Choosing the correct picture mode has the biggest impact on the Sony X830C's calibration settings. We opted for 'Custom' to have full control over the settings. 'Game' is also a good choice if you want lower input lag or chroma 4:4:4.
Turning on 'Light sensor' can be helpful if you watch TV in a bright room during the day and in a darker one at night. The TV will adjust the luminosity by itself. But if your environment is constant, turn it off and use the 'Brightness' setting to control the luminosity instead.
The default settings are good under 'Custom'.
A sharpness of 50 means no sharpness added on this TV. Lowering it will blur the picture a bit.
Most people will probably prefer 'Motionflow' off. If you want the soap opera effect, turn it on and increase 'Smoothness'. 'Clearness' works to clarify the picture, but it also darkens the screen.
These are the 2-pt white balance calibration settings.
