For a few days I struggle to calibrate my dual monitor setup (Dell XPS15 laptop and Dell S2240M monitor). I used Eye-One to calibrate them and I'm pretty happy with laptop monitor profile, but the external one looks too cold and greenish. However I LOVE how Photoshop changes the colors when I drag a photo on the external monitor (at first its greenish, but then it adjusts and looks great). I don't quite understand how this all color profiles thing works and how Photoshop uses profile of the primary monitor (that's what I remember from reading somewhere). So I wonder if there is any possibility to adjust the external monitor like Photoshop does?
Anyone? How do I edit the profile then?
You are talking about ICC Profiles and that can be done for each display in Windows 7 ICC Profile Settings. The explanation from Microsft is here:
