Photoshop colors off... grayscale looks brown.?

I got a new monitor and all the colors look fine except in photoshop. Now I know I had to change the color settings over to my monitor and make sure each file I open was on my monitor setting and yea it improved the colors a lot allowing the white to at least look somewhat white but when I grayscale a picture it looks brown not gray yet when I save it, it saves as gray which is fine but is hard to judge what it will really look like completed when I'm in photoshop.

Can anyone out there help me?

I had the same problem, only my grays turned into purple. I fixed it disabling Color Management and setting my monitor as Plug and Play but I don't know if this can work for you too.

good luck :)
