So I'll defer to the thousands of prior discussions.
http://reviews.cnet.com/flat-panel-tvs/lg-55ga7900/4505-6482_7-35560995.html seems to have a fair user review but are you seeing folk that like the crushed blacks? I do so it must be user preference and it's good they let us tinker.

Just got this tv. I really like it. Working on calibration and was wondering what anyone's opinion is on the "Dynamic Contrast Ratio". Seems to crush blacks so I have it off now.
