kevdmb,
Typically, STANDARD or NATURAL presets are a good spot to start for self-calibrations in daylight, and MOVIE for night. There is a HDTV Picture Settings forum on C|Net for just this purpose, however, and that can be found here.

Are there any recommended settings for day and night calibration settings here?
