imac 27 i5 display backlight adjustable levels (0-16) are perfect in OSX, "0" is dark enough for "dark environment".
However, running BootCamp 3.0 with Vista x64 : the backlight seems too bright at it's lowest adjustable level via the keyboard.

Anyone got the same problem?
Any advice to dim the LED backlight while in Vista x64? (level "0" at Vista is about equivalent to level "4" in OSX)

Thanks

?? - I'd probably try installing the latest drivers for your HD 4850 from ATI/AMD. That should give you all the brightness adjustment you need.
