For some reason I cannot reply to this post: http://en.community.dell.com/support-forums/peripherals/f/3529/t/19470288.aspx
So i write a new one instead.
I can confirm this issue with revision A00. The color is much warmer than in earlier revisions. The white looks more "dirty" or yellowish. Since so many have reported this I wonder if this is the way it should be.
Can Dell please tell us the differences between different revisions for Ultrasharp U2412M monitor?
