Dual-video cards has been supported as far back as Win98
(or was it Win98SE.) But back in those early days, many
users had lamer PCI/VGA cards. While a properly implemented
PCI/VGA card is fully address-reconfigurable, a lot of older
PCI VGA-cards sat on unrelocatable ISA port addresses (anyone
remember the old S3/86x/96x series? It sat on the COM3 or
COM4 port address, killing it if you had a serial port
configured to use that IO-port address.)
....
In the olden, MS-DOS days, programmers used 'dual-display'
DOS-boxes...the CGA, Hercules, and EGA/VGA cards all used
separate, non-overlapping base-adresses. Which means you
could install 2 of those cards (example, CGA + VGA, Hercules
+ EGA, etc.) Applications like my favorite Borland Turbo
C++ 3.0 supported dual-display!
