I believe the act of removing the dvi connector automatically turns it off. Turn the 2nd monitor off and then simply remove the DVI cable from your iMac. Your screen will go blue or change for a second and then come back in. There will only be 1 monitor listed in the display preferences, your iMac monitor. I don't think you can turn if off without doing so unless someone has a hack. At least as far as I know.
