I couldn't find anything online, either, but I did run the THX Optimizer on it, and tweaked that amongst various types of programming. I found the best results to be:
Contrast - 45
Brightness - 52
Color - 75
Sharpness - 50
Color temp. - Normal
Backlight - 70-75
This provides for rich blacks without sacrificing detail in the shadow or highlight areas, vivid color without bleeding, and bright whites without blowing out the skin tones or losing detail in the whites. It's pretty spot-on, though not by any means a professional calibration. Just 95% of the way there.
This seems like a really new hdtv and I can't find anything anywhere online for it. Any help would be appreciated.
