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. - Image of gnome settings > displays > refresh rate

$ cat ~/.config/monitors.xml
<monitors version="2">
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 ?
