Can't change refresh rate

[kremix]

hello all.
I am trying to set the refresh rate to something higher than the default 60Hz.

xrandr -q
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384
eDP connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 309mm x 174mm
1920x1080     60.00*+  48.00
1680x1050     60.00
1280x1024     60.00
1440x900      60.00
1280x800      60.00
1280x720      60.00
1024x768      60.00
800x600       60.00
640x480       60.00
HDMI-A-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-1 disconnected (normal left inverted right x axis y axis)

Attempt to change eDP to something higher than 60Hz:

xrandr --output eDP --mode 1920x1080 --rate 65

does nothing. no error only blank line in the terminal. changing to 48Hz and back to the 60 works. WTF?
how can I force refresh rate that isn't supported, any ideas? (sudo isn't helping either)

Voodo?
That maybe break your hardware.

If you really want to try and force your laptop's display to run at a higher rate than it says it is capable of, and are happy with breaking your laptop's display, then you can force a display mode:

Noone is going to help if you break your laptop's display though.
