The following are screenshots of the settings we used to calibrate the Sony X850D UHD LED TV. These settings are good to use with any kind of content from movies to sports to video games. If you want to use them for the later, make sure to copy the settings under the 'Game' picture mode.
As with all Sony TV, we begin by selecting the 'Custom' picture mode. In our test room, we had to set 'Brightness' to minimum to get close to 100 nit. If you have a bright room increase 'Brightness' to maximum.
A color temperature set to 'Expert 1' will give a warm picture look. If you find the overall picture too dull, feel free to use any other colder setting. For almost all content, leave 'Color space' to 'sRGB/BT.709'. To get more saturated color, use either 'DCI' or 'BT.2020', the wide color gamut option.
'Sharpness' to 50 equals to no added sharpness. This will look sharp without any artifacts resulting from over-sharpness. For streaming, cable TV and DVDs, 'Random noise reduction' and 'Digital noise reduction' will help to reduce unwanted picture noise. Leave those options off with high quality signals (PC or blu-ray).
To add image interpolation (soap opera effect) and smooth out motion, engage the 'Motionflow' option to one of the preset values, like 'Smooth' or some custom values. The 'True Cinema' setting will remove judder on 24Hz content. For 60Hz content, also set 'CineMotion' to 'Medium' to eliminate judder. The 'Clearness' setting will make the backlight flashing while reducing the overall brightness of the TV. This can be useful to clear motion while playing video games without increasing the input lag.
To get sharp text while using the TV as a PC monitor, change the 'HDMI signal format' to 'Enhanced format' and use the 'Game' or 'Graphics' picture mode. To get there, hit the 'Home' button on the remote, scroll down to 'Settings' then 'External inputs' and 'HDMI signal format'
The following are the results of the white balance and colorspace calibration on our unit. You can try copying our values for these, but we don't recommend them as they vary per individual unit, so they might not be good, even for the same model and same size as the TV we reviewed. If you want to try them you will need to enter all values shown, as all of them are active at the same time. If you end up with worse picture quality, simply reset them to the default values.
