Turn off Cinema display

I'm looking to get an ADC cinema display to go with my file server which is a G5, and since i'm getting it for a really good price, $10, i'm pretty happy because i have always wanted one. Anyways, i was wondering if there is a way to run off the display without turning off or putting the computer to sleep. My friend has one with his, and the power button, or touch button, on the display puts it to sleep. Since mine is a server, i don't want that to happen, i just want to be able to turn the display on and off as needed while leaving the machine on. Is this possible? Thanks
