The E32 is a series with many models. If I wanted the optimal pic I get it calibrated to the room by the usual folk. If I wanted to try some on the web calibration settings I find the forum for the model E32 in question on AVSFORUM and hope for the best.
Remember that the color of the room means that the optimal settings for a bright room won't be the same as a dark room. Same for yellow or green painted rooms. It's a myth there are optimal settings for TVs because of that.
