I just got a 42px600u a few days back, and I have a couple questions. First, what aspect setting do you prefer when watching standard broadcasting. I'm having a hard time getting used to the "squished" people look and I don't like the borders of 4:3. Second, suppose I have the TV set to "Just", if I go to an HD program, will it correct itself to the proper ratio for HD or do I have to change the settings. Third, what does C.A.T.S., color mng., 3d y/c filter, and color matrix do? Oh, yeah, I'm still looking for that "perfect" video setting so if anyone has one they really like, I'd love to hear it.
