Sony WE5 picture settings?

have this week purchased a sony kdl46we5 along with the 360 player. The tv I purchased after reading the review that was posted on site. What I would really like to know is what settings you guys used for watching sky HD & the blu ray. Have had for a few days now & I can't seem to get as good a picture as I was getting with my kdl40w3000. Please help one frustrated viewer.
