you will always get differences in tone / contrast between manufacturers / models - but it will give you a better result.

Check that your vid card can deal with multiple profiles, and also make sure your editing programmes are also working with those profiles.  It is a massive headache to set it all up - my lightroom and photoshop still give me overly warm renderings of photos despite the screen output being neutral...

My main advice would be to do it over a weekend, this isnt something to do one evening after work...

Man is the dream of the Dolphin"
