These are the settings we used to calibrate our Sony 65" X850F TV, and we expect them to apply to the 75" version (XBR-75X850F) as well. The 85" version likely does not use the same panel type so the settings may vary. The following settings are good for most content, from watching sports movies and tv shows to gaming. For gaming, some minor adjustments need to be done, and they are listed below.
For movies and TV content, the 'Custom' picture mode provided the most accurate colors and brought us closest to our calibration goals. This is necessary to bring the image quality closest to what the content creator intended it to be. 'Auto picture mode' was left to 'Off', since we do not want the TV to adjust the picture settings depending on content. We turned the 'Light Sensor' to off since lighting is fairly constant throughout the day in our lab. If the ambient light in your room changes throughout the day you may want to leave this setting on.
In the 'Brightness' tab, we set 'Brightness' to minimum, since this is closest to the 100 nits we calibrate to for a dark room. You can adjust this depending on your room brightness, it will not affect picture quality. We left the 'Contrast' to 90 as it gave us the best results without clipping the white levels. 'Gamma' was also left at 0, but if you notice any black crush while watching a movie you can raise it to bring in more detail. The 'Black level' was left at 50 as we found it to be the most accurate. We rarely find any benefit to adjusting the 'Black level' with normal content (a low value will often only crush the shadows). The 'Black adjust' and 'Adv. contrast enhancer' were left turned Off since these are only image processing and don't affect the actual contrast or picture quality of the TV.
In the 'Color' tab, we left 'Color' set at 50 and 'Hue' at 0, since the default settings are the most accurate. We selected the Expert 1 'Color temperature' as it produced the most accurate colors and was closest to our target of 6500K. If you find the picture quality to be too cold, you can set the color temperature to something you are more comfortable with. 'Live Color' was also left turned Off, once again since this is the most accurate setting. When turned on, 'Live color' will oversaturate the color, making on-screen content more vibrant, but the resulting picture quality will be less accurate. The 'Adv. color temperature' is where you can adjust the 2 point and 10 points white balance. You should only adjust this if you have advanced calibration tools.
In the 'Clarity' tab, we left 'Sharpness' at the default value of 50, since we don't want to add sharpness (high quality, high-resolution content usually doesn't need extra sharpness). 'Reality Creation' was also left turned Off, but turning it on can help improve the picture quality of some older, low resolution content. When turned on you can adjust the 'Resolution' slider to choose how much effect you want to add. The 'Mastered in 4k' option is a feature that will optimize the upscaling of 1080p Blu-ray movies that are listed as having been 'Mastered in 4k'. This option is only available with some input settings. 'Random noise reduction', 'Digital noise reduction', and 'Smooth gradation' were all turned off, but these could all be useful when watching low-resolution content.'Smooth gradation' could be especially useful if you see any color banding with 8-bit content.
In the 'Motion' tab, we left 'Motionflow' and 'Cinemotion' off. If you like the effect of motion interpolation (commonly known as the soap opera effect), simply set 'Motionflow' to Custom, and increase the Smoothness slider. The 'Clearness' slider controls the image flicker of the TV. To find out more about motion interpolation, click here.
If you are watching lower frame rate content(for example cable), and notice some judder, simply set 'Motionflow' to 'True Cinema', and 'True Cinema' to High to remove any judder, without adding the soap opera effect.
In the 'Video options' tab, 'HDR mode', 'HDMI video range' and 'Color space' should all be left at Auto. The TV will almost always select the best setting automatically depending on the content being played.
For a dark room, we set the TV 'Brightness' to Min, which gave us a luminosity of about 100 cd/m2. This should be good for most dark rooms and home theatres. If the TV is still too bright, you will have to go the 'Motion' tab, set 'Motionflow' to Custom, and set the 'Clearness' slider to a higher value to engage the black frame insertion feature, which will considerably lower the luminance of the TV.
For a room with average lighting, we set the TV 'Brightness' to 11, which gave us a luminosity of about 200 cd/m2. This should be good for most average rooms with some light during the day. If you find the TV too bright or dim, you can adjust it to accommodate the ambient light in your room.
For a bright room with a lot of sunlight, we set the TV 'Brightness' to Max, which gave us the maximum luminosity the TV could produce.
Before connecting any HDR devices via an HDMI input (be sure to use either HDMI ports 2 or 3), you need to set the 'HDMI signal format' to 'Enhanced format' from the 'External inputs' menu. This will allow the HDMI port to accept the full bandwidth of HDMI 2.0. Note that only HDMI ports 2 & 3 support full bandwidth HDMI.
When HDR content is detected the TV should switch automatically to the correct settings. You don't need to change the picture settings to view HDR content, as the TV will simply change to HDR mode automatically. To check if you are in HDR, simply go into the 'Picture adjustments' menu, and you will see an HDR logo in the top right corner.
For playing games via a video game console or PC, you can choose either 'Game' or 'Graphics' picture modes to get the best input lag possible. Keep all other settings the same as above.
For HDR gaming, the same recommended settings from the HDR picture section are recommended ('HDMI signal format' to 'Enhanced format' and 'Brightness' set to 'Max'). Make sure to select the 'Game' or 'Graphics' picture mode, similar to what is recommended for SDR gaming. Again, the HDR logo will appear in the 'Picture adjustments' section when you are connected to an HDR source.
The following are the results of the white balance and colorspace calibration on our unit. They are provided for reference, and should not be copied as the calibration values vary per individual unit even for the same model and same size as the TV we reviewed due to manufacturing tolerances. 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.
