My workaround consists of these hoops to jump thru, but once you have different display profiles setup to switch between, and I find it pretty usable now.
FYI -- I only have problems on my built in LCD screen on a summer 09 macbookpro (model 00009CB1). Not the Dell LCD as my primary monitor.
Adjusted the CONTRAST settings about 1 unit to the right (system preferences-Universal Access).
Adjusted a new LCD Calibration and selected a different white point. Used SIMPLE settings for the calibration.
Selected:
Gamma 2.2
D50 White Point or NATIVE (this is the big difference for me)
Save this as a new setting!
When you are selecting WHITE POINT, you will notice that it looks different as you choose different radio buttons, and the order in which you switch seems to matter.
There appears to be a problem in the way the System switches between them. So if I go Native to 9300 (tv) then I get a lot of the blue. Anyway, keep toggling until you get the screen to look like you really want it. I am finding the D50 white the most stable.
*Now when I need to reset the monitor, I can just open the DISPLAY PREFS and toggle between 2 different Display Profiles that gets the white balance to reset when going back and forth.*
Anyway, it is holding me over till Apple sends us a REAL fix!
