Out of clues at the moment then... The Creator Update fixed this issue for some of us.
This indeed could be quite annoying.

My monitor (LG 29UM68) is connected to Surface Dock -> SP4, via direct miniDisplayPort.
It keeps entering sleep mode and waking up repeatedly, even though my SP4 is asleep. This does not happen when I connect the monitor to SP4 directly.
Another issue is that if I set to PC Screen Only, after few seconds, it will automatically switch back to external monitor only. Again, this does not happen if I connect monitor to SP4 directly.
These 2 issues only arise if I use Surface Dock.
I have gone through all the steps here (https://www.microsoft.com/surface/en-sg/support/hardware-and-drivers/troubleshoot-docking-station-surface-dock) successfully, but issue persist.
Please help.

2017-05-13T04:01:02+00:00 I am facing the same issue - monitor does not sleep properly. Quite sure the problem is with the dock, as it works fine when the external monitor is connected to the surface pro directly. Also see the issue only when connecting my monitor through display port wire, no issues with HDMI. (I still want to use display port connection as I can't get 60Hz with hdmi)
Did all software updates - did not help.
