LG 55LM6700 picture settings

Calibration report using these settings:

Below you'll find the settings I found best for viewing the LG 55LM6700 in a dim room via the HDMI input. Your settings may vary depending on source, room conditions, and personal preference. Check out the Picture settings and calibration FAQ for more information.

Calibration notes: Prior to calibration the most accurate setting was Cinema, but it was quite dark at less than 20 Fl, crushed details in shadows and looked very plus-red/minus-blue. I took advantage of the Expert settings for my calibration, boosting light output to my standard 40Fl. Among the three local dimming settings I settled on High because it improved black levels significantly compared to the others. The trade-off in gamma is worth it in my opinion.

LG's color management system is different from last year and while I was able to get it fairly close, it didn't seem as accurate as I remember (despite using the proper Luminance, Tint and Saturation commands--an LG first). The grayscale controls were flat-out poor, however, behaving much worse than on past LG's I've reviewed. Adjusting just the two-point system, the high and low settings interacted to such a degree that they basically just behaved like one control. The twenty-point system was broken as well; I had to crank the controls way up or way down to achieve a measurable change, some controls at some levels seemed simply ineffective and again there was too much interaction from one level to the next. I also saw significant variation from measurement to measurement and over time.

Given these issues I ended up not adjusting the 20-point system at all--a shame, since if it worked properly, as its predecessor did on the LW5600, I could likely have fixed the gamma issues of High local dimming--and only adjusting the High portion of the two-point system. Perhaps another calibrator with more time and/or skill could better my results, but after giving it my best shot I found the LM6700 controls disappointing, which hampered its color and gamma performance.
