<x-charset iso-8859-1>Thanks for all that helped me to decide. After the last update to my monitor nightmare, I removed again the corner purity compensation and saw a beautiful even screen. So the "visible" corner discoloration doesn't "install to stay X time after connecting the monitor" -- it seems to be an imprevisible and not permanent disturb. I addressed a suspicious look to a phone that came back recently to the room, remembering that it had been put in another room because it interferes with my sound recordings. After reading Wire Moore post about magnetic interferences, the phone seems even more culprit. I will follow the suspect and see what happens, but, at least for now, situation is under control: I won't, for now, replace a problem-free or, at the utmost, a slightly defective but well tolerated monitor with an almost certain monitors infernal dance.
