Here's a solution that might help.
In the screensaver properties, there should be a setting to turn off the monitor. Set that up, then set it up to come on after 30 seconds of inactivity, or 1 minute, or whatever is comfortable. Now, you will get the screen to turn off. The only problem is when you're watching a movie you have to disable it. I havent tried this, but see no reason why it shouldn't work.
