iMac gamma trouble
I have an iMac 24", running OSX 10.5.8. I saw occasionally when I wake my Mac from screensaver, the gamma is off. The screen comes to be really white-washed looking. I can get it back to regular gamma by shooting up System Preferences -> Display without transforming any kind of setups.
I do this every single time and also it's come to be really aggravating. Can a person inform me what's taking place and also just how I can repair it completely? I do not have this trouble on my MBP.
