Offhand there *may* be several ways to power off the monitor. Using the
Operating System interface as described in the MSDN Link (a sequence like
determine if the system supports power management, determine system
suitability for idle, determine display power management capabilities,
power down display) remains the most friendly to other applications.

If your application does not care about other applications, it can likely
1) Disable the display via the ACPI BIOS
2) Power down the display through calls to the ACPI Plug and Play Monitor
Interface
