Microsoft originally added support for Windows 10 Mobile's Continuum for smartphone's that had Qualcomm's higher-end Snapdragon 808 or Snapdragon 810 processors inside. Now the company has officially added a third Qualcomm processor to the Continuum family: the Snapdragon 617.
The change was quietly made on Microsoft's Continuum support pages, but it had already been outed by Japan-based NuAns, who used the Snapdragon 617 inside the recently-launched NuAns Neo smartphone. That phone supports Continuum, which allows it to connect to a big screen monitor and be used like a PC with a connected keyboard and mouse.
The support page also mentions that a Continuum-based phone must have a display with at least a 720p resolution, 2GB of RAM and 16GB of internal storage. In other words a mid-range Windows 10 Mobile phone might be able to support Continuum but not a lower end device.
