Yes it is possible as the chipset supports it. Now your motherboard manufacturer or system builder may have limited this feature.

Thanks BigThor for the link.
i understood that dual-head is available, but an electrical adaptater/converter have to be used to convert sDVO signal in signal that CRT or Flat panel can manage.
I hope the provider of the embedded motherboard put the correct component which avoid to use ADD2 or MEC extension card...
That is usually when you have only one video port. In your case as you have to VGA ports you should be able to get dual display with them.
