Bootcamp Windows 7 Sleep Display question?

Hey guys,

I have a 27" iMac running Boot Camp with both Mac OS X Mountain Lion and Windows 7 Ultimate.

When I'm in Windows, is there a way that I can turn off the display? Currently if I press the power button on the back of the machine it automatically shuts down Windows. Is there a way I can configure it so that it only turns off the display as opposed to the hard drive and everything else? Or is there another/better way of accomplishing this? Or any other way to turn off the display only?

Thanks!
