Those are the rates displayed by xrandr when nvidia dynamic-view is active.
nVidia had to use this design to properly handle dual-screen
configuration where each screen have its own refresh rate. So they
assign a unique rate figure for each configuration starting from 50.
nvidia-settings will show the proper refresh-rate.
Myth can also use nVidia NVCTRL X extension to retrieve the actual
refresh rate, so it's nothing to worry about.
If you want to get the proper refresh rate to show with xrandr,
disable dynamic twinview. xrandr can only handle refresh rate as
integer, so you will loose then the ability to differentiate 24Hx and
23.976Hz, or 60 vs 59.97
