Using The Nvidia Optimus Graphics Feature; Using Audio Features - ThinkPad P50 User Manual

After you use the color sensor for the first time, a calibration profile ECCM2SensorData.dat is generated. Back
up this calibration profile on an external storage device in case that both the color sensor and the internal
storage device are replaced.
To locate the DAT file, do the following:
• For Windows 7: Go to C:\ProgramData\X-Rite\ECCM-2.
• For Windows 10: Click This PC ➙ Documents ➙ X-Rite.
If your computer comes with a color sensor, the display provides a color profile that can work with the
Microsoft Image Color Management (ICM) function. If the graphics software you are using is compatible with
ICM, you can display a color image on your monitor and match it with the same quality one on another
device, such as a scanner or a printer.
For more information about the Microsoft ICM, refer to the Windows help information system.
