Thanks, calibrating step by step through "View Button" I don't see tend to the right behaviour anymore, my fault was that I didn't do the full calibrating process previously at Test-Mode, just partially. Thanks a lot for your response.
Just one last doubt, is there a recommended graphical setting for best graphics as 4:3,FXAA, post-processing, 4x or similar, currently I'm playing with 4:3, 4x but perhaps there's a way for best graphical experience. Thanks!
