Colour on screen issues....

Ok, im confused....

 

I have my colour management set to professional output..and everything was working great...then the other day...all the colours changed..now all the colours look like extreme rgb variants....ie blue=very bright blue..same as red, etc etc.

 

no matter what i change the cdolour manafgement settings too, it stays the same....

i even resaet my workspace, still no change....and its on both of my monitors....what happened...its very annoying designing for cmyk when everything looks like extreme rgb:)

 

Thanks
