It's been a while and I've changed my hardware setup - which now makes it even more puzzling.
Now I have two "identical" Dell monitors - P2418D - and colors are different, one has whites cooler whereas the second's whites (thus other colors) are warmer.
I've been playing with 'colormgr' but am unable to make screens to look the same.
I've also done simple "factory reset" within monitors.
Perhaps that "warmth" is something else and 'colormgr' cannot fix it - would anybody know?
Or hardware calibration - event though it's the same monitor - is the only "fix" here?
Probably an obvious thing, but if you have 2 identical displays with wildly different colour balances, have you checked each display's "Color Preset Modes" in the OSD?
See page 38/39 of this PDF.
If this is set the same in each, then are you driving them over different standards? e.g. HDMI for one and DisplayPort for the other? Or one via a dock and one direct from the laptop? That /might/ account for differences?
