Hi
Im running a Gigabyte 780g MB - You can only have HDMI and VGA or DVI and VGA. You can not have DVI and HDMI output running together. If I remember correctly you make this selection in BIOS.
It may be worth looking to see if the Nvidia 8200 integrated boards can achieve this. If they cant then I think you are stuck with the options you have already listed
