IMac – Remotely working on iMac, but with screen darkened

displayimacremote control

I have my main iMac in my kids room (little house, alas) and often I have to work late at night; I'd like to connect from my MacBook to the iMac keeping the screen black, as in sleep mode. Is there any sort of magic to achieve this? What if I plug a Mini DisplayPort cable? Will it exclude the monitor?
Thanks,
Guido

You might be overlooking a simpler solution: throw a sheet/blanket/whatever over the display before you walk out of the room.
