As an FYI, after updating to the Creator's Update Windows 10 version the graphics subsystems on the Surface Pro 4 seems to start behaving badly. This is especially true if connected to external monitors via a Surface Dock (Gen1 or Gen2).
An updated driver can be obtained here: Intel Iris 540 Driver for Windows 10
The SP4 had 15.44 while the download is 15.45 as of this writing!
