xrandr --output HDMI-A-0 --scale 0.7x1
if you wanna use it replace HDMI-A-O with output of xrandr --prop | grep " connected" | awk '{print $1}
(and ofc 0.7x1 with whatever u want the scale to be)
still not a great solution... still playing windowed with small gaps, both vertically and horizontally because of 1280x1024 instead of 1350x1080
nvm im stupid just do xrandr --output HDMI-A-0 --scale <A>x<B>
where A = new_horizontal_resolution(e.g. 1280)/current_res(e.g. 1920) same for B but vertical; read man pages lmao (edited)
