How to remove the yellowness of the screen?

Question

Monitors

I bought a new monitor, connected it, everything works fine. I connect my old monitor as a second one, and it turns very yellow. This was not the case before.

Both monitors from Samsung:
Old: Samsung 20" SyncMaster2032MW (the one that turns yellow very strongly)
New: Samsung 23.8" S24R358FHI

The integrated solution from AMD acts as a video card: Radeon HD 6530D I

checked the settings of the monitor itself - everything is ok. I even tried resetting it to no avail. Whatever brightness / contrast / color gamut settings I set, it still goes very much into reality and I didn’t manage to get even a millimeter closer to the white color.

I tried to make settings in AMD Catalyst, but also to no avail.

I thought that the problem was that I connected the old monitor via a VGA to DVI-D adapter, but no. Changed places, but all to no avail.

I already thought that the problem is that there are two monitors. I removed the new one, leaving one old one, but it still turns yellow. I tried to connect directly via VGA (as it was before) and through an adapter - the result is the same. I don't know what to do anymore, Google didn't give me anything.
