ATI CCC and new LCD problems.CCC wont fully uninstal

I got a new acer (G245H)24"LCD display the other day.My first LCD.
I thought it was too bright so I used the monitor controls to turn down the brightness from 70 to 35.Better but not perfect...Yet. I then noticed a Digital panel (DVI) control in CCC and it had a Brightness and contrast sliders under adjustments so I turned down the brightness to -7 and I got a perfect black level.Wonderfull.
But then I went to the color option under 3d and clicked the reactivate ATI color control and that just messed it up and now it looks washed out again.And there is no way to deactivate the color control that I can find.
I tried uninstalling all the ATI drivers and software even removing all ATI folders in c drive and program folders and clearing out the temp folder.NO luck...System restore...No luck.
And Ati is leaving something on my system because the three times I tried to start over CCC came up with the exact settings it had before I uninstalled it.And I removed all the ATI drivers,CCC and folders.It must put something in the registry and that is BS because there uninstal utility DOES NOT uninstall everything.And I even tries using REVO uninstaller.
I want my perfect black level back.It seems my only option is to reformat my main drive and do a fresh XP install.What a pain.

Unless any of you know how to deactivate that ATI color control.And does 10.3 have the same DVI adjustments.I tried 10.2 but no brightness/contrast sliders.Only color corection....????????
