|Let me clarify all this...|
The all white screen will fix problems like "burn in" found on old crt monitors. Some lcd's will show a "ghost image" of icons, side bars, and wallpaper on the desktop. This was, aparently, a problem first found on some Mac displays.
Running a pure white screen overnight usually reduces or completely fixes this "burn in" or "image persistence". I've had to run to white screen for a longer period of time on some displays but it's always eventually worked.
