All:
As of March 2, 2016 I continue to experience the problem described here. Specifically after returning from sleep I can see the camera activate and Windows Hello logs me in. However, the screen does not display.
Here is what I've found:
- I frequently use an external plugged directly into the SP4 using the Extend option. When coming out of sleep mode I found that if I press the
Windows-P, then home button, then Enter my SP4 internal display will come on.
For some reason the problem appears to be Windows not activating the internal display but, theoretically, having trouble with where to present the image. Resetting presentation mode back to internal monitor seems to resolve the issue. My system appears to
be stuck in extended mode because I can press the up arrow twice to get the same results. The problem even occurs if I manually perform these steps before disconnecting the external monitor.
I would be curios to know if others have a similar experience in that they are using an external monitor at some point in the process.
I suspect this can be resolved with an update from Microsoft once they get a handle on the cause of the problem.
I was having this problem with my desktop. It is a put together system with a ASUS board and i7 5th gen. I had the second monitor as my TV and it was left of the main monitor. The operating system kept identifying the main monitor as monitor 2. I could
not force the main monitor to be monitor 1 and when the computer woke it would look for the monitor 1 and place all the desk top items on that monitor. Even when that monitor was not on. (it might have appeared to the system to be on since the HDMI was switched
through a sound bar. This happened after I got a new monitor for the main monitor and switched from DVI to VGA for that main monitor.
I kept forcing the correct monitor by using the Win-P as you have been doing. Then one day it quit screwing up. Very strange. I sent a note to MS asking why I could not force the order of the monitors and have it stay. not sure if they heard. As far
as I know the system still makes the choice on which monitor identifies as number 1. Seems like we should be able to fix that if it is going to have an effect on operation.
On the subject of the wake from sleep. I had that and it is gone now as well. after the March 1 update all is well. not sure when it fixed because I went from Feb 19 to march 2 with the sleep disabled due to that problem.
