Hello, I have an issues with setting refresh rates.
We have a RHEL5.3 box with a Quadro 4600 running nVidia Driver 195.36.24
One output is connected to an NEC flat panel at 1920x1200 50Hz which is fine.
The other output connects to a DLP projector which we want to run at 1920x1080 @24Hz.
In xorg I specifty a twinview setup and assign the displays as follows:
Option "MetaModes" "DFP-0: 1920x1080_24, DFP-1: 1920x1200"
I.e. I am specifically assigning the @24Hz mode to the projector.
When I start X, both screens come up at the requested resolution, but the projector comes up at 50Hz.
If I then run nvidia-settings, suddenly the correct refesh rate is applied and the projector detects 24Hz. I don't have to touch any settings, just starting nvidia-settings is enough.
Anyone any ideas what might be causing this?
I have poked through the X log (verbose mode) and it validates the modes I am trying to set and thinks they are set. xorg file attached.
