Dual screen and resolution problem on one screen.

[LarsW_Tierp]

Hi.
Sorry to bother with a question about this, but I'm stuck.
I have a Nvidia GeForce 8400 GS VGA out and DVI.
2 Screens with the same resolution (1280*1024). Not the same brand, but same resolution.
Both screens works fine when connected to the VGA port.
I use Nvidia driver 190.42

The screen connected to the DVI port via DVI/VGA adapter does not allow any resolution above 1024*768.

This is my Xorg.conf. It does not matter if I change the resolution in this, the only known effect it had was that one screen did not work.
