Hello,
Can anyone help me? I have been having a problem with my work Mac for a few months now and cant figure it out. I have been searching for hours and have not seen another situation like it.
Hardware Background
Mac Pro
Two 2.2GHz Quad-Core Intel Xeon processors
3TB hard drive
RAID Controller Card
18x double-layer SuperDrive
ATI Radeon HD 4870 with 512MB
Apple Mouse Keyboard
Samsung 24in Monitor
The Problem
When I am using any software, the screen will dim like its in Expose or Dashboard without icons. Just dim But the computer functions normally, just hard to see. Its very frustrating and distracting. It also happens when moving folder windows around on the desktop and scrolling thru Adobe Bridge or in cover flow view. Almost like there is a hot spot for expose setup in random parts of the screen. But the windows don't move just dims on different levels of darkness depending on the hot spot or pixel.
I have tried different settings for Expose energy saving, Universal Access. I have tried setting up multiple accounts and dumping user preferences. I have tried reinstalling software and resetting PRAM and repairing permissions. I am running out of ideas
if anyone can help I would greatly appreciate it.
-Thanks
