I've been scouring the web over these past few days for some calibration settings for you to try out, but I have been unsuccessful so far. Keep in mind that each LCD screen will have a different optimal calibration setting because no two panels come out of a manufacturing plant exactly the same, so any calibration settings you may find will only be useful as a starting point for your own TV's calibration. You can calibrate the TV yourself quite easily with a calibration DVD. Check out this link: TV Calibration Review 2013 | LCD Calibration | HDTV Calibration Disc - TopTenREVIEWS
LG WRman Sherlock, out!
you can use free calibration disc which is released by AVS forum I don't remember its name.
