Is this a feature and how would I find it?

Basically I have 5 monitors and 1 TV connected to my system in my office. When I watch a movie on the TV I would like to turn the other monitors off and have everything stay where it was. Currently when I turn the monitors off apps and windows get shuffled around. To work around this I'm currently using the monitor fading feature set to 95% which is amazing during the daytime hours. At night though it would be nice to shut off the monitors to go completely black.
