Temporarily disable one monitor for gaming

[cromag_rickmanus]

I'm trying to play Soldier of fortune edition. I read somewhere that the game can conflict with the presence of two monitors and freeze
My question is this: is it possible to disable the second monitor through the comptuer? i.e. not just plain unpluggin it.
I've looked everywhere I can think of. Please help!
Thanks,
John

Switch your 2nd monitor to mirror mode, then just turn it off. When it's on mirror mode it shouldn't cause any additional issues for the OS.
