I have a 27' Apple Led Cinema Display. The problem is i cannot adjust the brightness. F1 and F2 keys on the keyboard are unable to adjust the brightness. And on the System preferences > Displays > the brightness pane is not there. Am using OSX 10.6.8 Mac Pro. The monitor cables are connected properly. Anyone with a solution? Thanks. J Mwaura

Mac Pro, Mac OS X (10.6.8)
