This question already has an answer here:
I have a 2012 Macbook Pro and a Dell U2417H monitor. Using the software that came with Spyder Pro 4 the monitors ended up looking radically different in color temperature. The Macbook Pro display was much, much cooler than the Dell.
I calibrated again, but this time using the Dispcal+Argyll tools (using the Spyder 4 input device). The two displays are much closer, but still different (the Dell is still warmer).
Note that I'm not a color profile pro. I just accepted the defaults when using both toolsets.
Am I expecting too much? Should I expect them to look the same?
