12Ghosts ScrSavMan

Automate screen saver settings by shortcut, batch file, or scheduling. Change screen saver, stop it with a scheduler, start with password protection, set time-out (within seconds!), enable/disable screen saver, set/reset password protection, enter standby mode, change wallpaper.

This tool supports the Nutek power management standard, that turns off monitor power when a totally blank screen is detected.
