Comment 1 for bug 144546

I still can't use my max resolution (1920x1200) with the latest Displayconfig tool version 0.3.1.
The Resolution is only as virtual resolution available.

I could only choose 1680x1050 as Physical resolution.
I think it is related to the modelines.

Less information for the xorg file would be better, I think.
All I need is this two lines to get my monitor working at max resolution.

 HorizSync 31-80
 VertRefresh 56-76

The rest will do the driver I think.

Maybe the 60Hz is to much for my monitor.
Nvidia-settings shows me a value of 58 Hz (Attachment).
