Corrections to settings.
I own an LG 42LK450 and attempted to calibrate per these settings. A couple comments.
(1) There is no "LED Local Dimming" option, this TV (at least my version, 42LK450-UB.CUSYLH) is an S-IPS LCD unit and is not LED-backlit.
(2) The "Real Cinema" is grey'd out and does not present itself as an option for an HDMI input with my blueray-equipped PC plugged into it.
(3) These settings, although producing deep blacks, also produce an incredibly dark picture, even in a dark room at night. They need to be much brighter.
