I just purchased the Samsung 46' LCD C610 and it is awesome so far. I have my PS3 hooked up to it via HDMI but I noticed something. The specs say it is a 120hz TV but when starting a blu-ray the top left corner says "1920x1080 60Hz". Is there a setting I need to change or is this more related to the source material being played? Any info would be much appreciated. Also I read something about calibration settings that you should use for your TV, not sure what that's about seems pretty good to me.
