Brightness Monitor

Hello everyone,
sorry I do not speak English.
I'm looking for a script to increase or decrease the brightness of the monitor. Can you help?

The first question I'd ask is, is this a laptop or desktop monitor, etc. Most laptop monitors have software/hotkeys for this, which would make things pretty direct/simplified for assigning a hotkey, etc. But if it was a desktop monitor, I'm sure it could be done via a few diff methods (have at least 2 ideas myself).

Cheers.

brightness no for desktop monitor
the control is on the monitor itself
and most likely u will hear ppl say overlay a grey/black gui, which has nothing to do with brightness

That was my idea!
Prob most viable, though I personally have absolutely no clue how to achieve that lol.

Goodluck with it, I searched around and this seems to be going in the right direction.

I've been curious about this as well for quite a while. It appears that Windows Vista or at least Windows 7 supports this programmatically, but I don't know how to take advantage of ACPI_NOTIFY_INC_BRIGHTNESS_HOTKEY and ACPI_NOTIFY_DEC_BRIGHTNESS_HOTKEY in AHK.

I needed a "real brightness control" script for use on xp laptops/desktops (not some dimming gui or gamma change). If anyone is interested I can post it. The Brightness, controlled by only two hotkeys (F5 for + and F6 for - which you can change of course) , using powerstrip soft running in the background.
