Dell XPS 15" InfinityEdge laptop is not 3 ft wide (1 metre)

[Dimitri John Ledkov]

$ xdpyinfo | grep -B2 resolution
screen #0:
  dimensions: 3840x2160 pixels (1016x571 millimeters)
  resolution: 96x96 dots per inch

The pixels are right, the dimensions in millimeters are off the charts.

It's just a laptop.....
