The answer is a definite YES!
My system is a COMPAQ 486 DX-66 using DOS/WINDOWS 3.11.
I have a MDA (Monochrome Display Adapter) Display with a Hercules Graphics
Card and a built-in VGA (Video Graphics Adapter) on the motherboard with a
monochrome VGA monitor.
Using the DOS MODE command at the "C:\>" prompt as follows:
C:\>mode mono
switches the video to the MDA monitor and:
C:\>mode co80
switches to the VGA - one at a time.
I read that there are a few programs (I think BORLAND C++ is one) that
can actually produce separate output (e.g. text on MDA and an image on
the VGA) on both at the same time (or almost the same time).
I have also heard of high-end 3-D/Virtual Reality systems with two AGP
(Advanced Graphics Processors) - one for the left eye image - and one for
the right. This would use two monitors with crossed Polaroid filters and
a half-silvered mirror (the reflected image is reversed on the monitor so
that they line up); with matching Polaroid glasses. I have also read
of rapidly switching Kerr cells to flash the appropriate eye's image
to the correct eye, using a single monitor. Another possibility is, of
course, a VR headset.
