--- Comment #2 from Alex Deucher <alexdeucher at gmail.com> ---
This is handled at the Desktop level.  There are quite a few large format
displays that show up as multiple DP MST displays, even a number of early 4k
displays.  X exposes the tile info via randr 1.5 and the desktop environment
should handle it as a single monitor.  Mutter handles this in GNOME for
example.
