I used the one that came free with Adobe Photoshop - if you've got that and haven't seen the utility, it should be somewhere in your control panel. But I don't use Photoshop on my new PC and I set that up using WiziWYG from Praxisoft - the monitors and video cards on my three machines here at home are completely different but WiziWYG and the Adobe utility have meant that my images look much the same on each system (not identical though). As for colour matching when printing - that's a whole different ballgame mainly due to the reduced colour gamut when printing (especially for blue).
