Question nVidia 24Hz refresh rate


I connected my TV to my computer using a HDMI cable and a DVI-HDMI adapter. When I tested in Windows XP I got it working when I changed refresh rate to 24 Hz, but in linux I haven't got it working at all so far.

I have tried to set the refresh rate to 24 Hz in linux as well, but I guess I didn't succeed...

In linux I installed the nVidia proprietary driver and ran the nvidia-settings command. These are my settings:
Code:
X Server Display Configuration
    Xinerama: disabled

    Model:         Samsung SyncMaster (CRT-0 on GPU-0)
    Configuration: Separate X screen
    Resolution:    Auto
    Refresh Rate:  Auto

    Model:         Sony TV (DFP-1 on GPU-0)
    Configuration: Separate X screen
    Resolution:    1980x1080
    Refresh Rate:  24 Hz

GPU 0 
  DFP-1
    Force Full GPU Scaling: Disabled
    GPU Scaling Method:     Stretched
    Color Space:            RGB
    Color Range:            Full
    Dithering:              Auto
      Mode:                 Auto
      Depth:                Auto
    Digital Vibrance:       0.000
    Overscan Compensation:  0
My /etc/X11/xorg.conf didn't exist, but I used the template /etc/X11/xorg.conf.install to create one.

This is my /etc/X11/xorg.conf:
Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 290.10  (buildmeister@swio-display-x86-rhel47-07.nvidia.com)  Wed Nov 16 20:31:58 PST 2011

Thumbs up

It turned out that I was quite close actually. Today I tested to enable Xinerama, and let nvidia-settings merge that setting into xorg.conf. Then I also had to redisable 'Force Full GPU Scaling' as it had been enabled for some reason.

And after restarting, it works!

Neat, solved your own question.
When done, mark your question "SOLVED" using the little button, so the rest of us know it is done.

What? That's exactly what I did wasn't it?
I marked this thread as solved using the link "Mark this thread as solved" directly when I posted my solution a week ago...
