Anyone else having problems with the screen changing
brightness on its own. It fixed its self when I opened
system prefrences and then display. NOTE: I adjusted nothing when I opened the displays preference. I will
also mention I have my brightness controls locked on the side of the display.
I am running the new mac pro tower. My old 23'' inch used to do the same but turning the screen on and off fixed it. I figured it was just getting old. I was running the G4 then.
I did have the display calibrated.?!
Thanks in advance if anyone can help.
