I have tried today’s version of the next Ubuntu (16.04) -> the problem hasn't been resolved. The system behaves as my current instillation (15.10) before log-in: ".. two Dell screens, laptop's screens got off. The Dell screens are properly detected as separate: I can move mouse from one screen to another. Image on the last Dell screen is defected (blur) as in the attached picture."
