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.
Using the NVIDIA Optimus Graphics feature
Some ThinkPad notebook computers support NVIDIA Optimus Graphics.
The running program and power plan settings that you use on your computer have specific graphics quality
demand. To achieve the best balance between the computer performance and a long battery life, the NVIDIA
Optimus Graphics feature automatically switches between High Performance Graphics and Energy Saving
Graphics. You do not have to restart your computer, close programs, or intervene manually.
