Color problem

Hi all,

I have HP laptop and a Dell screen attached to it. I have used Spyder 3 to callibrate the colors (measuring on the Dell screen as this is my main view). I have created profiles for both the single screen and the dual screen setup, but I notice that (mainly) the saturation goes down when I go for the dual screen setup. Switching profiles (to test) didn't make a difference. I tried to set the profiles in Capture One itself, but that didn't make a difference either. And depending on where I am in the switching between the two setups, I notice that the colors in the browser and the viewer of Capture One are different, even when on the same screen.

Does someone have any ideas on what I could do the keep the same colors viewed on my Dell, whether I'm in the single or dual screen setup?

Thanks!

Kind regards,
Andy
