Still not sure what the "luminance" setting does, so left it alone.
Knd, plugged in your settings, and my set measured WAY off, the DE's for greyscale were all over 30, and primary/secondaries were way off (yellow and green were the only DE's under 40!), luminance was a mess and gamma was a disaster under 60%.
Spent 30 minutes recalibrating, and the results were visually much better and measured better as well. Though the temperature ended up too red (below 6500) under 60%, and I spent some time trying to fix it but kept ending up the same. Will have to learn how the various % adjustments impact each other with the 10pt system the LG uses.
Colors ended up decent, but the 2D CMS system wasn't overly useful. Could get the luminance of the colors almost bangon, but that's about it. Fooling with the "tint" adjustment for each color tended to make the colors worse for the most part. But they ranged from a DE of 2.4 to 6.5, and really anything below "10" is pretty good, while anything below a DE of 3 is supposedly almost impossible to detect with the human eye.
So either our sets are way off in terms of QC, or our measuring tools are!!
For anyone without measuring tools, I'd recco leaving the white balance and CMS adjustments alone. Stick to Expert 1 and use a setup DVD to set contrast, brightness, then color and tint (keep the color temp at warm and all the fancy stuff "off", unless you prefer Dynamic contrast and other gimicky stuff). You'll probably be better off that way.
I may keep this set though, as it looks quite nice for a $599 LCD. Black levels are decent, IF you sit directly in front of the TV, colors are pretty natural (green is a bit over saturated but not horrible), and I don't notice any motion issues.
Cons are typical of LCD's. Anything remotely off-axis and the PQ takes a dramatic turn for the worse. I.e., blacks turn a brutal shade of blue, hazey screen, etc. My main set is a 60" Samsung plasma from a couple years ago, and it's astonishing how incredible the PQ is from any angle in comparison!
Have 90 days to return it, so I'll keep playing around with it and once I get grey scale to a point where I'm happy, will post the settings (even though they may be useless).
I may try to price match (if a site that has a cheaper price actually gets them in stock) in which case I'll end up returning this one and calibrate a new one to see how close the settings hold.
