How did you get the smooth scrolling, mine is jerky? I have on board nvidia HDMI connected to a plasma. I have a 50 Hz setting in xorg.conf and the Xorg.0.log and nvidia-settings both report a 50hz rate, the TV however reports 60 Hz so may be down to a duff TV (Samsung).
No, it's a "useful feature" in the NVidia driver because NVidia's scaler does a better looking job than the one built into a typical LCD monitor. Add this to your "Device" section in xorg.conf:
Option "FlatPanelProperties" "Scaling = Native"
If you use xrandr to view/choose refresh rates, add this too:
Option "DynamicTwinView" "false"
There are more details in the driver's README. I think the nv driver has an option corresponding to the scaling one, but probably not the TwinView one.
