    Can anyone tell me how to turn off my secondary Apple cinema display monitor? I'm using a 30" matte ACD as my main and a 23" ACD matte screen as my secondary. The power button on the 30" turns off that monitor however the power button on the 23" brings up a window asking if I want to shut down, sleep, or restart. I'm wanting to have Netflix play full screen on the 30" and be able to disable the secondary monitor while I do this. Any tips?
