Here is a simple way to turn off the display in Windows 7. It is not instantaneous, but I can live with it waiting one minute. The script temporarily changes the idle time to 1 minute, waits 65 seconds for the display to turn off, and then changes it back to the original (20 minutes) idle time.
monitor_off.bat:
powercfg -change -monitor-timeout-ac 1 timeout /t 65 powercfg -change -monitor-timeout-ac 20
