[comp.windows.ms] SPECIAL Multimode 1024 X 768 video card for the PC???

I'm curious if there are any video cards that do the following:

	- Support 1024 X 768 X 16/256 mode
	- Support CGA, EGA, and VGA, *without* having to have a
	  multi-sync monitor.

In short, I have a 1K x 768 48kHz monitor that does not multi-sync, and I
would like to find a card to drive it that *also* supports the other
standard modes by simply `upconverting' the video rate for the slower
lower-res modes.

In theory, such a card could accomplish this through line/pixel doubling or
through using a smaller chunk of video memory and scanning it out
at 48 kHz.  Yes, the actual video for the low-res modes would occupy a
smaller area on the screen (probably in the upper left hand corner), but
I can live with this.  I plan on using the monitor/card in hi-res mode
most of the time, but I would like to be able to run ega/cga/what-have-you
mode for applications that require it.  And no, I'd prefer not to buy
a new multi-sync monitor.

Any pointers/info would be greatly appreciated!
