Regardless I'd head over to the ES6100 thread if you're looking for calibration settings as well.
My father just recently bought a 55 inch, and I'm trying to help him set it up. The biggest problem we have is that it keeps cutting off the top and the bottom of the pictures. We keep changing it around, but nothing seems to help. We're using an HDMI cable that a friend gave us, from an Infinity cable box. Oddly enough, when we switch on the Roku, the problem seems to go away.
So any ideas on a possible solution?
