You should pay attention to the following points when setting contrast level.

1) Go for the maximum contrast that is comfortable for your daily viewing. I assume that your plasma has been sufficiently run-in to avoid the potential risk of screen burn.

2) Avoid hard clipping of peak whites at the higher end of DVE grayscale steps. Not all TV will clip though.

3) Make sure the colour of peak whites do not change or shift when increasing contrast level.

4) You want to be able to see highlight details and make sure that your contrast setting is not probelmatic in say, bright afternoon scenes.

Take care and good luck.
