WHAT THIS IS
------------
The DELL LATITUDE E7440's docking station supports two external displays, and
the notebook's Haswell architecture supports having three displays active at

$ xrandr
Screen 0: minimum 320 x 200, current 5280 x 1080, maximum 32767 x 32767
eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 309mm x 174mm
