    When 4k displays on display port go standby or power down, the 1024x786 simulated displays mess up all window locations of my programs and desktop icons.



    The Problem

    Hi, in short the title should be sufficient to explain what's going on. However there's more going on.


    Apparently Windows 10, or the drivers, creates multiple profiles for each display scenario. This messes up the registry quite a bit and it causes a lot overhead, since I have no clue which profiles are actually being used. After some studying, I'm beginning to understand why it works this way and in a way it actually makes a lot of sense. Programs can keep running as if they still have a display and there is less traffic over the physical cables.


    However...

    It's totally mismatched. my current profile should exist of two 4k displays (3840x2160) and those should be equally simulated, to prevent distortions of the windows, it keeps squashing all my windows into the top corner of the primary display. And it's a very time consuming task to put them back where I want them.


    Cry for help!

    please tell me there is a fix for this or even an 3rd party app that can resolve this.

    Below is a screenshot of my (very messy) registry and the display configuration profiles.

    LMP Launches 4K 10-port USB-C Display Dock

    When it comes to video ports, the Display Dock has them all: HDMI (4K@60 Hz), Mini-DP (4K@30 Hz), DP (4K@30 Hz), DVI (1080p@60 Hz) and VGA (1080p@60 Hz). The Display Dock let's you extend your video content to two external displays (dual 4K monitor support via HDMI & Mini-DP/DP as well as further combinations with VGA and DVI), each at its maximum resolution and refresh rate. It is the only USB-C dock that supports 4K@60 Hz video output via HDMI and it comes at less than half the price of a Thunderbolt dock. Ideal for the professional user, the passionate movie fan or the avid gamer alike - take advantage of 4K video with high-frequency 60 Hz refresh rate.
