xrandr options are different from settings > displays on gnome / ubuntu 20.04


$ xrandr
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
HDMI-0 disconnected (normal left inverted right x axis y axis)
eDP-1-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
  1920x1080    60.05 +  60.01*  59.97    59.96    59.93 
  1680x1050    59.95    59.88 
  1600x1024    60.17 
  1400x1050    59.98 
  1600x900      59.99    59.94    59.95    59.82 
  1280x1024    60.02 
... others options

xrandr man page says: if invoked without any option, it will dump the state of the outputs, showing the existing modes for each of them, with a ‘+’ after the preferred modes and a ‘*’ after the current mode.
Based on that xrandr output I’m assuming my monitor is using 60Hz, but my gnome settings > displays is showing me I’m using 120Hz.

$ cat ~/.config/monitors.xml

          0x61ed           0x00000000

My question is: Which is right? My monitor doesn’t support 120Hz and is using 60Hz based on xrandr or it’s really using 120Hz based on gnome settings and ~/.config/monitors.xml ?
