The brightness control on my brand new iMac 27" appears to be "stuck" at half-way.  The display is not very bright and I'd like to increase it, but when I press the F2 brightness key, it will go down, but not up past half-way.  Is this a retina display thing or indicative of some problem.  It does appear dark and I'd like to brighten it up some. 

iMac (27-inch, Late 2012), OS X Mountain Lion (10.8.2)
