i didn't know where to post this, so i just posted it here.
i have a samsung lcd tv connected via vga to my laptop and i use it as a second monitor. i am running windows 7.
i accidentally pressed some combination of buttons and it activated a shortcut that brought up a little menu that let me either turn my external monitor off, switch screens, and had 2 other options dealing with my displays, but i can't remember what it was.
i hate running into a shortcut and not remembering what it was.
i think it's a vista command, if not it's a dell command. but if you guys could help me find this, that would be awesome!
