Back in the old DOS days you could have dual monitors buy installing an old MDA or Hercules mono card (since the mono cards used different memory addresses to the colour cards). Many old programs could display info on the mono screen while running the main program on the colour screen. Fast forward 15 years or so. I now have a modern dual monitor setup. But I have some old DOS apps that I still use from time to time. Is there any way of using my main monitor for the program output as normal, and sending the mono output to my 2nd monitor?
