There are several reasons why a calibration reminder might appear.

You can choose the number of days up to 14 for the calibration to remain valid.

When the calibration has expired, a reminder will appear, indicating that you need to calibrate to ensure that the monitor's color and luminance are continuing to meet the specifications in the reference profile for the monitor to achieve excellent color match.

1. Perform one of the following actions:

• Click Open App to open the MV Calibrator and use CALIBRATE to confirm that the monitor is still accurate. 
• Click Cancel to ignore and the reminder will appear again in an hour.
