Make sure "DPMS" is enabled in your X server.
(DPMS is the power save system for monitors)

Then, in whatever file you use to start x programs, add the following:

    xset dpms <standby> <suspend> <off>

to manually shut down the display, use

    xset dpms force off

(read 'man xset')

That's what I've heard too, so I'm doing what you're trying to do.
