VNC Server resolution change after loggin


My desktop have two monitors 1920x1080 and 1680x1050. I change the geometry value in /etc/xinetd.d/vnc from the default 1024x768 to the 3200x1080, so i can have access to whole desktop.
In the login screen the resolution looks correct but as soon as i type the user name and password it reverts to default 1024x768.
I have spend several hours looking at the forum and the web for an answer.
Sorry if i miss it.

The server running in an Opensuse 13.2 with KDE desktop
The client is UltrVNC in a windows7 Laptop

Thank you in advance

Have you tried changing the display resolution using your Desktop tools?

If you don’t know how to do this, post whatever Desktop you’re running.
