[SOLVED] nVidia 24Hz refresh rate

ekj · 12-17-2011, 04:21 PM

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:

Anyone having any idea about any solution?

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.

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...
