I just switch to an SP3 for work. 

I have it set up via a docking station with two external monitors, I am extending the desk top from the built in screen to the two externals.

Great set up for working, but I am having an issue.

It keeps dropping one of the two external displays (display 3) on start up.

Display 3 switches to standby but windows seems to think it is still operating.  I say this because windows seems to open items on display 3, and I can still move the mouse pointer through it and into another screen.

It's easily fixed by disconnecting monitor 3 and then extending desktop to it again, but doing this on start up is a PITA.

Pressing the power button on display 3 doesn't help.

Suggestions for a fix?



My video set up is as follows: -

-mDP to 2 x DP adapter plugged into the dock.
- 2 x DP to VGA adapters
- VGA cables to monitors (not DP compatible)
