I have a Microsoft SBS2011 installation that has an interesting issue. The monitor will not go "to sleep" or power down. I have to manually power it down. I have setup a "server Plan" in the power settings in Control Panel to shut down the monitor after 10 minutes, but it does not seem to have any effect. If it reboots, it reverts to high performance. This is becoming an issue because the monitor is in my office and can be seen out of the window and attracts onlookers. Any suggestions? If I leave the monitor off, which I try to do, someone ultimately turns it on to remove a backup tape or some other minor issue.
