I imagine ring0 is the only place we're going to get any glory here. If i have some extra spare time in the next few days I'll do some poking around, but I'm no driver guru, so if anyone has any hits I'd appreciate them.
Found some interesting info here
at OSROnline (surprise surprise). It would seem you can send an IOCTL to your monitor to get it to turn off, and windows will not interfere. Of course for the average user this may be a problem if the application
were to crash or whatever, but in this case i believe it would be the perfect solution. Unfortunately i am not even close to the level of experience required for something like this so perhaps someone else *prods f0dder?* is up to the task.
