Regarding the built n LG color filters. You may want to do some real movie viewing or even check it with another media disc or two. I've found that using the filter on my TV produced some inconsistent results. Very bright reds and blues seemed over saturated, even though when AVS HD 709 was viewed and adjusted they weren't. When I compared to AVIA and some THX color media, there were differences.
Brightness is always the easiest to dial in. I ended up at 51, because that is when 16 disappears for me. Contrast is a little trickier on our LCD TVs, because the brightening effect is deceiving. The disc tells you it needs to be set much higher (at least 90) than it really should be (83, in my case). This is to be expected with LCDs, though, because they're so bright.
Using the built-in filters for red, green and blue was interesting. As expected, blue was super easy to dial in, adjusting only blue, cyan and magenta in CMS. Green and red were much harder, because it's impossible to match them perfectly with gray. I would have had to max out red at +30 and dial down green to -30 to get close.
I ended up having a perfect match for blue (+7), with a slight increase in red (+8) and a decrease in green (-12). That way my blue matched gray, cyan and magenta, my green matched cyan and yellow (but not gray), and my red matched magenta only. Nothing was oversaturated either.
Since I did not touch luminance at all (2 or 10 point), I'm sure my grayscale is not very accurate. It did look balanced, though, with no red or blue tint, as far as I could tell.
Here are the things I left untouched (at ISF Expert defaults):
Sharpness, Color, Tint, all luminance settings, all CMS tint settings.
Backlight is now at 20 for nighttime and 40 for daytime with lots of light.
I'm assuming that there is no way to match all three primary colors perfectly with gray as well as all three secondary colors. It seems that you always have to find a compromise, and the AVS HD manual suggests to calibrate for blue first and foremost. I think this is the best I can do without meters
