This issue can be caused by the different spectral outputs of the two displays causing the human eye to see color differences differently than the color sensor used to calibrate the displays. In this case the numerical measurements from the color sensor are identical on both displays, but they do not visually match. Manually visually matching one display to another can usually avoid this issue. The basic steps to take are as follows:
- Calibrate both displays.
- Pick one of the displays to be a reference. Call this display #1.
- Select display #2 in SpectraView and open the Custom White Point dialog. Use the Visual Match tool to adjust the white color so it visually matches white shown on display #1.
- When a visual match is achieved, put the sensor over the measurement area and click Measure. This will enter the value that the sensor perceives into the White Point. Save this as a new Target.
- Recalibrate display #2 with this new Target. From now on always use the respective Target to calibrate each display.
