Gigabyte 4850 unable to drive dual digital displays?

I bought a Gigabyte 4850 1 GB [url=http://www.newegg.com/Product/Product.aspx?Item=N82E16814125258][/url] (which ironically just got discontinued....) and I also bought an Acer 24'' monitor to go dual with my existing 19'' Acer. This card is different than the standard DVI-DVI-SVIDEO layout on most cards, its DVI-VGA-HDMI (because its passive and meant for an HTPC) When I bought it I foolishly assumed that I'd be able to buy an adapter to convert the HDMI to a DVI port for the other monitor, but I've found that it will EITHER drive one on the HDMI -> DVI -> Monitor port, or on the DVI port but not both. I can plug the other into the VGA port with no problems, but I would REALLY like to have them both digital. I've poked around in the drivers to no avail (this card replaced a 9600GT, and I've owned nVidia cards up til now, so not very familiar with Catalyst) as to how to work this out (if its possible) I was wondering if anyone had any ideas as to how to fix this as I'm at a loss
Thanks!
