Is it possible to...

enable dual screen support from only one output..

I saw this happening on one of the Dell SFF (only one DVI output), where there's like a DVI dongle that splits into 2 outputs.. and 2 displays..

Or better, recommend something that will do that over PCI-E 16x

Don't matrox have an external box that does this? This review says laptops, but surely it'd work for DTops as well:

Ahh.. but no worries.. found it on Dell's website for a measly £10.. going to order now.. cheers guys..

Is the two outputs digital or analogue?

I would think the card has to support this configuration and not all of them will. I know the Matrox G200 Quad PCI supports this as they only have two DVI connectors onboard and you split them off to four VGA.
