Looks like scaling ought to be able to fixed using the monitor's setup menu:
Nope, already looked into that. User 2560x1440 and the the monitor scaling just stretch everything horizontally.
The fact that the engine can already do the above resolution means that 3440x1440 is just a code fix, so am going to raise a tracker.
