How to disable a laptop screen?

Windows 7, right clicking the desktop and selecting screen resolution. I selected the laptop screen and under "Multiple Displays" selected "Disconnect this display", so now I have it showing on only 1 external monitor, nothing else. At this point I thought I should be able to extend to the other monitor, but when I do it gives me unable to save display settings.
