Without DPI forcing it returns nothing, with DPI forcing it returns the forced DPI (96/120)

> xrandr | egrep 'onnect|creen|\*' | grep -v disconn | sort -r
On laptop:

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 16384 x 16384
DP-4 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
   1920x1080     60.02*+  48.00

On desktop more or less the same but the screen dimensions are 527mm x 296mm

> xdpyinfo | egrep 'dimen|ution'
On laptop:

  dimensions:    1920x1080 pixels (341x190 millimeters)
  resolution:    143x144 dots per inch

On desktop:

  dimensions:    1920x1080 pixels (530x301 millimeters)

Note that the on desktop I have 120 DPI set in TCC, whereas on laptop I don't force any DPI at the 
moment.

The page reports the same DPI as xdpyinfo (143 on laptop, 92 on desktop), regardless of what is 
set in TCC.
