If you are using Windows 2003 or XP, you might be able to use powercfg.exe to change the monitor timeout to 1 minute when you want it to be blank (off) and then change it back to a higher figure when you want it on.

See: http://support.microsoft.com/kb/324347

command used in command prompt:
powercfg.exe /change "Home/Office Desk" /monitor-timeout-ac 1

and

powercfg.exe /change "Home/Office Desk" /monitor-timeout-ac 15

The above commands can be executed by VFP.
