That is normal, unfortunately. Even with identical software settings, different monitors can have slightly different hues, sometimes more noticable, sometimes less. It comes down to physics: Different circuits, different construction, different materials.
For two monitors to appear identical, even to a trained eye, they need to be physically identical in every way possible, and fed the identical signal from identical graphics hardware. Even then, consumer monitors are not built to that level of precision. You would need to have (expensive) professional monitors to achieve that degree of sameness.
With consumer hardware and software, you'll have to fidget with settings and you can come pretty close, but not identical.
