Can't change resolution on hidpi display - configure crtc 0 failed

Hi! First post here so if anything's wrong let me know, I'll try to be as specific as I can!
I recently bought a laptop, it is an Asus Zenbook (Model UX3402) with an OLED display. I have two monitors besides the laptop and I would like to configure the display to almost match the resolution in those (1920x1080). I say almost because the aspect ratio in this one is 16:10 so I could use 1920x1200. The display's native resolution is 2880x1800. The reason behind this is that the scaling is global under X.org and wayland is not an option (I mean, it is, but that brings a whole new set of issues like migrating from i3 to sway, screenshots and whatnot), so after trying every possible combination of drivers, WMs and window servers I went back to the original idea of lowering the resolution. It is an Intel i5-1240P.

But when I try to change it with xrandr I get the following error:

$ xrandr --output eDP-1 --mode 1920x1200 --verbose
crtc 0: disable
screen 0: 6720x1200 1777x317 mm  96.05dpi
crtc 0:    1920x1200  59.88 +0+0 "eDP-1"
xrandr: Configure crtc 0 failed
crtc 0: disable
crtc 1: disable
crtc 2: disable
crtc 3: disable
screen 0: revert
crtc 0: revert
crtc 1: revert
crtc 2: revert
crtc 3: revert

And the following in the X.org log

[  1871.579] (II) modeset(0): Allocate new frame buffer 6720x1200 stride
[  1871.717] (EE) modeset(0): failed to set mode: No such file or directory
[  1871.829] (II) modeset(0): Allocate new frame buffer 6720x1800 stride

If I try installing the package xf86-video-intel I can actually change the resolution, but that brings a lot of other issues like heavy flickering.

I end up on this topic https://bbs.archlinux.org/viewtopic.php?id=274530, which seems to be the closest thing to what I'm experiencing right now; so I was wondering, I could create an edid file with the desired resolution based on the original one and boot with that instead. The thing is that I'm not sure how to do that (already installed wxedid and played around a little bit with it, but I'm not sure about some of the values I should set).
