[SOLVED] missing resolution on XPS 13 9370

Hello,

I'm unable to get the full resolution of my XPS 13 under arch.
The resolution should allow up to 3840x2160 but xrandr only sees 1920x1080.
Any help would be much appreciated

$ xrandr -q

I tried to add a new resolution with no success

Re: [SOLVED] missing resolution on XPS 13 9370

well I actually solved my issue by removing `xf86-video-intel`

sudo pacman -R xf86-video-intel
