[Question] Display Management on tiling wm - eviltoast

BSPWM, laptop has 1920x1080 resolution, external screen has 1680x1050. xrandr --output DP-1 1680x1050 cuts image, if I change resolution to 1920x1080, I get “full” image, but quality is just bad. I have another machine with XFCE, it’s display utility does the trick and I wonder can I achieve smth similar on BSPWM with some simple console command?
