    I have an iMac that I keep connected to an LG HDTV via Mini-Displayport to HDMI. I was wondering if there was any way to disable the external monitor without unplugging it? Turning off the TV doesn't actually disable the monitor as I still have the OS thinking it's still on therefore spaces imitates it as being two monitors when its really only one. The main reason I want to disable it is to save my VRAM while I'm playing Source games on Steam.

    Tried SwitchResX, doesn't help. The only way is to unplug my Mini DisplayPort to HDMI adapter every time I want to turn off extended display. Wish Apple would provide a simple "Turn off extended display mode" menu option.
