since HDMI = digital, and VGA = analog and there's more differences wrt the actual signals,
HDMI can NOT produce VGA signals
One should however be able to get VGA resolutions on HDMI, as in 640x480@70Hz, Though, support for displaying these will depend on the monitor or adapters being used.To hook up an analog VGA monitor to a HDMI output of a graphics card you will always need an active adapter.
I'm aware of the protocol and the fact that HDMI protocol is digital, while VGA is really isn't.
My comment was about HDMI as a port. AFAIK, it can switch over and produce VGA signal. From usage perspective, similar to DVI (port), which has even separate physical pins for VGA signal.
But my memory might be spotty on that part, so...
