Spent about half an hour yesterday changing the order of the screen stack on my Sony KP44 PS2. Wow what a difference it has made. I would class it as a must do (also SVM disable is in this catergory). Screen now has zero reflection, and the picture after resetting setting for contrast / brightness / sharpness is out of this world. Top marks to Sony for producing such a good set and top marks to all of us tweakers for making it 50% better than when it left the factory.
