Refreshing rate

[tajin]

I Installed: kmod-nvidia-96xx.i686 0:1.0.9631-4.2.6.19_1.2895.fc6 and xorg-x11-drv-nvidia-96xx.i386 0:1.0.9631-5.lvn6 for my nvidia Geforce 4 Mx440 video card.
But now the refreshing rate shown at KDE for my 17" Hansol 720Ed monitor after I installed nvidia on FC6, is 50 Hz (50~56 Hz.), and for nvidia settings

[tajin@localhost ~]$ nvidia-settings -q RefreshRate

Attribute 'RefreshRate' (localhost.localdomain:0.0; display device: CRT-0):
75.00 Hz.
'RefreshRate' is an integer attribute.
'RefreshRate' is a read-only attribute.
'RefreshRate' is display device specific.
'RefreshRate' can use the following target types: X Screen, GPU.

How do I correct this problem?, What's the refreshing rate I am having, what it comes out from nviidiasettings(75.0 Hz) or what it comes from KDE (50.0 Hz)?

Why is the refresh rate not reported correctly by utilities that use the XRandR X extension (e.g., the GNOME "Screen Resolution Preferences" panel, `xrandr -q`, etc)?

The XRandR X extension is not presently aware of multiple display devices on a single X screen; it only sees the MetaMode bounding box, which may contain one or more actual modes. This means that if multiple MetaModes have the same bounding box, XRandR will not be able to distinguish between them.

In order to support DynamicTwinView, the NVIDIA X driver must make each MetaMode appear to be unique to XRandR. Presently, the NVIDIA X driver accomplishes this by using the refresh rate as a unique identifier.

You can use `nvidia-settings -q RefreshRate` to query the actual refresh rate on each display device.

This behavior can be disabled by setting the X configuration option "DynamicTwinView" to FALSE.

From http://us.download.nvidia.com/XFree8...hapter-04.html

Note: If you disable DynamicTwinView you won't be able to change settings "on the fly" with nvidia-settings.

Hope this help.

Thanks Miltiad, my output with xrandr -q as you said is:

I don't know how to query with nvidia-settings -q RefreshRate both, my display and the monitor.
