just work''? Has anybody tried it? ('course the adapter stack will be as big as the pi...)
My understanding is that while dvi has pins for analog signal few video cards actually output on those pins.

*installed cable for projection system is vga. For mi py hdmi->dvi would probably take care of all my needs, but it exists to play with).
