I have a problem with adjusting screen brightness on windows 7 x64.
If I change brightness with nvidia control manager, it works correctly but if I change it with windows, it is reversed. Pushing Fn+F6 button increases brightness instead of decreasing. The same it is with windows adjust brightness settings.
I use windows 7 x64, a graphic card geforce gt m230 and a display driver nvidia 314.07 on my laptop toshiba satellite a500-1c0.
Any help would be appreciated.
