EDID override with CRU seems not to be working ?

[MisterT]

Hey folks

I am using Windows 10 with two displays connected both with displayport 1.2.
I was frustrated about that If I am turning off my monitor that all my windows moving around (mostly to primary display).
I have read EDID override is a workaround for that and found CRU tool here but it seems that CRU wont work for me ?

I have done the following:
1. Downloaded CRU.
2. Followed these instructions (I did it for both displays same way):

3. I added these (I have a g-sync monitor): Clicked on "Edit..." next to the displays drop down menu at the top and setup the right refresh rates for both display and had activate "include if slot available under range limits.
4. Clicked ok to close CRU and executed restart64.exe (no errors and all is working fine till now).
5. Restarted windows 10 - just to be sure

But then I had tested it: disabled second monitor and again... All opened windows on second monitor was moved to primary display after I re-enabled my second monitor :'(

Some info:
Windows 10 Pro (1803 - all newest updates installed) x64
NVIDIA GTX 1070 (single card)
Nvidia driver version: 417.35 (newest)
CRU version: 1.4.1

Is there something wrong or misunderstood ? Hope someone can help me out, its really frustrating :/

greetings

EDIT: With this steps above I dont see any youtube videos - I hear audio but video itself is only black (I have gpu acceleration enabled).
What I have to do in CRU to watch youtube properly again with gpu acceleration enabled ?
