Was just coding some stuff, haven't tested yet.
I wouldn't be surprised if you couldn't compute the proper refresh
rate, because looking at the xrandr source code ; that's how they find
50, 51 etc.. By computing from the dotclock htotal and vtotal...

I did try with this.
xrandr then detects three available refresh rates for my TV: 50, 60
and 24. However, the screen will always be in 60Hz no matter what I
choose: 50 or 24.
nvidia-settings also reports that the refresh rate is 60Hz no matter
which rate I choose...

It won't work unfortunately.
And I also want to have 23.976Hz and 59.94Hz available ; which don't
show up if dynamic twinview is disabled.
