    If I remember correctly, the reason for the differences in your display is because both the Intel and ATi graphics adapters use different color settings through their software... as an example when you switch to your ATi card your Intel adapter's software also terminates, and the ATi software takes over.

    It might take some tweaking with both your Intel and ATi software, but you should be able to get the color casts and etc. to look identical if this is a bother for you.

    is this actually visible when you are sitting in front of the laptop normally or is it just the camera automatically adjusting settings.

    Did you recently upgrade to BIOS v3.19? The same thing happened to me. I went back to 3.18 immediately and that problem went away.
