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 models of the computer might support NVIDIA Optimus Graphics.
To achieve the best balance between the computer performance and a long battery life, depending on the
graphics quality demand of the running program and power plan settings that you use, the NVIDIA Optimus
Graphics feature automatically switches between High Performance Graphics and Energy Saving Graphics,
with no need to restart your computer, close programs, or intervene manually.
