Below you'll find the settings we found best for viewing the LG 50PK750 in a dark room via the HDMI input with a 1080p, film-based source. Your settings may vary depending on source, room conditions, and personal preference. Check out the Picture settings and calibration FAQ for more information.

The above were used for our picture quality observations in the review. The below settings used the adjustments available under the Expert mode's 20-point system. Despite providing an excellent grayscale, the results of the adjustment below created an unacceptable picture quality tradeoff, namely excessive false contouring--which manifests as obvious, choppy divisions, as opposed to smooth, natural gradations, between colors and shadows--that was not present before our adjustments were made.
Even discounting the contouring, the LG's 20-point IRE system in this plasma didn't work as well as the company's 10-point system in LCD models we've tested previously. Its IRE numbers didn't correspond correctly to the true IRE windows; many adjustments affected more than one IRE window; and darker areas proved especially difficult. Nonetheless, after we accounted for those issues, the settings below gave us excellent results (nearly flat 2.19 gamma, a linear grayscale averaging 0.313/0.330 with only 41K variation from 6500K, etc), so we're including them here for the curious or experimenters who want a starting point. We still recommend strongly against using them, however, unless you're also curious to see what false contouring looks like.
