New 27" iMac screen isn't as bright as my 2009
Has anyone else noticed their imac's not being as bright? I've turned off the adjust brightness automatically in the system preferences. I have my 2009 and new 2013 side by side and the 2009 can go 2 clicks brighter than the new 2013 imac. By chance is it something where the new machine's lcd needs to be used for a few days to warm up or is there something possible wrong?
iMac (27-inch, Late 2012), OS X Mountain Lion (10.8.2)
