How to dim the screen probably depends on the laptop vendor and which NVIDIA card you have as I'd imagine the register that controls the backlight probably isn't always in the same place. Dells normally have to use the smbios interface to get at such things but if sending the monitor DPMS standby doesn't turn off the backlight this sounds like a quirk of the graphics card...
