example:

laptop has external screen connected it. external screen primary screen.

when screen disconnected laptop becomes primary if external screen reconnected. there way trick windows thinking monitor there? , not revert laptop screen primary screen?

the way thinking work kind of low level driver? wouldnt have clue start

for work, had same situation -- on embedded pc, needed second monitor available.

i put considerable amount of time researching it, wasn't able find solution other hardware.

if have vga port (or dvi-i), you're in luck. can find directions on how fake couple resistors (here's 1 set of directions).

ultimately, project, had dvi-d port available. had come microcontroller solution send "fake" monitor signals (via i2c) pc. can't go more specific detail that, unfortunately.
