This host requires additional considerations, as it is using a 1440p display.

The following parts are modified:

• Polybar (.config/polybar/i3config.ini)
• Xresources (.Xresources)
• X11 (/etc/X11/xorg.conf.d/ new files)

Calculate Monitor size for desired DPI

To get the exact monitor size xorg wants for a target dpi, execute this command.

xrandr --dpi [DPI]

Querying the set dpi now yields the exact monitor size you'd want to set.

$> xdpyinfo | grep -B 2 resolution
screen #0:
  dimensions:    2560x1440 pixels (541x304 millimeters)
  resolution:    120x120 dots per inch
