I am considering a Hitachi 60 inch rear projection LCD as the Samsung DLP produces eye fatigue. I noticed that the Hitachi's black levels seem much better than the Sony or Panasonic LCDs. In fact, they seem to be close to the Samsung black levels. Unfortunately, I have only seen the Hitachi at places like CC and Sears (Bright Environment). I am looking for input from owners that have tweaked this set. How do the Hitachi black levels look in a dark room?
