Configuring For HiDPI Displays Using GNOME¶

1. Open GNOME "Settings".
2. Navigate to "Displays".
3. Under "Scale" select the desired scale-factor, (e.g. 200%). The scale-factor should be up to the minimum size which is too big.
4. Get the output display name(s).

   $ xrandr --listmonitors
   

   Monitors: 2
    0: +*DP-0 3840/621x2160/341+3840+0  DP-0
    1: +HDMI-0 3840/621x2160/341+0+0  HDMI-0
   

   In the above example output, the two display names are "DP-0" and "HDMI-0" without double quotes.
5. Set the zoom-out factor.

   $ xrandr --output DP-0 --scale 1.75x1.75
   $ xrandr --output HDMI-0 --scale 1.75x1.75
   

6. Set the zoom-in factor.

   $ gsettings set org.gnome.settings-daemon.plugins.xsettings overrides "{'Xft/DPI': <153600>}"
