Flat panel displays with analog VGA connector work on any VGA connector.
If you want DVI, there's little choice. There's a PCI Radeon for the Macintosh market that has
DVI, and a somewhat outdated Matrox card.
The sad part of the story is that many of those chipset integrated VGA units technically
can provide DVI-out - all SiS chipsets can if outfitted with a SiS 301 companion chip, VIA has
versions w/ DVI output, Intel's 8xx also have it. It's just not being done on those all-in-one
boards and SFF boxes. Yet.
