I routinely suggest +6 because it seems to me to be the sweet spot; a drastic improvement without looking over-processed. That's a matter of personal taste, however, and if maxing out the setting is working for you, by all means stick with it.It was mentioned in a different post that you should set you "sharpness" level in the "Set Picture Control" to 6 . Why wouldn't you want the best sharp picture and set it to the maximum 9 ? That's what I did for all of them. Is that wrong ?
