For anyone stumbling across this problem, the reason for the behaviour of the DynamicTwinView is described on http://us.download.nvidia.com/XFree86/Linux-x86/1.0-9755/README/appendix-d.html :

"Option "DynamicTwinView" "boolean"

Enable or disable support for dynamically configuring TwinView on this X screen. When DynamicTwinView is enabled (the default), the refresh rate of a mode (reported through XF86VidMode or XRandR) does not correctly report the refresh rate, but instead is a unique number such that each MetaMode has a different value. This is to guarantee that MetaModes can be uniquely identified by XRandR.

When DynamicTwinView is disabled, the refresh rate reported through XRandR will be accurate, but NV-CONTROL clients such as nvidia-settings will not be able to dynamically manipulate the X screen's MetaModes. TwinView can still be configured from the X config file when DynamicTwinView is disabled.

Default: DynamicTwinView is enabled."
