Gnome overriding resolutions

Hello,

I've been struggling setting the resolution of the display of my Lenovo Yoga 2 Pro to anything else but 3200x1800. Some applications I use don't have HiDpi support (namely MatLab) so I figured it would be neat if I could set the display to 1920x1080 (or 1600x900 for that matter). After reading the respective pages on the ArchWiki on xrandr I added a new mode, assigned it to the correct display, but whenever I try to set it to 1080p it is automatically reverted to the previous resolution.

I think the problem lies with gnome. If I kill my gnome session and start an empty X server (with plain startx). I can set the resolution via xrandr just fine. I am not sure what the underlying framework is that influences this part and haven't had much result searching for this as I am clueless where this problem is originating from.

Can anyone point me in the right direction?

Regards.

P.S.
The procedure I've been using:

➜  ~  cvt 1920 1080 60
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
➜  ~  xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
➜  ~  xrandr --addmode eDP1 "1920x1080_60.00"
➜  ~  xrandr --output eDP1 --mode "1920x1080_60.00"

I've also tried setting it via Settings->Display to no avail.
