You can alter the sync polarities and whatnot on many cards depending
on when it was made. In the mid-late 90s manufacturers were adding
the ability. There are also adapters that can be built. Or you can
fiddle w/the firmware or graphics chip.
At least one firm, Mirage, for years made a regular business of
supporting fixed-frequency monitors on PC gear. Their regular web
site looks as if it's rotting away, but archive.org has plenty of old
pages.
I used their VGA cards (both ISA and PCI) with HP (Sony) workstation
nonitors, and earlier with Daisy monitors. They worked very well,
and compared to the quality and prices of multisync PC monitors, were
a bargain.
Mostly, cards were commodity with different BIOS code. I think I may
still have one based on a Tseng 6000 PCI card.
