Using Apple Cinema Display Through Bootcamp and Windows 7

I recently purchased a 27” Apple Cinema Display to use with my 2009 MacBook Pro. Due to using QuickBooks Pro I have to use Windows 7 from to time through Bootcamp. The contrast with the Apple Cinema Display when booted in Windows 7 is very dark. Does anyone out there have have experience setting Apple’s 27” Cinema in Windows 7? I have gone into and switched a few of the Display Properties and the G Force video while in Windows 7 but nothing seem to work in brightening up the display.
