iPC Monitor Shutdown

Have a client who installed an iPC. For video timing, security and other reasons, they leave their FOH on 24/7. Is there any way to shut the touchscreens off and leave the console on short of unplugging the powercord in the back of the console feeding the touchscreens? The power buttons on the side of the iPC don't seem to have any effect on the monitors. Thanks.
