I use three monitors with Windows 10 Pro on a PC with a Nvidia 1070.
I run Display Fusion Pro to help manage the monitors. I recently
purchased three large = a 32 inch and two 28 inch DELL 4K monitors. I
hooked them up using mini DisplayPorts. The 32 in the center and the
identical 28s on the right and left side. After I did that everything
went to hell. Windows seem to move where they want, When power save
comes on all the windows would move to monitor 1 and I would have to
manually put them back upon wake. When I shut them down and turned
them on in the morning everything was a mess. Desktop icons, window
postilions, task bars, everything. It has gotton to the point where
at the end of the day I close all the windows, and save icon
positions which is not how I want it to behave.
I was able to mitigate some of this with the help of Display Fusion
support by window position saving but it only kind of works. The
whole experience sucks given that I these three monitors were not
cheap. Apparently it is a known Win10 issue...from Display Fusion support>>>
The scrambling is likely happening because the 4K monitor is using a
DisplayPort connection. For some reason, when DisplayPort monitors
sleep, or power off, they get disconnected from Windows, so Windows
then forces all of the windows over to other monitors. Disabling
monitor sleep will prevent it from happening, but that's not ideal in
all cases for sure.
I have been screwing with this problem for a while and I can't
determine if Windows 10 or Nvidia drivers or both are at fault.
Anybody else seeing this?
