I bought a new monitor, the LG IPS 224, and everything seemed fine til I opened the windows picture viewer: everything was green, it was like a green overlay . than I got another problem when I opened Safari: Then I had another problem in Photoshop: where the green rectangle is supposed to be white what it is when I save it and open it in picasa where I have no color problems.
The first error in the windows picture viewer I could already solve through changing the color profile to another one than the LG IPS224 profile, e.g. to sRGBIEC61966-2.1 which was recommended for problems with a samsung monitor. But it didn't solve the problem in safari and photoshop what would be most important. Even changing the color profile to Apple RGB and to Adobe RGB didn't solve the problem in Safari and Photoshop. The drivers are up to date for the monitor and I already tried to change settings on the monitor directly. On youtube is a video where the same problem is described, but no solution. and another strange thing is, on my second monitor I have the same problems, which I never had before.
