Multiple monitor calibration and matching? - Adobe Color Management

You should be able to do it. It depends how bad the monitors are and what onscreen controls they have but generally you'll be able to get them pretty close.

The key is to set and achieve the same calibration targets for all monitors. If one of them isn't capable of achieving the set targets you will have to adjust those targets for the rest of them.

The targets include (in the order of importance):

white point (I suggest D65 or close to that)
white luminance (~100 cd/m2)
gamma (2.2, sRGB or perhaps L*)
black luminance (~0.25 cd/m2)

Generally I'd calibrate one of the monitors first and then load it's profile as a target for the other two. Then run validation and see if the targets were reached. Spyder2 Pro would work for this purpose. So would Coloreyes (which is a higher end and more expensive software). Eyeone Display2 can be used but is a bit limited in software functions for this particular task (like, it doesn't measure black point and gives limited validation information) .

Note: Spyder2 pro does not offer D65 as a target. So either set it via coordinates (D65 is 0.313, 0.329 CIExy) or just use 6500K which is very close to it.
