LCD color management (photoshop and acrobat)

[clicknext]

I just found that after installing my LCD, when I use photoshop, all the colors look screwed up. Most things turn magenta and green. This can be cured if I set the working space in the options to my monitor color profile, but that only works for RGB color. The monitor profile can't be selected for CMYK color. It looks the same way when I look at stuff in the acrobat reader. I have the Viewsonic VG151 monitor.

How can I fix this? Thanks.
