Windows 8.1: Screen errors

[PriCoSoft]

Usually everything works fine on my Lenovo Helix (Tablet).

But:
If the displays turn off (see Windows Power Management) after some minutes if could be (not always) that the connected displays on my Lenovo USB Dock are not recognized correctly.

This means my screen resolutions are wrong, the order of the Displays is incorrect and sometime one of them keeps in Stand-by/black.
After turning off the dock, wait until the main Screen flickers two times and then turn it back on often all works again. If I turn it on before the Screen flickers I need to restart my Computer to get it work again.

This problem persists since I'm using Windows 8.1. With Windows 8 it was working correctly.
