Win 7 Brightness doesn't work after graphics update
Hey,
I have a late-2010 MacBook Pro running Bootcamp 4.0 with Windows 7 64-bit. My graphics card is the nVidia GeForce 320m. I looked online recently and found that there was an update available for my graphics card (previously I had the one that comes with bootcamp, which is from 2009 I believe--quite outdated you see). So I installed it, hoping for better DX11 support, etc... It installed fine, but now my display is stuck on 100% brightness, when before I could adjust it with the F1 and F2 keys. When I try using the keys it shows the Apple popup with the slider moving, but the brightness doesn't change. I went into Control Panel > Power Settings and tried adjusting it from there, with no luck. The nVidia Control Panel doesn't have any satisfactory controls to do this either. It must be, of course, that the driver update changed things, but I'm not sure how to rectify the situation. I uninstalled the Apple Driver-Display from Control Panel and then re-installed from the Bootcamp files, but it didn't help. I've heard some talk about Apple Cinema Display, but I'm not sure if that's the same thing as the Display and whether I should be looking for a driver for it.
Any help would be greatly appreciated!
MacBook Pro, Windows 7
