“CalMAN for BRAVIA” interacts with and allows CalMAN® (Portrait Display’s display calibration software) to directly adjust this TV's picture quality settings (e.g. brightness, white balance, etc.) through its Direct Display Control (DDC) and AutoCal™ features. To run AutoCal, please download, install, and launch this app on your BRAVIA TV.
Currently, this app only supports the MASTER Series models:
This app by itself does not perform calibration. For more details, check here: https://calman.spectracal.com/sony-autocal.html
While this app is running, your BRAVIA TV waits for communication from CalMAN. In theory, this means other devices running on your same network might incorrectly adjust picture quality settings for this TV. Terminate "CalMAN for BRAVIA" once calibration is complete to reduce this risk (the app will terminate automatically if it's idle for too long).
