These are the picture calibration settings that we used on our Sharp UB30U when testing it.
Movie picture mode has really good default settings. Just selecting this will get you 95% of the picture quality. If you find our settings too dark, increase 'Backlight' as much as you want. Do not touch 'Brightness'.
Turn off 'Motion Enhancement' if you do not want the soap opera effect. You might want to turn on 'Digital Noise Reduction' if you find the picture too grainy.
