Hi bh12,
I have the 50pc3d and here are my settings after calibrating the tv with the Digital Video Expressions calibration dvd.
Contrast: 45
Brightness: 37
Color: 49
Sharpness: 50
Tint: 0
Temp: Cool
These settings may not be perfect for your eyes or viewing area but it is a start.
I like this dvd, though I have not used any of the other offerings out there, but it is a bit of a chore to navigate through and the calibration tutorial is like taking a class. You have to listen to a somewhat lenghty history of each calibration setting before you actually use it but it is a good tutorial for a first time user and worth the time.
Prepare to spend an hour, more or less, but once you get through it you can then go straight to the calibration screens.
I also used it to check/validate my audio settings after using my receiver's YPAO system and my spl meter.
Good luck and let us know how you make out.
